(x-9)(x+7)=0
x-9=0 or x+7=0
x=9 or x=-7

Answer:
the number of coats in the coat check will most likely decrease if the temperatures decrease.
Step-by-step explanation:
Im guessing this answer: Number of coats in the coat check will decrease because the graph shows negative association
But it could also be this answer: Number of coats in the coat check will decrease because the graph shows positive association
I think the graph shows a negative association because when the temperature goes down, the coat check goes down as well
Answer:

Answer:
x = 48°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (90 + 42)° = 180° - 132° = 48°
Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.
