Play machine can make 56 parts and 4 hours. it can also make 70 parts in 5 hours. write an expression that represents the number of parts of machine can make in the time in hours. predict how many parts of machine can make in 9 hours, 30 minutes.

i believe that the slope of the line is -5

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

b. f(x) = –√x + 3this is the correct answer
