Answer:
-5.2
Step-by-step explanation:
18 - 23.2 = -5.2
x = 2
8x + 5 = 3x + 15
8x - 3x + 5 = 3x - 3x + 15
5x + 5 = 15
5x + 5 - 5 = 15 - 5
5x = 10
5x / 5 = 10 / 5
Cross multiply and get:
L = 5w
L = 5w/
W = L/5
Mean
Since 360 is such a greater amount of time than the previous ones, it will greatly affect the mean.
the vertex is (-1,4)
