Question

campbell_st · Answer

its concave left

campbell_st · Answer

and symmetrical about the y axis

anonymous · Answer

Thank you :)

anonymous · Answer

notice that if the equation was x = y^2, x will ALWAYS be positve no matter what y is.
so you equation is x = -y^2 means x will always be negative.  so it opens left.

anonymous · Answer

can you guys solve this by graphing?? y = -x + 4
(x - 3)2 + y2 = 25

anonymous · Answer

y = -x + 4
(x - 3)2 + y2 = 25

campbell_st · Answer

yep... you need to solve this by substitution 

so take the 1st equation and substitute it into the 2nd equation 

$$(x - 3)^2 + (4 - x)^2 = 25$$

1st simplify the equation and the solve for x

when you get x, there are 2 values...I think

substitute into the 1st equation to find y

it says to solve this system by graphing because I need the coordinates lol
