a. 23.6 yd
b. 7.5 yd
c. 47.1 yd
d. 94.2 yd

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

Which is the focus of a parabola with equation y2=4x

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
