If y = 3x + 5 and z x2 + 2x – 5, what is yz?

A. 2x3 + 11x2 + 5x – 25
B. 3x3 + 13x2 + 10x – 25
C. 3x3 + 16x2 + 10x – 25
D. 3x3 + 11x2 – 5x – 25

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
