What are the solutions to the following system of equations? y = x2 + 12x + 30 8x − y = 10 (2 points) (−4, −2) and (2, 5) (−2, −4) and (2, 5) (−2, −4) and (5, 2) No real solutions

No real solution

Step-by-step explanation:

Given

Required

Find x and y

Make y the subject of formula in

Subtract 10 from both sides

Substitute 8x - 10 for y in

Subtract (8x - 10) from both sides

Collect like terms

At this point, we have a quadratic equation;

First, we'll check if the quadratic equation has real solution using:

Where a = 1; b = 4 and c= 40

Because the value of d is negative, then we can conclude that the solution has no real solution

x = -2

y = 848
