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)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
