2 answers:

Answer:
C. x = 5

Explanation:
Step 1 - Simplify the equation by adding the common terms

3x - 7 + 4x = 28
3x + 4x - 7 = 28
7x - 7 = 28

Step 2 - Add seven to both sides of the equation

7x - 7 = 28
7x - 7 + 7 = 28 + 7
7x = 35

Step 3 - Divide both sides of the equation by seven

7x = 35
7x/ 7 = 35/ 7
x = 5

Therefore, the correct answer should be ‘c. x = 5.’

Answer:

x = 5

Step-by-step explanation:

3x - 7 + 4x = 28

Combine like terms

7x -7 = 28

Add 7 to each side

7x - 7 +7 = 28+7

7x = 35

Divide each side by 7

7x/7 = 35/7

x = 5

Y>1 and y>x on a graph

zlopas [31]

So,

$y>1\wedge y>x$

1. Graph each inequality separately.

2. Choose a test point to determine which side of the line needs to be shaded.

3. The solution to the system will be the area where the shadings from each inequality overlap one another (purple area)

As for the system of inequalities we say it's unbounded.

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite

Liono4ka [1.6K]

Answer:

b = -a

Step-by-step explanation:

Since a and b are equally distant to zero but in opposite directions, a and b are opposites, or additive inverses.

The sum of additive inverses is zero.

a + b = 0

b = -a
