The equation represents an ellipse. which lines represent the approximate directrices of the ellipse? round to the nearest tenth. x = −8.6 and x = 8.6 x = −6.6 and x = 10.6 y = −8.6 and y = 8.6 y = −6.6 and y = 10.6

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!
