Mathematics

Answer:

y intercept is 18

Step-by-step explanation:

It is given that

Monthly rent for phone service = $18

charges for each long distance minute = $ 0.07

Let us assume number of minutes used = x

also let us represent total cost by  y

So the total cost = ( charges per minute )(number of minutes) + monthly rent

y= 0.07x+18

now we compare this equation with y=mx+b

where m is the slope and b is y intercept

so we have b= 18

hence y intercept is 18

Pamela and her friend Nicole are each baking apple pies and tarts for a bake sale, using the same recipes. Pamela baked 5 apple
valentina_108 [34]

Answer:

Each apple pie requires 8 apples, and each apple tart requires 4 apples.

Step-by-step explanation:

We see that both Pamela and Nicole bake the same amount of apple pies, but different amounts of apple tarts. Because of this, we can subtract the two to try to figure out the amount of apples for each apple tart. We subtract 68 from 76, giving us 8. Nicole baked 9 apple tarts, while Pamela baked 7, and 9-7=2. So we can bake two apple tarts with 8 apples, so one apple tart requires 4 apples (we divide by 2). Now that we know the amount of apples per each apple tart, we multiply 7 apple tarts that Pamela made by 4 apples, giving us 28. We subtract that from the total amount of apples Pamela used, which was 68, giving us 40. From this we can deduct that 5 apple pies need 40 apples, and we divide by 5, giving us 1 apple pie requires 8 apples.

If you go out to eat with friends and your meal was $ 72.50 , there is 6.75 % sales tax and you should tip the waiter 15 % . How
Ugo [173]

Answer:

divide this amount ($88.26875) by the number of people

Step-by-step explanation:

6.75% of $72.50 is 4.89375

15% of $72.50 is 10.875

72.50 + 4.89375 + 10.875 = 88.26875

divide this amount (88.26875) by the number of people

A Find the slope of the graph using the
Elodia [21]

Answer: 2

Step-by-step explanation:

To find the slope, we use the formula m=\frac{y_2-y_1}{x_2-x_1}. With the given points, we can directly plug them in and solve.

m=\frac{10-2}{5-1} =\frac{8}{4}=2

Now, we know that the slope is 2.
