Step-by-step explanation:

Car,en invested her saving in two investment funds.The $18000 that she invented in Fund A returned a 6 percent profit.

$18,000 × 6%

The amount that she invented in fund B returned a 2 percent profit.

= x × 2%

if both fund together returned a 5 percent profit

($18,000 + x ) 5%

Equation

18000 × 0.06 + x × 0.02 = (18000 + x) × 0.05

step-by-step explanation:

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 !
