The solution to the piecewise problem given are :
- Difference in cost of 2 and 3 line ad is 0
- Cost of 10-line ad = $108
- Cost of 11 - line ad = $117
From the piecewice function given :
x = number of lines in ad
The cost of ad when x ≤ 3 is 45
Hence, the cost of a 2 and 3 line ad is 45, Therefore, the difference is 0 ;
The cost of a 10 - line ad ;
x = 10
Cost = 45 + 9(x - 3)
Cost = 45 + 9(10 - 3)
Cost = 45 + 9(7)
Cost = 45 + 63 = 108
The cost of a 11 - line ad ;
x = 11
Cost = 45 + 9(x - 3)
Cost = 45 + 9(11 - 3)
Cost = 45 + 9(8)
Cost = 45 + 72 = 117
Hence, the solution to the piecewise related questions.

leading coefficient is - 2
Answer:
y=5/4x-11
Step-by-step explanation:
tenemos un punto (4,-6) y una pendiente equal a 5/4.
usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)
porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:
y=5/4x+b
en el punto, x=4, y=-6
podemos sustituir los números en la fómula para resolver b
-6=4(5/4)+b
-6=5+b
-11=b
entonces,
la ecuación de la recta es y=5/4x-11
