Answer:

$226

Step-by-step explanation:

1. define the variable x

x = # of days to rent the carpet cleaner

2. substitute x for 7 days

c(7) = 30(7) + 16

3. solve

c(7) = 210 + 16

c(7) = 226

For 7 days, Rhonda will have to rent the carpet cleaner for $226.

Natalija [7]

Answer:

$L = 30\\R = 21\\M = 42$

Step-by-step explanation:

Let's assign each person a variable using the first letter of his/her name.

Then we get the following equations based on the information given:

$L + M + R = 93\\L - 9 = R\\M = 2R$

Then we can use substitution:

$L + M + R = 93\\L + (2R) + R = 93\\L + 3R = 93$

Rearrange the second equation:

$L - R = 9$

Multiple the equation by 3:

$3L - 3R = 27$

Combine the equations to solve for a single variable (L):

$L + 3L = 4L\\3R - 3R = 0\\93 + 27 = 120$

Then we have a new equation:

$4L = 120\\L = 30$

Use substitution to get the rest:

$L - 9 = R\\(30) - 9 = R\\R = 21\\\\M = 2R\\M = 2(21)\\M = 42$

which is a graph of f(x)=5x-2/x+2with any vertical or horizontal asympototes indicated by the dash lines?

Dahasolnce [82]

Answer:

See attachment

Step-by-step explanation:

The given function is $f(x)=\frac{5x-2}{x+2}$ .

This rational function has a vertical asymptote at where the denominator is zero.

The denominator $x+2=0$ when $x=-2$

There is vertical asymptote at $x=-2$

The horizontal asymptote for this rational function is given by the ratio of the leading coefficient of the numerator to the leading coefficient of the denominator.

$y=\frac{5}{1}$

The horizontal asymptote is $y=5$

The graph of this rational function is shown in the attachment

Describe a time when someone around you made a decision based on authority of someone else?

dalvyx [7]

There was a time that a friend of mine got to a decision because the leader of the group said so (it was a group project). Although it was clear that he did not want to comply to the decision, he made it because it was what the leader said so.
