Answer:

X= -44

Step-by-step explanation:

Multiply parenthesis by 2. Distribute 2 through the parenthesis. Collect like terms. Calculate the difference. Move variable to the left side and change it's sign. Move constant to the right side and change it's sign. Collect like terms. Add the numbers. Change the signs on both sides of the equation. Then you'll get X= -44

Answer:

44/7

Step-by-step explanation:

First, carry out the indicated multiplication, using the Distributive Property of Multiplication:

-4x + 2(3x – 1) - 12 = 3x + 30 becomes:

-4x + 6x – 2 - 12 = 3x + 30

Next, combine all the x terms and all the constants.  We get:

10x - 14  = 3x + 30, or 7x = 44

Dividing both sides by 7 yields x = 44/7.

Does the chart below represent a proportional relationship? What is the rate of change?
Lilit [14]

This chart represents a proportional relationship. The rate of change will be 4.

<h3>What is the constant of proportionality?</h3>

Firstly, there is a proportional relationship.

Two values x  and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.

The constant k is called the constant of proportionality.

Given;

x y

1 4

2 8

3 12

4 16

Here, x = ky

put the first value

k = 1/4

This chart represents a proportional relationship.

So the rate of change will be

Rate = \dfrac{y_2 - y_1}{x_2 - x_1}\\\\Rate = \dfrac{8 - 4}{2 - 1}\\\\Rate = 4

In a cafeteria, 1/6 of the students are eating salads, and 2/3 are eating sandwiches. There are 18 students in the cafeteria. Ho
inna [77]

Answer:

3 students are eating lunches other than salads and sandwiches.

Step-by-step explanation:

To solve this you know that there are 18 students in the cafeteria and 1/6 of them are eating salads and 2/3 are eating sandwiches right? So you would have to think about what 1/6 of 18 is so you know how many students are eating salads, and 1/6 of 18 is 3 so there are 3 students eating salads. Now, you have to find out how many students are eating sandwiches, so you need to know what 2/3 of 18 is. 2/3 of 18 is 12 so now you also know that there are 12 students eating sandwiches. Next, you have to add 12 and 3 and you get 15. Since you know that there are 18 students in the cafeteria, you have to subtract 18 by 15, and you should get 3. So 3 students are eating lunches other than salads or sandwiches.

Hope this helps you! :D

Consider the linear equation y = 2x - 4. Write an equation in slope-
HACTEHA [7]
Answer: y=2x+14

Explanation:
Y=mx+b
Y= 2x-4
M=2

Y= 2x+b

2 = (2 x -6) + b
2=-12+b
12+2=12+b
-12
14=0+b
14=b

Y=2x+14
