How many solutions does 3x+4y=6 -3x-4y=-5 have.

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?

Which of these tables represents a non-linear function?

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
