Hey, I don´t understand the graphing part of inequalities.

Mathematics
1 answer:
stiks02 [169]3 years ago
7 0

Answer:

See explaination

Step-by-step explanation:

While graphing inequalities, think of the inequality sign as an equal sign.

So, y=mx+b.

Say the inequality was y>3x+7, I would think fo the > as an equal sign.

So, in your head, "write" it like this: y=3x+7. Hope this helps.

Virty [35]
The answer is - 40. Observe.

y/-4 + 5 = 15
y = -40 
-40/-4 = 10
10 + 5 = 15 

Thus, y= -40

I need to show work...
laiz [17]

Answer:

118

Step-by-step explanation:

AD = BD

5x - 11 = 3x + 17

Move the constants to the one side

5x - 11 = 3x + 17

    + 11         + 11

5x = 3x + 28

Move the constants to the other side

5x = 3x + 28

- 3x -3x

2x = 28

Divide both sides by 2

2x/2 = 28/2

x = 14

Let's move back to the original equations

Substitute x with 14

5(14) - 11

3(14) + 17

Use Order of Operations

5(14) - 11 = 59

3(14) + 17 = 59

Add up both answers

59 + 59 = 118
