@retirEEd help?

retireed · Answer

Does the first equation start with "x squared" ?

anonymous · Answer

yes

retireed · Answer

Okay thanks let solve it first so I know what to do.

anonymous · Answer

How would I solve it?

phi · Answer

you could graph both equations and see where they cross

retireed · Answer

First I would set  the two equation equal to each other by eliminating the y

phi · Answer

or,  use the 2nd equation in the form
y= -8x+20
and replace y in the first equation with -8x+20

retireed · Answer

What phi said.

ohhh I understand now thank you :)
