Answer:

No she doesn´t.

Step-by-step explanation:

So in order to solve this you just have to create an inequality, x is the number of bills that ANdrea has so if she has enough bills she could buy the pair of shoes:

5x-25=y

If y>0 then she could buy her shoes:

5x-25=y

5(4)-25=y

y=-5

Since -5 is not greater than 0 then she can´t afford the pair of shoes.

Answer:

25 months

Step-by-step explanation:

when the rent, y = 0, we have,

y = -200.22x + 5014.20

y = 0

0 = -200.22x + 5014.20

200.22x = 5014.20

x = 5014.20 ÷ 200.22

x = 25.0434

x = 25(appx.)

Sorry, I don't know what you mean by interpolation and extrapolation:(

Pizza Paradise offers 4 types of crust, 10 toppings, and 8 kinds of cheese for the mega calzone. How many different mega calzone
Bumek [7]

Answer:

26880 ways

<em></em>

Step-by-step explanation:

Given

Crust = 4

Toppings = 10

Cheese = 8

Required

Determine the number of ways 3 toppings and 3 cheese can be selected

The number of crusts to be selected was not stated. So, I'll assume 1 crust to be selected from 4.

This can be done in ^4C_1 ways

For the toppings:

3 can be selected from 10 in ^{10}C_3 ways

For the cheeses:

3 can be selected from 8 in ^{8}C_3 ways

Total number of selection is:

Total = ^4C_1 * ^{10}C_3 * ^{8}C_3

Apply combination formula:

Total = \frac{4!}{(4-1)!1!} * \frac{10!}{(10-3)!3!} * \frac{8!}{(8-3)!3!}

Total = \frac{4!}{3!1!} * \frac{10!}{7!3!} * \frac{8!}{5!3!}

Total = \frac{4*3!}{3!*1} * \frac{10*9*8*7!}{7!*3*2*1} * \frac{8*7*6*5!}{5!*3*2*1}

Total = \frac{4}{1} * \frac{10*9*8}{3*2*1} * \frac{8*7*6}{3*2*1}

Total = 4 * \frac{720}{6} * \frac{336}{6}

Total = 4 * 120* 56

Total = 26880

<em>Hence, there are 26880 ways</em>

The equation is y = -4x - 2. the equation will be in the form y = mx + b because this is a linear equation. the m is the slope, and this can be found by counting the units between points as rise over run. you can use the first and second points to do this. the rise is -4, and the run is 1, so the slope is -4. the third point is the y-intercept and that is where you find the b value. the coordinates are (0, -2), so the b value is -2.
