Answer:
no
Step-by-step explanation:
To be a function, the x values must correspond to one and only one y value.
In the coordinates given, (0.3, 0.6) and (0.3, 0.7) have the same x- value.
That means that they cannot be a function.

Step-by-step explanation:
FOIL
(1/2)h*B1+ (1/2)h*B2=A
subtract the B2 term
(1/2)h*B1 = A- (1/2)h*B2
multiply by 2
h*B1 = 2A - h*B2
divide by h

Answer:
8 hours
Step-by-step explanation:
basic equation
Q (flow rate) = V (volume)/ t (time)
so to find the time we just rearrange the equation and become
t = V/Q
V of cylinder
V = πr²T
and r (radius) = ½ diameter
V = 3.14 x 5² x 1.4
V = 109.9 m³
if the Q is 13 m³/hour then
t = 109.9/13 = 8.453 hours
round to nearest hour = 8 hours
Answer:
A. $18.54
Step-by-step explanation:
laptop cost x commission = money made
309 x 0.06 = 18.54
Let's look at each pair and change it so the first one in the pair will be what the second one will be converted to.
8,600 mg = 86,000 mg; So now, the first one is not equivalent.
2,500 g = 250,000 g; Not that one either.
3.4 kg = 3.4 kg; This one is correct. We can check by checking the last pair.
480 g = .0048 g; Nope.
So 3.4 kg, 3400 g would be the correct answer.
