5m + 8 and -2m - 6. Could i get the answer and an explanation?

Answers

Answer:

m=-5

Step-by-step explanation:

Simplifying

5m + -6 = 8m + 9

Reorder the terms:

-6 + 5m = 8m + 9

Reorder the terms:

-6 + 5m = 9 + 8m

Solving

-6 + 5m = 9 + 8m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-8m' to each side of the equation.

-6 + 5m + -8m = 9 + 8m + -8m

Combine like terms: 5m + -8m = -3m

-6 + -3m = 9 + 8m + -8m

Combine like terms: 8m + -8m = 0

-6 + -3m = 9 + 0

-6 + -3m = 9

Add '6' to each side of the equation.

-6 + 6 + -3m = 9 + 6

Combine like terms: -6 + 6 = 0

0 + -3m = 9 + 6

-3m = 9 + 6

Combine like terms: 9 + 6 = 15

-3m = 15

Divide each side by '-3'.

m = -5

Simplifying

m = -5

5m+8=-2m-6
Add 2 to 5
7m+8=-6
Subtract 8 from -6
7m=-14
Divide 14 by 7
M=2

Simplify.

−6x+8/6−3/2x−1/2+5/2x

Enter your answer in the box.

Do not use decimals in your answer

Answers

Answer: =−5x+5/6

Step-by-step explanation:

Your equation:

−6x+8/6-3/2x-1/2+5/2x

Gather all the numbers with the x variable:

-6x - (3/2x) = -7 1/2x

-7 1/2x + (5/2x) = -5x

-5x is the answer to your first part.

Finally, gather all the numbers without the x variable.

(8/6) - (1/2) = 5/6

This makes your answer into -5x+5/6 ! Hope this helps :D

The equation will be -5x+5/6

Which shows one way the equation can be represented in words?

6) Write a system of linear inequalities that is given by the following graph.

Answers

Answer:

The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be

⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)

*******x******
please show work if can

Answers

Answer: 44

Step-by-step explanation:

Let your age be x.

Then your mother's age will be 2x + 12.

After 8 years,

Your age will be x + 8.

Your mother's age will be 3(x + 8) - 20 = 3x + 24 - 20 = 3x + 4.

This is equal to 2x + 12 + 8 = 2x + 20

2x + 20 = 3x + 4

3x - 2x = 20 - 4

= x = 16

I think it will be 16
