First we calculate the ambio rate from x = 0 to x = 15:
We have:
R = ((80-10) / (0-15))
R = -4.666666667
We now calculate for the entire interval:
from x = 0 to x = 20:
R = ((80-2) / (0-20))
R = -3.9
Answer:
What is the average rate of change over the entire slide?
R = -3.9
The average rate of change from x = 0 to x = 15 is about -4.667. How does the average rate change from x = 0 to x = 20 compare to this number?
The percentage difference is:
(-3.9 / -4.666666667) * (100) = 83.57142857%
100-83.57142857 = 16.42857143%
The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.
Step-by-step explanation:
Let,
Cost of one large pizza = x
Cost of one breadstick = y
According to given statement;
4x+y=34.46 Eqn 1
2x+y=18.48 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 2
Putting x=7.99 in Eqn 2
The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.

Answer:
(20x30)= 600
that's the area of rectangular plot
3ft wide sidewalk means both +3 on left and +3 on right, also both +3 up and +3 down
which means u have to do 26x36=936
then subtract
936-600=336 square feet
Step-by-step explanation:
Complete question;
A booster club paid for pizzas for an end of season party. They paid $13 for each pepperoni pizza and $11 for each plain pizza. The club bought a
total of 18 pizzas for the party and paid a total of $212.
Drag and drop the numbers to the boxes to create an equation which models this situation if x = the number of pepperoni pizzas and y = the number of plain pizzas bought.
Answer:
13x + 11y = 212
Step-by-step explanation:
They bought 2 different recipe of pizza. The first is the pepperoni pizza and the second kind is the plain pizza. The pepperoni pizza cost $13 each while the plain Pizza cost $11 each. The total number of pizza bought is 18 in number.
The total cost of the pizza is also $212.
number of pizza bought = 18
total cost of pizza = $212
x = the number of pepperoni pizzas
y = the number of plain pizzas
The number of pepperoni pizzas multiply by the cost for each will give the cost of the pepperoni pizzas. This same method is applied to get the cost of the plain pizzas.
Therefore, adding the individual cost of the kinds of pizza will give the total cost of the pizzas.
13x + 11y = 212
