Answer:
6 < x < 8 is decreasing
10 < x < 14 is neither
8 < x < 10 is increasing
4 < x < 6 is increasing
1 < x < 4 is decreasing
Step-by-step explanation:
just see where the line is going up or down
down is decreasing
up is increasing
It's one of the ways to count it:
3/4 (n + 3) = 9
3/4n + 3/4 * 3 = 9
3/4n + 9/4 = 9
3/4n + 2 1/4 = 9 / - 2 1/4 (both sides)
3/4n = 6 3/4 / : 3/4 (both sides)
n = 9
Answer:
Fewer will be sold
Step-by-step explanation: From the start of the graph when the price is high the number sold is low.
Answer:
the answer is a^20
Step-by-step explanation:
(a^4)^5
a^4×5
a^20
A = L * W
A = 54
L = 2W + 3
54 = W(2W + 3)
54 = 2W^2 + 3W
2W^2 + 3W - 54 = 0
(2W - 9)(W + 6) = 0
2W - 9 = 0
2W = 9
W = 9/2
W = 4.5 <== width
W + 6 = 0
W = -6....it wont be this one because it is negative
L = 2W + 3
L = 2(4.5) + 3
L = 9 + 3
L = 12 <==length
