Answer:

Step-by-step explanation:

Taking the absolute value of anything makes it positive, so you know that the graph of |f(x)| must only have positive.

And since c is the only graph with no negative values c it must be the answer

Also if you compare it with f(x), c it flips the negative parts of f(x) to positive.

A bike shop rents bikes for $4.50 per hour, plus a $7.50 insurance charge. For how many hours can Peter rent a bike if he has $3

Mandarinka [93]

Answer:

With $30, Peter can afford 5 hours

Step-by-step explanation:

Given

Insurance Charge = $7.5

Charges = $4.5 per hour

Required

Determine the number of hours $30 can afford

First, we need to determine the equation.

<em>Total Charges = Charges per hour + Insurance Charge</em>

Substitute values for Charges per hour and Insurance Charge

Total Charges = 4.5 per hour + 7.5

Let the number of hours be n;

So,

Total Charges = 4.5n + 7.5

To calculate Peter's; substitute 30 for total charges

$30 = 4.5n + 7.5$

Subtract 7.5 from both sides

$4.5n = 30 - 7.5$

$4.5n = 22.5$

Divide both sides by 4.5

$n = \frac{22.5}{4.5}$

$n = 5$

Hence;

<em>With $30, Peter can afford 5 hours</em>

Several intervals can be combined into one region using the "set union" operation, ∪∪, which is represented as "u" in webwork. f

Write the set of points from -6 to 0 but excluding -4 and 0 as a union of intervals

First we take the interval -6 to 0. In that -4 and 0 are excluded.

So we split the interval -6 to 0.

Start with -6 and go up to -4. -4 is excluded so we break at -4. Also we use parenthesis for -4.

Interval becomes [-6,-4) . It says -6 included but -4 excluded.

Next interval starts at -4 and ends at 0. -4 and 0 are excluded so we use parenthesis not square brackets

(-4,0)

Now we take union of both intervals

[-6,-4) U (-4,0) --- Interval from -6 to 0 but excluding -4 and 0
