Solve. (If there is no solution, enter NO SOLUTION.)
y= x^2-x-4
y=x+4
(x, y) = ( , ) (smaller x-value)
(x, y) = ( , ) (larger x-value)
x^2 + y^2 =10
x+y=4
(x,y)= ( , ) smaller value
(x,y)= ( , ) larger value
I'll do the first. If you get stuck on #2, come on back with whatcha got.
y = x+4, so
x+4 = x^2-x-4
x^2-2x-8 = 0
(x-4)(x+2) = 0
x = 4 or -2
