Rearrange terms
-16=(- 4)- 6 x
-16=-6x - 4
Add 4 to both sides
-16= - 6x - 4
-16 + 4= -6x - 4 + 4
Simplify the expression
-16+4=6x - 4+4
-12=6x

Elmer invested $100 into a savings account that earns annual simple interest. At the end of 3 years, he earned $15 in interest. What is the interest rate on the savings account? Round to the nearest tenth of a percent.
Answer:
To find the interest rate, we can use the formula for simple interest:
I = Prt
Where:
I = Interest earned
P = Principal (initial investment)
r = Interest rate
t = Time
We are given that P = $100, t = 3 years, and I = $15. Substituting these values, we get:
15 = 100 * r * 3
Solving for r, we get:
r = 15 / (100 * 3) = 0.05
Therefore, the interest rate on the savings account is 5%.
How many solutions and what is the solution? please help
One solution: (6,2)
Step-by-step explanation:Systems of equations are a set of equations that share variables.
Number of Solutions
There are multiple ways to find the number of solutions to a system of equations. Firstly, if 2 lines are parallel, then there will never be a point that satisfies both equations. This means that there will be no solutions. If 2 equations create the same line, then there will be infinitely solutions. Lastly, if there are 2 linear lines that are not parallel or the same, then they will have exactly one solution.
Solving Systems of Equation
The solution to a system of equations is the point that makes both equations true. When looking at a graph, the solution to a system of equations will be where the lines intersect. In this question, the lines intersect at (6,2). This means the solution to the system of equations is (6,2).
Make an expression with 4 terms where 3 of them are like terms.
2. Rewrite the expression by combining like terms. How many terms are there?
please help
Answer:
Step-by-step explanation:
An example of an expression with 4 terms where 3 of them are like terms is:
$5x^2 + 7x - 2x^2 + 3x$
To rewrite this expression by combining like terms, we add the coefficients of the terms with the same variables raised to the same power. In this case, the two terms with $x^2$ are like terms, so we can add their coefficients:
$5x^2 - 2x^2 + 7x + 3x = 3x^2 + 10x$
The resulting expression has 2 terms.

Can the sides of a right triangle have lengths 5, 15, and √250? Explain.
A triangle must have a third side that is bigger than the sum of any two of its sides. There cannot be a triangle with these side lengths because in this instance, 5 + 15 = 20 is not greater than 250.
Application of Pythagoras theoremTo check whether the given lengths can form the sides of a right triangle, we need to check if they satisfy the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Let's label the sides of the triangle as a, b, and c, where c is the hypotenuse. Then, the Pythagorean theorem can be written as:
a^2 + b^2 = c^2
Plugging in the given values, we get:
5^2 + 15^2 = (√250)^2
Simplifying the left-hand side, we get:
25 + 225 = 250
This is not true, since 25 + 225 = 250 does not hold. Therefore, the given lengths cannot form the sides of a right triangle.
In fact, we can see that the given lengths violate the triangle inequality, which states that the sum of any two sides of a triangle must be greater than the third side. In this case, 5 + 15 = 20 is not greater than √250, so a triangle with these side lengths cannot exist.

In circle C with the measure of minor arc BD=42°, find mBED.
Answer: mBED = 2(42°) = 84°
Step-by-step explanation:
We are asked to find the measure of the central angle ∠BED in the circle given that the measure of the minor arc BD is 42°.
We can use the formula that states that the measure of a central angle is equal to twice the measure of its intercepted arc. That is,
m∠BED = 2*mBD
We can substitute the value of mBD, which is 42°, into our equation.
m∠BED = 2*42°
m∠BED = 84°
Therefore, the measure of the central angle ∠BED is 84°.

The Gordon family plans to buy a TV. One TV has a purchase price of $330 and an estimated yearly operating cost of $14. The other has a purchase price of $369 and an estimated yearly operating cost of $9. Which TV should the Gordons buy if they plan to keep it for 8 years? Use rational functions to help justify your answer.
ANSWER:rational functions that model the average annual cost of each television if it is owned for x years, such as f(x)= (330+14x)/x and
g(x)= (369+9x)/x
calculation proving that over 8 years, the annual cost for the $330 television is $55.25; for the $369 television, it is $55.13
statement that the Gordons should buy the $369 television because it is less expensive overall
step by step: edge 2023
Answer:
The Gordon's should buy TV2
Step-by-step explanation:
To determine which TV the Gordons should buy, we need to compare the total cost of each TV over the 8-year period. Let's define some variables:
- Let x be the number of years the TV is used.
- Let y1 be the total cost of TV 1 over x years.
- Let y2 be the total cost of TV 2 over x years.
- Let P1 be the purchase price of TV 1.
- Let P2 be the purchase price of TV 2.
- Let O1 be the annual operating cost of TV 1.
- Let O2 be the annual operating cost of TV 2.
Using these variables, we can write the following equations:
y1 = P1 + x * O1
y2 = P2 + x * O2
To compare the total cost of each TV over 8 years, we need to find y1 and y2 when x = 8. Plugging in the given values, we get:
y1 = 330 + 8 * 14 = 462
y2 = 369 + 8 * 9 = 441
Therefore, the total cost of TV 1 over 8 years is $462, and the total cost of TV 2 over 8 years is $441. Since TV 2 has the lower total cost, the Gordons should buy TV 2.
From a mathematical standpoint, we can also use rational functions to analyze this problem. The total cost of each TV is a linear function of x, so we can write:
y1(x) = P1 + x * O1
y2(x) = P2 + x * O2
The ratio of these functions is:
y1(x) / y2(x) = (P1 + x * O1) / (P2 + x * O2)
To determine which TV is cheaper over 8 years, we need to compare the ratios when x = 8:
y1(8) / y2(8) = (330 + 8 * 14) / (369 + 8 * 9) ≈ 1.051
Since this ratio is greater than 1, TV 1 is more expensive than TV 2 over 8 years. Therefore, the Gordons should buy TV 2.

If f(x)=3x-5, g(x)=7x-3, find (f+g)(x) and (f-g)(x
Answer:
Step-by-step explanation: To find (f+g)(x), we simply add the two functions:
(f+g)(x) = f(x) + g(x)
= (3x - 5) + (7x - 3)
= 10x - 8
Therefore, (f+g)(x) = 10x - 8.
To find (f-g)(x), we subtract g(x) from f(x):
(f-g)(x) = f(x) - g(x)
= (3x - 5) - (7x - 3)
= -4x - 8
Therefore, (f-g)(x) = -4x - 8.

make and hang the drapes is $250. She uses the expression
15x + 250 to calculate the total cost of the drapes. Mrs.
Andretti states that x represents the total cost of the fabric.
Is she correct?
• Yes, x represents the total cost of the fabric.
O No, x represents the total cost of the drapes.
• No, x represents the total yards of fabric used.
O No, x represents the total amount of fabric she
already has.
Fabric cost ($15 per yard) and curtain making and hanging ($250). x represents the total cost of the fabric and Mrs. Andretti can use the formula 15x to calculate the fabric cost and add the $250 fixed charge to get the total cost of the curtain.
Why do we determine costs?Cost computation helps in deciding on pricing, manufacturing output, and sales. It also helps in figuring out the costs of the products and services the company sells.
X does not represent the cost of fabric. X represents the number of yards of fabric used.
15x + 250
Could be read as ($15 × # of yards) + $250
She must therefore pay $15 per yard of cloth in addition to the $250 base cost of having them produced and hung.

Tiger Global Management had R6 500 000 in sales last year. The company’s total comprehensive income was R217 000, its total assets turnover was 1,04, and the company’s return on equity (ROE) was 14%. The company is financed entirely with debt and common equity. What is the company’s debt ratio?
Answer:
Step-by-step explanation:
To calculate the company's debt ratio, we need to know its total liabilities and total assets. We can use the total assets turnover ratio to calculate the company's total assets:
Total assets turnover = Sales / Total Assets
1.04 = R6,500,000 / Total Assets
Total Assets = R6,500,000 / 1.04 = R6,250,000
Since the company is financed entirely with debt and common equity, its total liabilities are equal to its total debt. We can use the return on equity (ROE) formula to calculate the company's total equity:
ROE = Net Income / Total Equity
0.14 = R217,000 / Total Equity
Total Equity = R217,000 / 0.14 = R1,550,000
Now, we can calculate the company's debt ratio:
Debt Ratio = Total Debt / Total Assets
Debt Ratio = (Total Assets - Total Equity) / Total Assets
Debt Ratio = (R6,250,000 - R1,550,000) / R6,250,000
Debt Ratio = R4,700,000 / R6,250,000
Debt Ratio = 0.752 or 75.2%
Therefore, the company's debt ratio is 75.2%.

The average rate of change representing the state whose temperature is decreasing slower is given as follows:
-1.5ºF/day.
How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For Maine, in 9 days, the temperature fell by 13.5ºF, hence the rate is given as follows:
-13.5/9 = -1.5ºF/day.
For Connecticut, in 2.5 days, the temperature fell by 6.25ºF, hence the rate is given as follows:

Two skaters are practicing at the same time on the same rink. A coordinate grid is superimposed on the ice. One skater follows
the path y = - 3x + 8, while the other skater follows the curve y= - 2x^2 + 7x. Find all the points where they might collide if they
are not careful.
Answer: To find the points where the two skaters might collide, we need to find the values of x and y that satisfy both equations:
y = -3x + 8
y = -2x^2 + 7x
We can set the two equations equal to each other and solve for x:
-3x + 8 = -2x^2 + 7x
This simplifies to:
2x^2 - 10x + 8 = 0
Dividing both sides by 2, we get:
x^2 - 5x + 4 = 0
Factoring the left side, we get:
(x - 1)(x - 4) = 0
So the solutions for x are x = 1 and x = 4.
To find the corresponding values of y, we can substitute these values of x into either equation. Let's use y = -3x + 8:
When x = 1, y = -3(1) + 8 = 5
When x = 4, y = -3(4) + 8 = -4
Therefore, the two skaters might collide at the points (1, 5) and (4, -4).

The figure below represents 17/36 of a full circle. Find the measure of the marked central angle.
The specified central angle is 170 degrees since the figure is 17/36 of a full circle.
A central angle is an angle with endpoints on the perimeter and a vertex in the centre of a circle. An arc is defined by the angle in the centre of a circle.
Since the figure represents 17/36 of a full circle, the central angle that it subtends is also equal to 17/36 of 360 degrees (the measure of a full circle).
We can calculate this as follows:
Central angle = (17/36) x 360 degrees
