8x − y = 10

a) (−4, −2) and (2, 5)

b) (−2, −4) and (2, 5)

c) (−2, −4) and (5, 2)

d) No Real Solution

Answer 2

i got c

Answer 3

it is c

Answer 4

how do you know?

Answer 5

thks for medal

Answer 6

I don't get C

if C was correct....lets plug them in...the answers for C are (-2, -4) and (5,2)

y = x^2 + 12x + 30
8x − y = 10

that first equation will become

-4 = (-2)^2 + 12(-2) + 30
-4 = 4 - 24 + 30
-4 = -20 + 30
-4 = 10

?? no, that is incorrect
