In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.
<h3>What is the variables about?</h3>
Note that:
y=-8x+4
y-4=-8x
(y-4)/-8=x
Since the independent variable x is known, one can switch the variable labels and thus it will be:
y=(x-4)/-8
f^-1(x)=(x-4)/-8
This can be written again as:
f^-1(x)=(4-x)/8 :P
Thus one can say No, as he forgot to switch the variable labels after solving for the independent variable.
In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.

Answer:
B. $25.50
Step-by-step explanation:
On this question you have to subtract 6 dollars from one of the answers and add that same amount back on because that would equal the total amount of lunch money. A wouldn't work because 31.50-6+31.50 is over 45 dollars. When you have 25.50-6+25.50 you get 45!
Given:
The parking space shown at the right has an area of 209 ft².
A custom truck has rectangular dimensions of 13.5 ft by 8.5 ft.
To find:
Whether the truck fit in the parking space or not?
Solution:
If the area of the truck is more than the area of the parking space, then the truck cannot fit in the parking space otherwise it will fit in the parking space.
The area of a rectangle is:

Area of the rectangular truck is:


The area of the truck is 114.75 ft² which is less than the area of the parking space, 209 ft².
Therefore, the truck can fit in the parking space because the area of the truck is less than the area of the parking space.
