5x = 2x-15
3x = -15
x = -5

substitute x = -5 into one of your equations
so y = 5x becomes y = 5 x -5
y= -25

x=-5 and y=-25

A quadratic equation has the solutions x- -5 and x=4 What are the x-intercepts of the graph of the function?
DedPeter [7]
Answer:
(-4, 0) and (1, 0)

Step-by-step explanation:
"Solutions" in this case have the same numeric values as do "x-intercepts."
If x = -4 is a "solution" of this quadratic equation, then (-4, 0) is the corresponding x-intercept. Likewise, if x = 1 is a solution, then (1, 0) is the corresponding x-intercept.
