A

Step-by-step explanation:

I've forgotten the exponent rules for exponent operations, but one way to do this is to find the value of the expression given (2^-5 * 2^7)^-3 (which is equal to 0.015625) using a calculator, then use your calculator to find which answer choice is equal to the expression given AKA 0.015625. I did this and got A, but you should probably still look up exponent rules for future reference. Trust me, this question is actually WAY easier than what it probably looks like to you, as long as you know the exponent rules. :)

Give me Brainliest and have a great day! :)

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!
