11. Mike is a veterinarian. He is placing a 9-line classified ad for an assistant. The following piecewise function gives the price of an
X-line ad.
45
when <3
45 + 9x - 3) when x > 3
a. Find the difference between the cost of a 2-line ad and the cost of
a 3-line ad
b. Find the cost of a 10-line ad.
6. Find the cost of an 11-line ad.
d. Can you find the difference between the cost of a 15-line ad
and a 17.line ad, without finding out the cost of each ad first?
Explain

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
