Answer:
Step-by-step explanation:
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Answer:
9h + 40
Step-by-step explanation:
You use 9h, because you don't know how many hours Jill worked, she already had 40$ so 40 is the constant.
A=TX
Rewrite it
Tx=a
Divide t both sides to get x alone
Tx/t=a/t
Solve
X= a/t
The answer would be neither
The equations both don't have slope so parallel is out, and in order to be perpendicular, they must cross at the 90 degree angel which they are not . So the answer would be neither
False. You can use any number of values and any number for those values. You will always show the y value to be true.
