Answer:
8
Step-by-step explanation:
4.5x+10<=50
4.5x<=50-10
4.5x<=40
x<=8.9
round down because can't go beyond 50
x=8 max
Parallel lines have the same slope.
So I plug in the -5 and -4
-4 = 1/2(-5) + b
-4 = -2.5 + b
b = -1.5
So I get y = 1/2x - 3/2
Answer:

Step-by-step explanation:

Y=f(X)
At y-intercept, X=0
f(X)= 0^3-18(0)^3+107(0)-210
= -210
