Three medium pizzas cost $10.50. How much does it cost to buy 10 medium pizzas?
olga nikolaevna [1]
Hello! First off, we can find the unit rate on what it would cost per pizza. Divide the total amount by the number of pizzas. 10.50/3 is 3.5. It costs $3.50 per medium pizza. Now, we can multiply that amount by 10 to get the amount for 10 pizzas. 3.5 * 10 is 35. There. It costs $35 to buy 10 medium pizzas.

Answer:

Not a function.

Does not pass vertical line test.

B.

Step-by-step explanation:

Something called a vertical line test is used to determine if a relation that has been graphed is a function or not.

We say if it passes then it is a function.

It will pass if you are able to draw infinitely many vertical lines covering the whole graph and each vertical line either touches your relation once or none.  

If a single vertical line that you draw touches more than once, then it isn't a function.

When I say draw, I don't mean you should physically do it, but more so imagine it.

Now this particular relation is not a function because I can find a vertical line that touches more than once.  Take the vertical line x=5 for example.

It will touch at (5,-6) and (5,6). You cannot have an x assigned to more than one y.

<h3>You have the correct answer</h3><h3>Interest rate = 21.5%</h3>

===============================================

Work Shown:

i = P*r*t .... simple interest formula

i = simple interest

i = 2075-1000 = 1075

P = 1000 = amount borrowed (principal)

r = unknown interest rate

t = 5 = time in years

So,

i = P*r*t

1075 = 1000*r*5

1075 = 5000r

5000r = 1075

r = 1075/5000

r = 0.215

r = 21.5%
