For which intervals below is the average rate of change of m(x) = -5x-3 less than -25? interval a 3 ≤ x ≤ 5 b 4 ≤ x ≤ 5 c 4 ≤ x ≤ 6 interval a only interval c only intervals a and b only intervals b and c only

idk i would have to be there to under stand it

idk i would have to be there to under stand it

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

no one knows lol
