Inequalities are expression not separated by an equal sign. None of the inequality is correct since there is absence of equal sign.

<h3>Graph of inequalities</h3>

Inequalities are expression not separated by an equal sign. According to the question, we ned the inequality's graph that will have a dashed boundary line.

An inequality that will have solid boundary line must include only the less than or equal to sign < or greater than or equal to > sign.

From the option given, none of the inequality is correct since there is absence of equal sign.

Find the value of x if A, B, and C are collinear points and B is between A and C.
Andrew [12]

Answer:

x = 6

Option A.

Step-by-step explanation:

We know that

If A, B and C are collineal points, they all pass through a common line.

<--------------14-------------->

A-----------B----------------C

<-----x-----><------x+2---->

Based on the problem and the diagram above,

(x) + (x+2) = 14

(2x+2) = 14

(2x) = 12

(x) = 6

Which of these describes the equation –18x + 9y = –416?
Minchanka [31]

Answer:

We conclude the equation is linear because it can be rewritten in the form y = mx + b.

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the line or linear equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

<u>Important Tip:</u>

The graph of a linear equation is always a straight line.

Convert the given equation in the slope-intercept form

18x + 9y = -416

subtract 18x from both sides

18x+9y-18x = - 18x-416

simplify

9y = -18x - 416

divide both sides by 9

y=-2x-\frac{416}{9}

Now, comparing the equation y=-2x-\frac{416}{9} with a slop-intercept form of linear equation

  • The slope m = -2
  • The y-intercept b = -416/9

Therefore, we conclude the equation is linear because it can be rewritten in the form y = mx + b.

From the attached graph, is also clear that the graph of the equation y=-2x-\frac{416}{9} is a straight line.

Hence, option D is correct.

Lydia wants to buy new boots that cost $130. She has saved 82% of what she needs to buy the boots. How much money has she saved
Lorico [155]

Answer:

Answer:

44 = 12 + M

Step-by-step explanation:

Start with your final amount that everything else is going to equal

44 =

Then, add the $12 that is already saved to the other side\

44 = 12

But, that equation is not true yet, so we have to add the amount of money that she still needs to save

44 = 12 + M

That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.
