Answer:
The inverse is 1/2x -1/2
Step-by-step explanation:
f(x) = 2x+1
y = 2x+1
Exchange x and y
x = 2y+1
Solve for y
Subtract 1
x-1 = 2y+1-1
x-1 =2y
Divide by 2
x/2 -1/2 = 2y/2
1/2x -1/2 = y
The inverse is 1/2x -1/2
Answer:
8x+12
Step-by-step explanation:
We know that squares have equal sides. To calculate perimeter, just add up all of the 4 sides.
2x+3+2x+3+2x=3+2x+3
Add like terms:
8x+12
You could also multiply by four:
4(2x+3)
Use distributive property:
8x+12
