Step-by-step explanation:
Hello!
We can solve the inequality for y by dividing both sides by 7.
Remember, when dividing or multiplying both sides of an inequality with a negative number, make sure to flip the sign. Since 7 is positive, we don't have to flip the sign.
Solve the Inequality63 > 7y63/7 = 7y/79 > ySo the inequality is true for all y values less than 9.

With the exception of column one, all amounts are in dollars. What is starting principal of the loan? Give your answer in dollars to the nearest dollar. Do not include commas or the dollar sign in your answer.
Answers
SOLUTION
First let us get the monthly rate
This can be gotten using the formula
[tex]P\times\frac{r}{12}=i[/tex]Where P is principal,
r is the percent interet rate per year, so to get monthly interest is divide by 12
i is the monthly interet.
Using column 1 to determine the rate, we have
[tex]\begin{gathered} P\times\frac{r}{12}=i \\ 149,783.55\times\frac{r}{12\times100}=748.92 \\ \frac{149,783.55r}{1200}=748.92 \\ r=\frac{1200\times748.92}{149,783.55} \\ r=6\text{ percent} \end{gathered}[/tex]Now, the interest rate r = 6%
The starting principal becomes
[tex]\begin{gathered} P\times\frac{6}{12\times100}=750 \\ \frac{6P}{1200}=750 \\ P=\frac{750\times1200}{6} \\ P=150000\text{ dollars } \end{gathered}[/tex]Therfore, the answer is 150000 dollars

Given f(x)=2x-5, describe how the graph of g compares with the graph of f.
g(x)=2(0.2x)-5
Answers
The graph of g and f have equal intercepts while the slope of the graph of f is 5 times larger than the slope of the graph of g
How to compare the graph of g with the graph of fGiven: f(x) = 2x-5 and g(x)=2(0.2x)-5
To compare the two graphs, we can make use of the equation of a line:
The general form of the equation of a line is y = mx + c
Where m is the slope and c is the intercept
So we will compare two the functions with the equation of a line:
Comparing f(x) = (2x-5) with y = mx + c
The slope(m) of the line = 2 and the intercept(c) = -5
Also, comparing g(x) = 2(0.2x)-5 with y = mx + c
The slope(m) of the line = 2(0.2) = 0.4 and the intercept(c) = -5
Since the slope of f(x) = 2 and the slope of g(x) = 0.4. Thus:
slope of f(x) / slope of g(x) = 2/0.4 = 5
So we can say the slope of f(x) is 5 times the slope of g(x)
Therefore, the graph of g and f have the same intercept. But the slope of f(x) is 5 times the slope of g(x)

A)Angle A and B are vertical angles, meaning they are equal in measure. We can solve for y by setting the two equations equal to each other.
Vertical angles are the opposite angles formed by the intersection of 2 lines.
Supplementary angles are angles that add up to 180°.
Solve for y4y - 25 = 674y = 92y = 23The value of y is 23°.

The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9
How to determine the quadratic equation?From the question, the given parameters are:
Roots = (-1 - √2)/3 and (-1 + √2)/3
The quadratic equation is then calculated as
f(x) = The products of (x - roots)
Substitute the known values in the above equation

Answers
The net amount due on the order after partial payment done is $8700
Given,
A retailer purchases some merchandise;
The invoice price for the merchandise = $19,500
Terms of sale for the merchandise = 5/15, n/45
On 15th day partial payment done = $10,800
We have to find the net amount due on the order after partial payment is done.
Here,
Net amount due = Invoice price - Partial payment

The dimension are 75 * 50 i.e, Width = 50 cm , Length = 75 cm
Define Dimension
A measurable extent of a particular kind, such as length, breadth, depth, or height.
Let,
T = how taller the poster is
W = how wide the poster is
According to question given,
T = W + 25 ---eq(i)
The total height is calculated by multiplying the top border by 5 and the bottom border by 5. The entire height is then multiplied by the border's width, 5, times 2, so there are two tall sides. then multiplying by 5 times 2 widths.The equation looks like that,
5 * (2 (T + 10)) + 5 * (2 * W) = 1350
Now substitute the eq(i) value,
5 * (2 ((W + 25) + 10)) + 5 * (2 * W) = 1350
Now, solve for W,
5 * (2W +50 + 20) + 10W = 1350
10W + 5(70)+ 10W = 1350
20W + 350 = 1350
20W = 1350 - 350
20W = 1000
W = 1000/20
W = 50
Now, put the W value in eq(i)

Answers
Quinn got paid $121,560 in his first career and on switching, he made 55% less, i.e. he made 45% of his previous career.
This is because, if in a previous career he made 100%, then a 55% reduction in salary annually would mean, he is left with only 45%.
Let us suppose, previous salary as x
then, x= $121,560
so, 45% of x= 45% of $121,560
i.e. 45% of x= 45/100 x 121560
therefore, 45% of x= $54,702
Quinn makes $54,702 now.
Therefore, a reduction in 55% of earlier salary would mean that Quinn's salary reduced from $121,560 to $54,702

The equation of the line that is perpendicular to y = x + 6 is expressed as: y = -x - 7
How to Write the Equation of a Line?The equation of a line can be written as y = mx + 1. The value of m is the slope while the value of b is the y-intercept.
The slopes of two lines that are perpendicular to each other are negative reciprocals. This means, if we multiply their slope values together, we will get -1.
Given the line, y = x + 6, the slope of the line is 1. The slope of the line it is perpendicular to is -1, because -1 is the negative reciprocal of 1.
Substitute m = -1 and (x, y) = (2, -9) onto y = mx + b to find the value of b:
-9 = -1(2) + b
-9 = -2 + b
-9 + 2 = b
-7 = b
b = -7
To write the equation of the perpendicular line, substitute m = -1 and b = -7 into y = mx + b:
y = -x - 7
