Answer:
(16,90)
Step-by-step explanation:
I think you mean that the add has 16 lines in it. Is that correct? If it is then you start by putting 16 in for x.
y = 5*16 + 10
y = 80 + 10
y = 90
So x = 16
and y = 90
You write that as an ordered pair like this: (16,90)
Answer:
the slope is 1/2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Volume varies directly with the square of the radius, so:
V = k r²
When V = 80, r = 4.
80 = k (4)²
k = 5
V = 5r²
When r = 3:
V = 5 (3)²
V = 45
The flow is 45 L/min.
