1. Identify the slope and y-intercept of the following equation: y = 9x - 3
Answer:
Step-by-step explanation:
Hey :)
Keep in mind:
y = mx + b
Where m = slope and b = y-intercept
Since we are told:
y = 9x - 3
This means m = 9 and b = -3
Therefore the slope is 9 and y-intercept is at (0,-3)
A line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5. What is the value of n?
The slope of y = 2x - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points A and B is also 2. This means
(8 - 4) / (6 - n) = 2
Solve for n :
4 / (6 - n) = 2
4/2 = 6 - n
2 = 6 - n
n = 6 - 2
n = 4

Monty buys hats in bulk to sell at his store. His cost for each hate is $17. He marks up the hats 45%. What is the retail price per hat?
The required retail cost of the hat before the markup is 11.73.
Given that,
Monty buys hats in bulk to sell at his store. His cost for each hate is $17. He marks up the hats 45%. What is the retail price per hat is to be determined.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
here,
Let the retail cost be x,
According to the question, the retail price is markup by 45%.
So the cost after mark up = x + 0.45x = 1.45x
And
17 = 1.45x
x = 17 / 1.45
x = 11.73
Thus, the required retail cost of the hat before the markup is 11.73.

Solve the equation shown:
-5(x - 3) +7x = 35
x =
Answer:
10
Step-by-step explanation:
[tex]-5(x-3)+7x=35[/tex]
Distribute the 5
[tex]-5x+15+7x=35[/tex]
Combine like terms
[tex]2x+15=35[/tex]
Subtract 15 to isolate the variable
[tex]2x=20[/tex]
Divide by 2
[tex]x=10[/tex]
Answer:
x = 10
Step-by-step explanation:
Simplify by applying the distributed property: -5x - -15 + 7x = 35Simplify: -5x + 15 + 7x = 35Combine like terms: 2x + 15 = 35Subtract 15 from each side, so it now looks like this: 2x = 20Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 10I hope this helps!

Answer:
:) /
Step-by-step explanation:,,
Answer:
The answer is B:subtract 1,add x,divide by 4
The other answer is D:add x,subtract 1,divide 4
Step-by-step explanation:
when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3
the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=[tex]\frac{3}{4}[/tex]
The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=[tex]\frac{3}{4}[/tex]
With that evidence I can reasonably say that answer to the question is B,and D

Step-by-step explanation:
Your asking for the common factor between the answer 6 and 3 correct if you are here:
Answer:
GCF = 3
for the values 3, 6
Solution by Factorization:
The factors of 3 are: 1, 3
The factors of 6 are: 1, 2, 3, 6
Then the greatest common factor is 3.
2.072539 rounded to the nearest hundredth
Answer:
2.07
Step-by-step explanation:
Answer:
2.07
Step-by-step explanation:
The reason for that is if the thousandths place was greater that 5 it will change the 7 to an 8
so when rounding the number will change if it is greater than 5
if less than it will stay the same and the rest will become 000 after it
2.07000 but an easier way to say it is 2.07

open circle on -3 and all numbers to the right shaded
open circle on -3 and all numbers to the left shaded
Answer:
The second one
Step-by-step explanation:
The true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.
What is Number system?A number system is defined as a system of writing to express numbers.
A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.
The given inequality is x>-3.
The value of x should be greater than -3.
The value -3 is not included.
In a number line the values are increased from left to right.
As x is greater than -3 which means the x values are increasing from left to right.
So the statement open circle on -3 and all numbers to the right shaded is true statement.
Hence, the true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

Complete the steps to derive the cofunction identity.
Answer:
See below
Step-by-step explanation:
In order to derivate the cofunction identity, we will use the difference identity for sine.
[tex]\boxed{\sin(\alpha-\beta ) =\sin(\alpha )\cos(\beta ) - \cos(\alpha )\sin(\beta ) }[/tex]
[tex]\sin \left(\dfrac{\pi}{2} - x\right) =\sin \left(\dfrac{\pi}{2}\right)\cos(x) -\cos\left(\dfrac{\pi}{2}\right) \sin(x)[/tex]
Once
[tex]\sin \left(\dfrac{\pi}{2}\right) = 1[/tex]
[tex]\cos\left(\dfrac{\pi}{2}\right) = 0[/tex]
[tex]\sin \left(\dfrac{\pi}{2} - x\right) =1 \cdot \cos(x) -0\cdot \sin(x)[/tex]
[tex]\sin \left(\dfrac{\pi}{2} - x\right) = \cos(x)[/tex]
