7) Marya sells custom signs. In January she sold B signs for $188. February she sold 13 signs for
$305.50, and in March, she sold 10 signs for $235. Is
this a proportional relationship? If so, write an
equation to represent this situation.

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
