Answer:
y=45x+25
y = total cost and x = number of months.
Your question is very confusing but x=8 so just plug in 8 where you see X
Answer:
A.) Max at x = 6 and Min at x = -6
Step-by-step explanation:
We say that f(x) has a relative (or local) maximum at x=c if f(x)≤f(c) f ( x ) ≤ f ( c ) for every x in some open interval around x=c . We say that f(x) has an absolute (or global) minimum at x=c if f(x)≥f(c) f ( x ) ≥ f ( c ) for every x in the domain we are working on.
Use the Pythagorean theorem.
If x is a hypotenuse, then we have:

If x is a leg, then we have:
