Answer:
m = - 3
Step-by-step explanation:
a³ + 27 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
a³ + 27
= a³ + 3³
= (a + 3)(a² - 3a + 9)
comparing a² - 3a + 9 to a² + ma + 9, then
m = - 3
Answer: C (AngleMRN and AngleNRO)
Step-by-step explanation:
A linear pair of angles is formed when two lines intersect. Two angles are linear if they are adjacent angles (angles next to each other) formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
AngleMRN and AngleNRO together is 180 degrees
I'm not very good at explaining but hope this helps ! :)
The equation formula is y - y1 = m(x-x1)
Using the first point for x1, y1:
Y +13 = m(x-15)
M is the slope which is the change in y over the change in x:
M = -11–13 / 16-15 = 2/1 = 2
The equation becomes y +13 =2(x+15)
The answer is:
He incorrectly wrote the slope in his equation. He should have written y+13=2(x−15).
