Help?

Answer 1

find the solutions to the system
y=x^2+8x+2
y=x+4


a. (-2,-10) and (1,11)
b. (2,10) and (-1,-11)
c.(-2,-34) and (1,11)
d.No solutions

Answer 2

using 'y=x+4' you can substitute x+4 into y=x^2+8x+2 for y and solve for x.

Answer 3

i dont understand..

Answer 4

What he means is that in the first equation replace "y" with "x+4"!

Answer 5

So x+4=x^2+8x+2?

Answer 6

Exactly!

Answer 7

subtract 2 from 4 and get x+2=x^2+8x?

Answer 8

i would subtract x from both sides and then subtract 4 from both sides.
tell me what is the result of your subtractions after you do this.

Answer 9

Whats x- x^2?

Answer 10

I am going back on the x+4=x^2+8x+2

Answer 11

x+4- (x+4) =x^2+8x+2 - (x+4)

Answer 12

im lost. now.

Answer 13

x+4-(x+4)= x^2+8x+2-(x+4) IS 0=x^2+7x-2.

Answer 14

Is it (-2,-10) and (1,11)
