Which ordered pair is the solution to the system of lunear equations y = 5x + 8 and y = -4x - 1

The order paired (-1 , 3) is the solution

Step-by-step explanation:

∵ y = 5x + 8

∵ y = -4x - 1

∴ 5x + 8 = -4x - 1

∴ 5x + 4x = -1 - 8

∴ 9x = -9

∴ x = -1

Substitute x in any of the two equation to find the value of y

∴ y = 5(-1) + 8 = -5 + 8 = 3

∴ The ordered pair is ( -1 , 3)

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 !
