Question

Solve the inequality and identify the graph of the solution set. 5-2y>9





Show your work and support your graph choice.

Answer 1

Can you isolate the variable like a regular equation?

Answer 2

Can you put y by itself?

Answer 3

@zepdrix ??

Answer 4

So the first step is solving the inequality :) As these guys have mentioned.
Were you able to solve the inequality yet?
Get the y value alone.\[\huge 5-2y>9\]We'll subtract 5 from both sides,\[\huge -2y>4\]From here, inequalities are a little bit fussy, if you multiply or divide a NEGATIVE across the inequality, you FLIP the inequality!

We're going to Divide both sides by -2, giving us,\[\huge y<\frac{4}{-2}\]
\[\huge y<-2\]Take a look at those steps, make sure you understand that part of it first.

Answer 5

thank you(:

Answer 6

@zepdrix , which picture would it be

Answer 7

Since it's a STRICT inequality, (it doesn't include the "or equal to"), it's going to be one of the graphs with an OPEN circle.

y consists of the values that we want to cover.
So we want all the values that are LESS THAN -2.
Which graph would that be? c:

Answer 8

C?

Answer 9

So C has an open circle at -2, so that's a good thing,
The red line represents the values that Y can take.
Are the red values in C LESS THAN -2?
Hmmm I think they're greater than -2 aren't they? :O see how they're counting upwards?

Answer 10

OH, so A
