The slope of the line that best models the situation is the rate of change in the level of the pool. From the given problem, the rate of change is 0.5 / day. Thus, the slope is 0.5. The answer to this item is letter B.
Answer:
x=6
Step-by-step explanation:
6(2x -11) 15 =21
6 × 2x = 12x
6 × -11 = -66
12x -66 + 15 = 21
-66 + 15 = -51
12x -51 = 21
-51 + 51 = 0
21 + 51 = 72
12x = 72
12x ÷ 2 = 0
72 ÷ 12 = 6
x = 6
Answer: 7 ft/yr
Step-by-step explanation:
The percent increase is 12.5%, 800 multiplied by 0.125 equals 100 and 100+800=900.
W= l - 5 where w = width and l = length
area = 84 = l*w = l(l-5)
l(l-5) = 84
l^2 - 5l - 84 = 0
(l - 12)(l + 7) = 0
l = 12
length = 12 and width = 7
