2x + x + 4 = 3x + 4

Answers

Answer:

Infinitely many solutions

Step-by-step explanation:

2x + x + 4 = 3x + 43x + 4 = 3x + 4

Both sides of the equation are exactly same.

It means regardless the value of x the equation is true.

The equation has infinitely many solutions.

2x+x+4=3x+43x+4=3x+4

As both sides are equal

There present infinite number of solutions

Triangle MNO is transformed to produce triangle PQR. What transformations guarantee triangles MNO and PQR are congruent

Answers

Answer:

C, D, and E are corrects.

Step-by-step explanation:

Two plane figures are congruent if and only if one can be obtained from the other by a sequence of rigid motions. The rigid transformations are reflection, rotation, and translation. The image from these transformations will not change its size or shape.

A dilation is a nonrigid transformation that can produce enlarged or reduced images from a given pre-image.

Therefore only C, D, and E are corrects.

A. a dilation, then a translation

B. a reflection, then a dilation

C. a reflection, then a rotation

D. a rotation, then a translation

E. a translation, then a reflection

The transformations guarantee triangles MNO and PQR are congruent should be considered is option C, D, and E.

What is congruent?

The two plane figures should be considered as the congruent when one should be obtained from the other via the sequence of the fixed motions. Here the right transformation could be in the form of reflection, rotation, and translation.

Also, the image arise form transformations should remain the same with respect to the size or shape.

Therefore only C, D, and E are corrects.

This is an incomplete question. Please find the options below.

A. a dilation, then a translation

B. a reflection, then a dilation

C. a reflection, then a rotation

The sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees

What is a regression model?

A regression model is used to determine the association and correlation between two variables

Using a graphing calculator, the sine regression model of the dataset is:

[tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex]

To calculate y(30), we substitute 30 for x in the equation.

So, we have:

[tex]y =20.077 \sin(0.500 * 30- 1.959) + 67.577[/tex]

Evaluate the product

[tex]y =20.077 \sin(15- 1.959) + 67.577[/tex]

Evaluate the difference

[tex]y =20.077 \sin(13.041) + 67.577[/tex]

Evaluate the sine value

[tex]y =20.077 *0.4570+ 67.577[/tex]

Evaluate the product

[tex]y =9.1752+ 67.577[/tex]

Evaluate the sum

[tex]y =76.7522[/tex]

Approximate

[tex]y \approx 76.8[/tex]

Hence, the sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees

2) Collect like terms.

Nadia has £5 to buy pencils and rulers. Pencils are 8p each. Rulers are 30p each. She says “I will buy 15 pencils. Then I will buy as many rulers as possible. With my change, I will buy more pencils.” How many pencils and how many rulers does she buy?

Answers

Answer:

Total pencils: 17

Total rulers: 15

Step-by-step explanation:

"I will buy 15 pencils."

15 * 8p = £1.20

15 pencils

"Then I will buy as many rulers as possible."

£5 - £1.20 = £3.80

£3.80/30p = 12 remainder 20p

12 rulers

"With my change, I will buy more pencils.”

20p/8p = 2 remainder 4 p

2 pencils

Total pencils: 17

Total rulers: 15

The total weight W of the barricade in kilograms is a function of x, the number of boxes Rei stacks on the table.
Write the function's formula.
W, equals

Answers

Answer: The answer is W=70+30x

Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.

The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.

Therefore, the weight of the table without boxes is 70 kilograms.

Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -

So, if 'g' denotes the weight of the table alone, then we have,

Step-by-step explanation:

its either C or D and yup sure

Answer:

3,375 mm³

Step-by-step explanation:

To find the volume of a cube or rectangular prism, multiply the length, width, and height of the figure. In this case, the figure is a cube, so all the side lengths are equal. So, all you have to do is multiply 15 three times.

15 · 15 · 15 = 3,375

The answer is D, 3,375 mm³. Use the cubed symbol to show volume :) Good luck

The dot plot shows the favorite sport to play according to some middle school students chosen at random. Which statement is true according to the information in the dot plot ?

Answers

What are the options?

Answer:

B: More than 25% of the students chose football and tennis as their favorite sport to play.

Step-by-step explanation: You need to find the total, which is 50. Since it says more than 25 percent of the students chose football and tennis your answer will need to be more then 25 percent. You add football plus tennis (10+3=13). Now you set up your proportion- 50 as your whole/total, 13 as your part, and substitute you percent with a variable like (p), then 100. Cross multiply. I did a shortcut which replaces the Ice Ice Baby process, so multiply 13x100= 1300, then your product divide it by 50 ( total) 1300/50= 26. This makes the statement true.

Answers

Answer:

w > -1

Step-by-step explanation:

Hello There!

We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations

So we want to get rid of the 8 in 8w

8w is the same as 8 times w (multiplication)

The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8

-8/8 = - 1

8w/8=w

we're left with w > -1
