If
is the inverse of
, then by definition of inverse functions,

Given
, the inverse, if its exists, satisfies the equation above. Evaluate
at the inverse, we have

Solve for the inverse:



Given
, we do the same thing as before to find its inverse.

Answer:
k=57
Step-by-step explanation:
Multiply both sides by 5
k-2=55
Move the constant to the right-hand side and change its sign
k=55+2
k=57
Answer:
please don't delete
Step-by-step explanation:
ill give points back
$3/6 = .50 per orange
$2.40/3 = .80 per grapefruit
10(.50) + 11(.80) =
$5.00 + $8.80 = $13.80
Basically all you’re doing is plugging in the inputs to the equations and see if they’re correct.
5(3)+4(-3)=3 this proves to be true
2(3)-5(-3)=21 not 19
