Answer 1

Answer:

x y

3 3

5 7

1/2 -2

-1 -5

Step-by-step explanation:

You have to plug the numbers in to find out the chart

2(3)-3=y

6-3=y

3=y

2x-3=(7)

add the 3 on both sides to make the x by its self

2x=10

divide both sides by 2

x=5

2(1/2)-3=y

1-3=y

y=-2

2x-3=(-5)

add the 3 to both sides

2x=-2

divide the 2 on both sides

x=-1

Answer 2
Substitute x=3 in the given equation
We get 2(3)-3=y
6-3=y
So, y=3
next, substitute y=7 in the equation
We get 2x-3=7
2x=7+3
2x= 10
X= 5
Keep substituting the values..
When x= 1/2, Y = -2
When y= -5, x= -1
With these coordinates, plot the points on the graph

These two triangles are scaled copies of one another. The area of the smaller triangle is 9 square units. What is the area of the larger triangle? Explain or show how you know please.

Answers

Answer:

The area of the larger is 36  units^2

Step-by-step explanation:

The scale factor is 6/3 = 2

When we work with areas, it is scale factor squared

scale factor ^2 = area of larger / area of smaller

2^2 = area of larger / 9

4 =area of larger / 9

Multiply each side by 9

4*9 = 36

The area of the larger is 36  units^2

The area of 36 units is larger

Answer:

14/15

Step-by-step explanation:

Find common denominators. Note that what you do to the denominator, you do to the numerator.

Use 15 as the common denominator:

(-2/5)(3/3) = (-6/15)

(4/3)(5/5) = (20/15)

Combine like terms:

-6/15 + 20/15 = (20 - 6)/15 = 14/15

14/15 is your answer.

It takes Kevin 15 minutes to drive 5 1/2 miles.
How many miles does Kevin drive per minute?
a) 11/30
b) 5/6
c)2 8/11
d) 3

Answers

Answer:  11/30 miles per minute

Step-by-step explanation:

To get miles per minute

Divide the distance by the time

5 1/2 ÷ 15 . Change 5 1/2  to an improper fraction 11/2

invert the divisor and multiply: (Multiply by the reciprocal of 15: 1/15)

11/2 × 1/15 = 11/30

Here, we are required to determine how many miles does Kevin drive per minute.

The number of miles Kevin drives per minute is 0.3667miles.

According to the question, Kevin drives 5 1/2 miles (5.5 miles) in 15 minutes.

To determine how many miles Kevin drives per minute, we need to determine Kevin's speed over the 15 minutes in which he covered 5.5 miles.

Speed = distance/time

Speed = 5.5miles/15minutes

Therefore, Speed = 0.3667 miles per minute.

Ultimately, Kevin drives 0.3667miles per minute.

How many solutions exist for the equation: 8(4-2x)=4(3-5x)+4x

A) Two solutions
B) One solution
C) No solution
D) Many solutions

Answers

Answer:

C

Step-by-step explanation:

We have the equation:

[tex]8(4-2x)=4(3-5x)+4x[/tex]

Let's expand both sides. Distribute on the left:

[tex]32-16x=4(3-5x)+4x[/tex]

Distribute on the right:

[tex]32-16x=12-20x+4x[/tex]

Combine like terms on the right:

[tex]32-16x=12-16x[/tex]

Add 16x to both sides:

[tex]32\neq12[/tex]

This is not true.

So, our equation has no solutions.

This would mean that our two linear equations are parallel to each other.

The original quantity is 20 and the new quantity is 15. Adam incorrectly says the percent decrease is about ​14.29%. What is the correct percent​ decrease? What error did Adam likely make when finding the percent​ decrease? The correct percent decrease is 25 25​%. What error did Adam likely​ make? A. divided the difference of the two quantities by the sum of the two quantities. B. divided the difference of the two quantities by the product of the two quantities. C. divided the difference of the two quantities by the new quantity. D. divided the new quantity by the original quantity.

Answers

Answer: A. divided the difference of the two quantities by the sum of the two quantities.

===================================================

Explanation:

The difference of the quantities is 20-15 = 5

The sum of the quantities is 20+15 = 35

Dividing those results leads to 5/35 = 0.142857 which rounds to 0.1429

That converts to 14.29%

This is likely the path Adam took. This path is incorrect. The correct steps are shown below

---------------------

Difference = 20-15 = 5

Divide the difference over the original quantity

5/20 = 1/4 = 0.25 = 25%

We have a 25% decrease because the new quantity (15) is smaller than the old quantity (20)

----------------------

Here's another way to approach the problem

A = old value = 20

B = new value = 15

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (15-20)/20 ] * 100%

C = (-5/20)*100%

C = -0.25*100%

C = -25%

The negative C value means we have a negative percent change, ie we have a percent decrease. So this is another way to get a 25% decrease.

Answer:

M+4.63=T

Step-by-step explanation:

M represents the amount that he spent on his groceries. T is total

The addition equation to represent Jackson's net change in money is x + (-y) = 4.63.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that:

Jackson receives 4.63 as his change at the grocery store. He places it into a charity donation jar at the register.

Let x be the initial amount before purchase

Let y be the cost of the item purchased

Initial amount + cost of the item purchased = change received

The addition equation to represent Jackson's net change in money is:

x + (-y) = 4.63

Here y is with the negative sign because it is incurred

The change received = 4.63

Thus, the addition equation to represent Jackson's net change in money is x + (-y) = 4.63.
