Answer:
1/4x -3
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y =4x+12
Exchange x and y
x = 4y+12
Solve for y
Subtract 12 from each side
x-12 = 4y+12-12
x-12 = 4y
Divide by 4
(x-12)/4 = 4y/4
The inverse is
1/4x -3
Answer:
P = 108cm
A = 486 cm^2
Step-by-step explanation:
To find the perimeter add up all the side
P = 36+27+ 45 =108 cm
The area is
A = 1/2 bh
A = 1/2( 27)*36
A = 486 cm^2
1. 45/6 = 7.5
7.5*10 = 75
So the penguin walks 75 ft in 45 seconds.
2. 45/10 = 4.5
4.5*6 = 27
The penguin takes 27 seconds to walk 45 ft.
