Camille and Hiroki have decided to start walking for exercise. Camille is going to walk 777 miles the first day and 333 miles ea
labwork [276]

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

Can I get some help I think I did this wrong and I guessed :/

You'll want to first simplify the expression (2t-8)- \frac{1}{2} (9-4t)+ \frac{5}{2}}.

To do that, first distribute the - \frac{1}{2}:

(2t-8)- \frac{1}{2} (9-4t)+ \frac{5}{2}}
2t-8- \frac{9}{2} +2x+ \frac{5}{2}

From there, you may just combine like terms:

2t-8- \frac{9}{2} +2t+ \frac{5}{2}
4t-8- \frac{9}{2} + \frac{5}{2}
4t-8- \frac{4}{2}
4t-8-2
4t-10

Answer:
D. 4t - 10

Function g can be thought as scaled version of f(x)=x^2
Genrish500 [490]

Answer:

g(x)=-\frac{1}{4} x^2

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.
