Sean promotes certain brands on his social media page for compensation. His monthly profit can be modeled using the quadratic function p(x)=-0.00425x^2+7x-1000, where p(x) is the amount of profit earned over x number of days. The graph of the function is shown. Use the graph to find the zeros of the function and interpret them in context.

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
