Answer: 7 days
Step-by-step explanation:
Camille and Hiroki have decided to start walking for exercise. Camille is going to walk 7 miles the first day and 3 miles each day after that. Hiroki is too busy to walk on the first 2 days, so he decides to walk 5 miles each day until he has walked the same number of miles as Camille.
Camille will walk x days, so: 7 + 3(x-1) miles
Hiroki will walk the same miles, but 2 days less so: 5(x-2)
same amount of miles:
5(x-2) = 7 + 3(x-1)
5x - 10 = 7 + 3x - 3
5x - 3x = 10 + 7 - 3
2x = 14
x = 7
If Camille and Hiroki will have walked the same number of miles, how many days will Camille have walked?
Camille will have walked 7 days.
A customer that uses an internet plan that costs $10 per month is expected to give a customer rating of 6
<h3>How to determine the customer rating?</h3>
We start by calculating the regression equation of the table of values using a graphing calculator.
Using the graphing calculator, we have:
y = 0.04x + 5.75
When the cost is $10 per month, it means that
x = 10
So, we have:
y = 0.04 * 10 + 5.75
Evaluate
y = 6.15
Approximate
y = 6
Hence, a customer that uses an internet plan that costs $10 per month is expected to give a customer rating of 6

You'll want to first simplify the expression
.
To do that, first distribute the
:
From there, you may just combine like terms:
Answer:
D. 4t - 10
Answer:
Step-by-step explanation:
The graph is reflected against the x-axis, meaning it is negative
Next, we see that the graph is stretched out, therefor we have a fraction
The fraction is -1/4
You can check by inputting the x values into the x variable.
