You are going to attend night classes for 4 months. You have to earn an additional $987 for tuition within this time. You decide to take a second job that pays $9 dollars an hour. You can work as many hours for this job as you like. Taxes are 12% of your earnings, and you are able to save the rest. Over these 4 months, what is the minimum number of hours you will need to work in order to save enough money for your tuition alone? Round your answer to the nearest hour.
Answer:
10.80
Step-by-step explanation:
12% of $9 dollars is $1.08 rounded is 1.080
btw if this was a real job id quit even though im in 6th
The minimum number of hours you will need to work in order to save enough money for your tuition alone is 125 hours.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
You are going to attend night classes for 4 months. You have to earn an additional $987 for tuition within this time.
You decide to take a second job that pays $9 dollars an hour.
Taxes are 12% of your earnings, and you are able to save the rest.
Let x be the minimum number of hours you will need to work in order to save enough money for your tuition alone.
From the data given, we can frame a linear equation in one variable.
987 = 9x - 12% of 9x
987 = 9x - (0.12)(9)x
987 = 9x - 1.08x
7.92x = 987
x = 987/7.92
x = 124.62 ≈ 125 hours
Thus, the minimum number of hours you will need to work in order to save enough money for your tuition alone is 125 hours.

The y-intercept of any function is the value of the function when x = 0.
The y-intercept of f(x) is f(0) = 4(0) - 1. This is equal to -1.The y-intercept of g(x) is g(0), which we can see from the graph is 2.The y-intercept of h(x) is h(0), which is cos(0 + 2pi). This is equal to 1.Therefore, g(x) has the greatest y-intercept.

Using these coordinates, find the slope. (0, -6), (3, -2)
Answer:
The slope between the points (0, -6) and (3, -2) will be:
[tex]m=\frac{4}{3}[/tex]Step-by-step explanation:
Given the points
(0, -6)(3, -2)The slope between the points (0, -6) and (3, -2) will be:
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

Tia dilated the rectangle below by a scale factor of 7/2. What is ther perimeter of the new rectangle?
A
64 inches
B
220 inches
C
2695 inches
D
224 inches
Answer:
D. 224 inches
Step-by-step explanation:
Length of the new rectangle after dilation = 22 × ⁷/2 = 77 inches
Width of the new rectangle after dilation = 10 × ⁷/2 = 35 inches
Perimeter of rectangle = 2(length + width)
= 2(77 + 35)
= 2(112)
Perimeter = 224 inches
The difference between two whole numbers is 9. Twice the smaller number is 6 more than the larger. What is the smaller number?
The smaller number is 15
let
the larger number = x
the smaller number = y
Therefore,
The difference between the two whole numbers is 9 can be express as follows:
x - y = 9Twice the smaller number is 6 more than the larger. Therefore,
2y = x + 6Combine the equation.
x - y = 9
-x + 2y = 6
y = 15
x - 15 = 9
x = 9 + 15
x = 24
Therefore,
The larger number = 24
The smaller number = 15

Step-by-step explanation:
You can identify the lines by the sign of the slope and the value of the y-intercept. Each point of interest is at the intersection of a line with positive slope and a line with negative slope. So, you can identify the pair of lines by their two different y-intercepts.
Clockwise from lower left (3rd quadrant), the pairs of y-intercepts associated with the intersection of interest are ...
2, -1 . . . . 2 is associated with positive slope2, 22, -1 . . . . 2 is associated with negative slope2, -3-1, -3If the answer choices are designated A–E, left to right, the corresponding list is (again, clockwise from lower left) ...
DCBAELOTS OF POINTS!?!?!?Write a linear function f with the values f(5)=−1 and f(0)=−1.
f(x)=
Answer:
The euation of the linear function is:
y = -1Step-by-step explanation:
As the function has the values
at x = 5, f(5) = -1at x = 0, f(0) = -1Thus, the two points are:
(5, -1)(0, -1)Finding the slope between (5, -1) and (0, -1)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)[/tex]
[tex]m=\frac{-1-\left(-1\right)}{0-5}[/tex]
[tex]m=0[/tex]
We know that the slope-intercept form of the line equation is
y=mx+b
where m is the slope and b is the y-intercept
We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.
so at x = 0, y = -1
Thus, the y-intercept 'b' = -1
Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation
y = mx+b
y = 0x + -1
y = -1
Therefore, the euation of the linear function is:

f(x) = 2(x – 1)– 5 and g(x) = – 2x + 1 , determine the x-values of the points of intersection.
Answer:
x = 2Step-by-step explanation:
These are equations of lines with different slopes, so there is only one point of their intersect.
The point of intersect is where f(x) = g(x).
2(x - 1) - 5 = - 2x + 1
+2x +2x
2x - 2 - 5 + 2x = 1

4x = 8
÷4 ÷4
x = 2
Answer: x = 2
Explanation:
From the way you were referring to the x-values as plural, I assumed there were multiple x-values and multiple points of intersection, but these are linear equations, so one x-value it is!
Simply f(x)=2(x-1)-5 into f(x)=2x-7. Just plug in 2x-7, in order to make it equal to -2x+1. That would make the equation 2x-7=-2x+1. Add 7 to both sides to make it 2x=-2x+8. Add 2x to both sides to make it 4x=8. Divide 4 to both sides and that results with x=2.

7)Let's solve your equation step-by-step.
4x+34=8−9x
Step 1: Simplify both sides of the equation.
4x+34=8−9x
4x+34=8+−9x
4x+34=−9x+8
Step 2: Add 9x to both sides.
4x+34+9x=−9x+8+9x
13x+34=8
Step 3: Subtract 34 from both sides.
13x+34−34=8−34
13x=−26
Step 4: Divide both sides by 13.

11) Let's solve your equation step-by-step.
2x−18=−9−x
Step 1: Simplify both sides of the equation.
2x−18=−9−x
2x+−18=−9+−x
2x−18=−x−9
Step 2: Add x to both sides.
2x−18+x=−x−9+x
3x−18=−9
Step 3: Add 18 to both sides.
3x−18+18=−9+18
3x=9
Step 4: Divide both sides by 3.
Answer:
x=3
8) Let's solve your equation step-by-step.
−x−7=3x−7
Step 1: Subtract 3x from both sides.
−x−7−3x=3x−7−3x
−4x−7=−7
Step 2: Add 7 to both sides.
−4x−7+7=−7+7
−4x=0
Step 3: Divide both sides by -4.
−4x /-4=0 /-4
x=0
12)
x=3/4=0.750
We move all terms to the left:
x-(3/4)=0
We add all the numbers together, and all the variables
x-(+3/4)=0
We get rid of parentheses
x-3/4=0
We multiply all the terms by the denominator
x*4-3=0
Wy multiply elements
4x-3=0
We move all terms containing x to the left, all other terms to the right
4x=3
x=3/4
