Solve the linear system using substitution. Show your work.
y = -3x + 3
4x +3y = -1

Answers

Answer 1
Sub y in the second equation by y in the first equation:
We get 4x+3(-3x+3)=-1
4x-9x+9=-1
-5x=-10
x=2
Sub in the first equation
y=-3(2)+3
y=-3
Answer 2

Answer:

x=2 and y=-3

Step-by-step explanation:

y=-3x+3, 4x+3y=-1 solve using substitution

y=-3x+3 solve y=-3x+3 for y

4x+3y=-1

4x+3(-3x+3)=-1 simplify both sides of the equation

-5x+9=-1

-5x+9-9=-1+-9 add -9 to both sides

-5x=-10

-5x/5=-10/-5 divide both sides by -5

x=2

substitute 2 for x in y=-3x+3

y=(-3)(2)+3

y=-3 simplify both sides of the equation

answer; x=2 and y=-3

Part C: Greg had a rectangular vegetable garden that was 4 feet wide by 5 feet long. He increased the length of his garden by 2 feet and doubled the width. How many square feet larger is the area of his new garden compared to the area of his old garden? In a short paragraph, explain your answer in your own words.

Answers

part a: c. 96 square feet

part b: 60 inches

part c: 36 square feet


explanation: I multiplied 4 and 5 because area = l•w meaning the garden was originally 20 square feet. I then doubled the making it 8 and added two feet to the length making it 7 feet. Since area equals l•w i multiplied 8 and 7 getting 56 square feet. Since the question asked, “how many square feet larger,” I subtracted the new area, 56 square feet, by the old one, 20 square feet, and got 36 square feet.

Tonya sampled 35 customers leaving the grocery store to find out how long they spend shopping. The results were that two people spent less than 15 minutes shopping, 28 people spent between 15 minutes and an hour shopping, and five people spent over an hour shopping.

Inference: Most customers spend less than an hour shopping.

Defend or challenge the inference with at least two complete sentences.

Answers

Answer:

challenge because it said 28 people spent between 15 and an hour if that is so the could have been there for an hour so there

Step-by-step explanation:

Answer:

The inference makes an incorrect statement.

Step-by-step explanation:

It is said that Tonya sampled 35 customers, where 28 of them spent 15-60 minutes, and 5 people spent over 60 minutes. This means that there are already 5 people that shop for over an hour. There may also be a bigger portion of shoppers that shop for exactly 60 minutes (1 hour), which is NOT less than 1 hour.
