(25 pts) find −3a^2 − b^3 + 3c^2 − 2b^3 if a = 2, b = −1, and c = 3. *

Substitute the values in the expression:-

= -3*2^2 - (-1)^3 + 3*3^2 - 2*(-1)^3

= -12 - (-1) + 27 - 2*-1

= -12 + 1 + 27 + 2

= 18 (answer)

29 mil

step-by-step explanation:

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

answer:

f(5/2) = 10/3

i hope this you!
