Step-by-step explanation:
range is y values
What do you mean by that?
the slope would be the change in Y over the change in X,
-7-1= -8, 3-(-1)= 4, -8/4 or -2 is the slope
Answer:
13 + 14 + 15
Step-by-step explanation:
n + (n + 1) + (n +2) =42
n + n + n + 1 + 2 = 42
3n + 3 = 42
(subtract 3 from both sides)
3n = 39
(divide both sides by 3)
n = 13
(solve)
n + (n + 1) + (n +2) =42
13 + (13 + 1) + (13 + 2) = 42
13 + (14) + (15) = 42
13, 14, 15
