Answer 1

y = x^2 - 7x - 5

y = -2x + 19

Subtract:

y-y = x^2 - 7x - 5 - (-2x + 19)

Simplify:

o = x^2 - 5x - 24

Solve the polynomial by finding two numbers when added together equal -5 and when multiplied by each other equal -24

x = -3 and x = 8

Now replace x in the first equation with -3 and solve for y, then replace x with 8 and solve:

y = x^2 -7x -5: y = -3^2 - 7(-3) - 5 = 9 + 21 - 5 = 25

y = 8^2 - 7(8) -5 = 3

The answers are (8,3) and (-3,25)
