The cost of fixing errors in a computer program is related to the time spent developing the program by the equation y = 4x - 2,000x + 8,000, where x = the
time in hours and y = the cost in dollars. Which best describes the meaning of the
vertex of the parabola with that equation?
The cost reaches a maximum when 500 hours are spent developing the program.
The cost reaches a minimum when 500 hours are spent developing the program.
The cost reaches a minimum when 250 hours are spent developing the program.
The cost reaches a maximum when 250 hours are spent developing the program.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
