Question

.

Answer 1

where is this from

Answer 2

like school or online school or u just wanna know?

Answer 3

let's look at the second equation

8x + y = 20

we can solve for y to get:

y = 20 - 8x

then we can look at our first equation:
y = x^2 - 2x + 4

we can set them equal to each other to get:

20 - 8x = x^2 - 2x + 4

know where to go from here?

Answer 4

keep going

subtract 20 from each side and factor

Answer 5

yes, so keep going

x^2 + 6x - 16 = (x+8)(x-2)

so x = -8 and x = 2

now calculate the matching y values
