What is the product of (x - 9) and (2x - 7)

Step-by-step explanation:

You have to multiply both terms from the first one by both term in the second on, it'll look like this:

Once you combine like terms it'll be the final

You can use foiling to get any other questions like this:

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)
