To solve the equation -x - 3 = x2 – 2x-15, you
could graph of the following system.
y = -x - 3
y = x2 – 2x – 15
use the graph of this system to identify all
solutions of -x - 3 = x2 – 2x – 15.

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

What is the measure of angle z in this figure? enter your answer in the box. z = ° two intersection lines. all four angles formed by the intersecting lines are labeled. clockwise, the angles are labeled 43 degrees, x degrees, y degrees, and z degrees.

Which equation represents the function on the graph?
