<u><em>Answer:</em></u>
D. f⁻¹(x) = 2x + 10
<u><em>Explanation:</em></u>
<u>The given is:</u>

<u>To find the inverse, follow the below procedures:</u>
<u>1- Convert f(x) to y. </u>
<u>This will give:</u>

<u>2- Swap the x and y variables.</u>
<u>This will give:</u>

<u>3- Solve for y.</u>
<u>This will give:</u>

<u>4- Replace the y in the above step with f⁻¹(x).</u>
<u>This will give us:</u>
f⁻¹(x) = 2x + 10

Answer:
Step-by-step explanation:
Start from left one first
12x & 70
Area as Sum= 12x+70
Area as Product = 12(x+5)
Right side
X & 4
Area as Sum= 5X+20
Area as Product = 5(X+4)
14+5x=3(-x+3)-11
14+5x=-3x+9-11
14+5x=-3x-2
add 2 to both sides
16+5x=-3x
subtract 5x from both sides
16=-8x
divide both sides by -8
-2=x
