4) Which step could be completed in order to prepare the system of equations below for the elimination method?

1st equation: 5x-3y=10
2nd equation: 8x+6y=15

A) Multiply the 1st equation by -2
B)Multiply the 2nd equation by 2
C)Multiply the 1st equation by 2
D)Multiply the 2nd equation by -2

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
