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

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.

Did any get the answer for puzzle 3 in Pythagorean Theorem Digital Escape!

Answers

The formula relations given by Pythagorean theorem is used to

determine the lengths and area of the given squares and triangles.

Responses:

1. Area of a is H: 25

2. Length of b is I: 5

3. Length of C is A: 7.94

4. Area of d is B: 35.73

Where can the Pythagorean theorem be used to find the lengths and areas of a figure?

1. Given;

The area of the side squares are; 9 m² and 16 m²

According to Pythagorean theorem, we have;

Area of square a = 9 m² + 16 m² = 25 m²

Area of a is H: 25

2. = Area of side square a

Therefore;

b = √(25 m²) = 5 m

Length of b is I: 5

3. Given;

Area of the squares adjacent to the hypotenuse side and a leg are;

144 m² and 81 m² respectively

According to Pythagorean theorem, we have;

C² = 144 m² - 81 m² = 63 m²

C = √(63 m²) = √(9 × 7 m²) =  3·√7 m ≈ 7.94 m

Length of C is A: 7.94

4. Area of triangle d = [tex]\frac{1}{2}[/tex] × √(81 m²) × 7.94 m ≈ 35.73 m

Area of d is B: 35.73

a whole number by a unit fraction is the same as multiplying a whole number by the of the unit fraction.

Answers

Answer:

A whole number divided by a unit fraction is the same as multiplying a whole number by the inverse of the unit fraction.

Step-by-step explanation:

Given

[tex]8 \div \frac{1}{5} = 40[/tex]

[tex]8 * 5 = 40[/tex]

Required

Explain why both expressions are correct

No dropdown to select from. So, I will provide a general solution.

When a number is divided by a fraction.

Take for instance:

[tex]8 \div \frac{1}{5}[/tex]

The above can be expressed as the product of the number and the inverse of the fraction.

The inverse of 1/5 is 5.

So, we have:

[tex]8 \div \frac{1}{5} = 8 * 5[/tex]

The result of the above expression is:

[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]
