Answer:
100
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Use the slope formula:
m = (y2 - y1) / (x2 - x1)
m = (-3 - 2) / (5 - 3)
m = -5/2
Okay. So you can go 440 miles on 10 miles of gas. That’s 44 miles for 1 gallon of gas. For 60 miles of gas, you have to do 440 * 6. When you do that, your product should be 2,640. You can drive 2,640 miles on 69 gallons of gas and 44 miles per gallon of gas.
The two variables that we should use are:
- x = number of minutes that the call lasted.
- y = cost of that call.
<h3>
What variables should we use?</h3>
Here we want to study a relation between the cost per call as the function of the minutes that the call lasted.
So, we need to use two variables, x will be the number of minutes that call lasted, this is the independent variable.
And the variable that depends on that should be the cost of the call, let's say, y is the cost of the call.
These are the two variables that we need to model the situation:
y = f(x)
There says:
<em>"The cost of the call is a </em><em>function </em><em>of the number of minutes that the call lasted".</em>
