Question

FAN AND MEDAL
What are the solutions to the following system of equations? Select the correct answer below.

y = x^2 − 2x + 4
8x + y = 20

Answer 1

The answer choices are

(2, 84) and (−8, 4)

(−8, 2) and (84, 4)

(2, 4) and (−8, 84)

(4, −8) and (84, 2)

Answer 2

Do you want the steps to solve this?

Answer 3

Plug in y = x^2 - 2x + 4 into the lower equation and there solve for x.
Then plug that x into the upper equation

Answer 4

How would that work out?

Answer 5

By plugging upper equation into lower (just substituting y), you'll have
8x + x^2 -2x + 4 = 20

Answer 6

That's a quadratic equation, which will give you two answers for x. Then use these answers in the upper equation to solve for y.

Answer 7

Does that make sense?

Answer 8

a little bit yeah

Answer 9

its 4 AM and i have little to no idea what I'm doing, i reallly need to get this test done and this is the last question

Answer 10

i can sorta understand all this but having brain troubles

Answer 11
