Question

find the solution(s) to the system of equations. select all that apply y=x^2 - 4 y= 2x-5 - 2 A. (-5-0) B.(1,-3)C.(-2,0)D.(2,0)

Answer 1

B.(1,-3)

Explanation:

Given in the question two equation

Equation1

y = x² - 4

Equation2

y = 2x - 5

Substitute y with 2x-5 in equation2

x² - 4 = 2x - 5

x² - 2x + 1 = 0

(x-1)(x-1)=0

x = 1

plug value of x in any equation

y = 2(1)- 5

y = -3
