Sara and Meg buy an equal number of comic books every month. The following equation shows the number of comic books, y, that Sara has after x months: y = 2x + 15

The following graph shows the number of comic books, y, that Meg has after x months:

Graph shows Months on x axis and Number of Comic Books on y axis. The scale on x axis is shown from 0 to 5 at increments of 1. The scale on y axis is shown from 0 to 28 at increments of 4. The title of the graph is Megs Comic Books. A straight line is shown which joins the ordered pair 0, 12 and 4, 28

After 2 months, how many more comic books does Meg have than Sara?

1
3
8
10

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

answer is  

c.

56
