Question

can someone please help me with this math question? please? I'll fan and give a medal... please show me how to graph
-1/2 + (1/2)y >= x

Answer 1

What do you mean? @agent0smith that is the whole question... I just need to show the steps to graph that equation

Answer 2

First get it into y = mx+b form

Answer 3

y = -1/2x+(1/2)
like this?

Answer 4

No...

Answer 5

Add 1/2 to both sides you did correct. But then you have

(1/2)y = x+(1/2)

Answer 6

oh okay so, the y = mx+b form of this- -1/2 + (1/2)y >= x = (1/2)y = x+(1/2)

Answer 7

Then how do you get rid of the 1/2 that is being multiplied by y?

Answer 8

umm i'm not sure

Answer 9

Multiply everything by 2/1

Answer 10

ok so -
2*1(1/2)y = x+(1/2)*2*1

Answer 11

multiply EVERY term by 2/1

Answer 12

2/1 not 2*1...

Answer 13

2/1(1/2)y = x*2/1+(1/2)*2/1

Answer 14

Good.

Answer 15

then what do I do?

Answer 16

Do math. Simplify.

Answer 17

2/1*(1/2)y = x*2/1+(1/2)*2/1
2/1*(1/2) = 1
2/1+(1/2)*2/1 = 3

Answer 18

y = 3x+1? or would it be 2x?

Answer 19

No idea what you did :/

Answer 20

\[\large \frac{ 2 }{ 1 }*\frac{ 1 }{ 2 }y=x*\frac{ 2 }{1 }+\frac{ 1 }{2 }*\frac{ 2 }{ 1 }\]

Answer 21

Yes, 2/1*1/2 is 1.

How did you get a 3??

Answer 22

I multiplied...

Answer 23

Keep in mind all three terms are separate. You CANNOT add any of them together.

Answer 24

oh okay

Answer 25

so
2/1+1/2*2/1= 2 ?

Answer 26

Why are you adding anything together at all? You should only be simplifying with multiplying... the x and 2/1 are attached by multiplication

Answer 27

2x+1?

Answer 28

Much better

Answer 29

now graph y=2x+1

Answer 30

thank you very much :) I really appreciate your help!!

Answer 31

Welcome :)

Answer 32

Don't forget you're graphing the inequality \[\large y \ge 2x +1\]
