PLZZ HELP I NEED MY GRADE TO GO UP BC ITS ALMOST MY BIRTDAY AND I CANNOT FAIL!! P WILL MARK Brainliest Last Sunday Lily and Maddie went to Sarah’s Sweet Shop and purchased one cupcake and one brownie. Their bill was $4.50.

The next day they brought their friend Jessica and purchased 3 cupcakes and one brownie. This time their bill was $9.50.

Let x represent the price of each cupcake.

Let y represent the price of each brownie.

2.The first equation in the system is: x+y=4.50

3.The second equation in the system is : 3x + y = 9.50

4.Solve the system from question 3 to find the price per cupcake.

5.Find the price per brownie.

6.Find the total cost to purchase 4 cupcakes and 4 brownies from the shop.

step-by-step explanation:

yuo ned the activity or vertical angle of the form of 1,7 but 2,2 has a c4,2 as it verticie so i not have a car

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

it would be a on edgenuit y

the diagram below is your final answer
