The solution set for all real numbers x such that 2x + 3 < 19 and 2x − 3 ≤ -7 is ( _ , _ ) note: if needed, type “-infinity” for -∞ and “infinity” for ∞. nextreset

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!
