Answer:

Step-by-step explanation:

What makes a function is if each input or x-value has EXACTLY one output or y-value.

a. is wrong because the x value 1, has both an output of 1 and 4

b. is wrong because -1 is repeated 4 times with all different outputs

c. is correct because each input has exactly one output. None of the x values repeat itself

d. is wrong because -1 has 2 outputs.

so this is what makes a function and what doesn't. Hope this helps!

Lisa is mailing a letter to a friend. Postage costs $0.32 for the first ounce and $0.23 for the additional ounce. How heavy can

Advocard [28]

Answer: 8.3 ounces

Step-by-step explanation:

simple, there's a flat fee for 1 ounce, then 23 cents for each ounce following.

so $2 - $0.32 = $1.68

1.67 / 0.23 = 7.3 ounces

7.3 ounces + 1 ounces (from the flat fee we subtracted)

which equals 8.3

8) A pyramid has a rectangluar base with length 12 km and width of 5 km. If the volume is 200

SashulF [63]

Hi there!

$\large\boxed{h = 10km}$

We know that the equation for the volume of a pyramid is:

V = 1/3(bh)

We know that:

V = 200 km³

b = 12 × 5 = 60 km²

We can plug these into the equation:

200 = 1/3(60)(h)

Simplify:

200 = 20h

Divide both sides by 20:

200/20 = 20h/20

h = 10 km

Assume the average cost of maintaining a dog is the same from month to month. After 55 months, the dog had cost you a total of $

Marizza181 [45]

Answer:

Originally, you will <em>pay</em> $95.75 for the dog.

Step-by-step explanation:

Given:

Maintenance cost of dog after 55 months = $5,468.50

Maintenance cost of dog after 82 months = $8,053.75

To Find:

How much did you pay for the dog originally = ?

Solution:

It is stated that the maintenance cost is same from month to month

Now 82 - 55 = 27 months

For 27 we have paid

$8,053.75 - $5,468.50

$2585.25

But one month the amount paid will be

$\frac{2585.25}{27}$
