Question

Double check my answers? (2 questions)

1.
3y + 2 ≥ 5y + 8
3y + 2 - 5y ≥ 5y + 8 - 5y
-2y + 2 ≥ 8
-2y + 2 - 2 ≥ 8 - 2
-2y ≥ 6
-2y/-2 ≥ 6/-2
y ≥ 4?

2.
7y - 3 ≤ 10y + 9
7y - 3 - 10y ≤ 10y + 9 - 10y
-3y - 3 ≤ 9
-3y - 3 + 3 ≤ 9 + 3
-3y ≤ 12
-3y/-3 ≤ 12/-3
y ≤ 4?

I'm not sure I did these right?

Answer 1

@AloneS @wwhitlock @welshfella

Answer 2

#1 seems wrong

Answer 3

Waitt I'm confused both of them are wrong?

Answer 4

I don't think either of them are right but I don't know where I messed up or how to fix it.

Answer 5

Oh lol

Answer 6

Well than let's go over it

Answer 7

Mkay

Answer 8

I think in problem 1 your division is wrong. 6 / -2

Answer 9

OH wait it should be -3 because a negative + negative = positive, right?

Answer 10

For #1

Answer 11

So this is how i'll do, and you check
\(\ 3y+2−5y≥5y+8−5y\)
\(\ −2y+2≥8\)
subtract 2 from both sides \(\ −2y+2−2≥8−2\)
\(\ −2y≥6\)
and then divide both sides by -2.
\[\frac{ -2y }{ -2 }=\frac{ 6 }{ -2 }\]
y≤−3 is what i got for ma answer

Answer 12

That's what I got too

Answer 13

Yeah, that's it.

Answer 14

That means for the other problem it should be -4...

Answer 15

Yes for #2 it should be y≥−4

Answer 16

Yep

Answer 17

Thank you both!
