Let's say that h(x) = x+3. To find the inverse switch h(x) and x and call h(x) by its inverse name

. so f(x) = x - 3.
so h(f(x)) = (x - 3) + 3 = x what we did is plug f(x) in for x which is the inverse of h(x). The answer is h(f(x)) =x.
Answer:
The absolute value of a number means the distance from 0. -5 is 5 units away from 0. So the absolute value of that -5 is 5. You cannot have negative distance, so it has to be positive.
Step-by-step explanation:
Answer:
The original price is $90.
Step-by-step explanation:
100% - 40% = 60%

y × 60 = 54 × 100
60y = 5400
60y ÷ 60 = 5400 ÷ 60
y = 90
Answer:
i think its b but im not sure
Step-by-step explanation:
If x² = 196, then we must do the inverse (square root) to find x. However, the square root of any positive number will always be ± (plus or minus).
That means you have to do:
√196 = x
x = <span>±14.
We can check this by doing:
14 </span>× 14 = 196
-14 × -14 = 196
Therefore the answer is B) -14, 14.
