Option D:
Solution:
Given function:
To find the inverse of the function.
<u>Inverse of a function:</u>
<em>If a function f(x) is mapping x to y, then the inverse function of f(x) maps y back to x.</em>
Interchange the variables x and y.
Now, solve for y.
Multiply both sides by (y - 5).
Cancel the common factors, we get
Divide by x on both sides.
Add 5 on both sides.
To make the denominator same, multiply the 2nd term by 
.
Option D is the correct answer.
Answer:
A) x+5
B) 121
Step-by-step explanation:
A) If Tim is 5 pounds heavier than Amy, an equation for this situation can be modeled by x+5, where Amy is <em>x </em>pounds.
B) If Tim is 126 pounds, then Amy's weight is 126-5=121 pounds.
You can do 109 divide by 100 then multiply it by the percent you need 109/100= 1.09*57=62.13

Step-by-step explanation:
Answer:
The probability that a car chosen at random is not red is 75%.
Step-by-step explanation:
Given that a used car dealer sells SUVs and cars, and of all the vehicles, 60% are cars, and of all the vehicles, 15% are red cars, to determine what is the probability that a car chosen at random is not red you must perform the following calculation:
60 = 100
15 = X
15 x 100/60 = X
25 = X
100 - 25 = 75
Therefore, the probability that a car chosen at random is not red is 75%.
