Find the unknown value in the proportion: 7⁄15 = x⁄75

The product of two negative rational numbers is always zero sometimes zero never zero

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
