Answer: You did not include the answer to the equation so 48x+72 is the closet I could get to finding the expression
Hope this Helped!!!
Answer:
13.92$
Step-by-step explanation:
13.26 times .05 (sales tax)
.66 + 13.26 = 13.92
C=1500+4x where x is cds, C is cost
R=10x where R is revenue
then, P=R-C
P=10x-1500-4x
P=6x-1500
set P=0
1500=6x
x=250
check, C=1500+4*250, R=10*250
C=250, R=250
They need to sell 250 cds before they make profit

What's The Fixed Point? Well, Let's Assume X=0, this is our point.

OR

I'm unaware of the nature of the question, so here are some different ways a fixed point is found based on the merits of the question.
Answer:
f(7) = -23
Step-by-step explanation:
f(x) = -3x - 2
f(7) = -3(7) - 2
f(7) = -21 - 2 = -23
