Zoey is playing an arcade game. She needs to earn more than 850 points to beat its high score. So far, she has 75 points. She earns 25 points each time she finishes a level. Write an inequality to find the number of levels, L, that Zoey still needs to beat to break the record.

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?

Use the x-intercept method to find all real solutions of the equation. -9x^3-7x^2-96x+36=3x^3+x^2-3x+8

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles
