This is the first quadrant graph of an even function. On a coordinate plane, a function has four connecting parts. The first part is a curve facing up that goes from (0, 0) to (2.5, 9). The second part is a straight line with negative slope from (2.5, 9) to (7, 7). The third part is a straight and horizontal line from (7, 7) to (9, 7). The fourth part is a curve facing down that goes from (9, 7) through (12, 4).
The function is
✔ constant
for –9 < x < –7.
The function is increasing for
.
The point
lies on the graph of the function.

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°.

lr = 24

step-by-step explanation:

note that p is the midpoint of lr. to find the measurement of lr, set the equation:

lr = lp + pr

plug in the corresponding numbers to the corresponding variables:

lr = (15) + (9)

simplify:

lr = 24

24 is your measurement of lr.
