The question has been kind enough to provide the solution to you! It suggest multiplying her sales by 0.3 to find 30% of the total, in order to find how much money she donated to charity. To put this into practice:

Let's solve by eliminating
x
. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
Add the two equations.
Divide by -11 to isolate
y
y= -2
Substitute
y
=
−
2
into either of the 2 equations, I'll just use the second one.
x = -1
One hundred thirty five 13%
It's the slope of the secant line to <em>f(x)</em> through the points (-3, <em>f</em> (-3)) and (9, <em>f</em> (9)),
It’s 360 degrees. The measure of one exterior angle is equal to 360 divided by the number of sides in the polygon
