What do the following two equations represent?
-4x - 5y = -4

4x + 5y = 4
(parallel, perpendicular, equal, or none of the above)

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

If f(x)=3 over x+2 - square root x-3 then f(7)=
