Answer:
(a) This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Step-by-step explanation:
The equation of direct variation is ...
y = kx
for some constant k. Here, we have x in hours and y in dollars. We can see if k is constant for the values given in the table.
__
<h3>constant of variation</h3>
Solving the direct variation formula for k, we have ...
k = y/x
Using the table values, we can see if this is constant:
k = dollars/hour = 10/2 = 20/4 = 30/6 = 40/8 = 5
The "rate of change" is constant at $5 per hour.
The function represents direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
She ran 1 2/4 more miles, or 1 1/2 or 1.5 miles. I hope this helps!
Answer:
1(-4)
Step-by-step explanation:
I think it's 1(-4)
since it's moving 1 number over, four times. and if you multiply, the answer -4.
I'm pretty sure this is the answer.
4.8 by 2.4 inches because 120 divided by 25 is 4.8 and 60 divided by 25 is 2.4
