Answer:
- slope: cost per mile
- y-intercept: fixed base cost
Step-by-step explanation:
The y-intercept is the value of y when x=0. The problem statement tells you that x is the number of miles driven, and y is the rental cost.
When the number of miles driven is zero, the rental cost is ...
y = 2.25×0 +70
y = 70
The cost of renting the truck is $70 when it isn't driven anywhere. The y-intercept ($70) is the basic, fixed cost of truck rental.
__
If x=1 (1 mile driven), then 2.25 is added to the cost of the truck rental. The slope (2.25) is the cost per mile driven. (That mileage cost is added to the basic rental cost.)
Answer:
a(n) = -20 + 3(n - 1)
Step-by-step explanation:
a(n) = -20 + 3(n - 1)
Step-by-step explanation:
hope this helps. in the first part you set the problems equal to each other. in the second, you get rid of one letter, then solve.
Answer:
What the equation is telling us is that after opening for 1 hour 15 minutes, there were 28 visitors
Step-by-step explanation:
The function we are given is ;
V(1.25) = 28
what this mean is that the number of visitors in the museum after 1.25 hours of opening is 28
1.25 hours is same as 1 hour (0.25 * 60) minutes
What is in the bracket is trying to convert the 0.25 hours to minutes
Since 1 hour is 60 minutes, 0.25 will be (0.25 * 70)
Which is 1 hour 15 minutes
So after opening for 1 hour 15 minutes, the museum had 28 visitors
e=3.
So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
