Question

Solve the inequality and complete a line graph representing the solution. In a minimum of two sentences, describe the solution and the line graph.

8 ≥ 3x + 5

Answer 1

so we have 8 ≥ 3x + 5
and we want to isolate x, what is the first thing you would want to do?

Answer 2

bring it to both sides???

Answer 3

not quite, you want to first simplify the whole numbers, (8 and 5), to do this, without changing the equation, you can subtract 5 from both the left and right sides, so-
8 - 5 ≥ 3x + 5 - 5
so this simplifies to
3 ≥ 3x

Answer 4

What do you think would be the next step to isolate x?

Answer 5

okay um...I really want to say divide it from the 3 but I'm most likely wrong.

Answer 6

no, thats actually correct! You want to divide both sides by 3.
so you get 3/3 ≥ 3x/3
which simplifies down to
1 ≥ x

Answer 7

Oh, well then. So if it's that simple what's with the two sentence thing?

Answer 8

I think you're meant to draw the number line graph representing your answer and just a line or two explaining what the answer means exactly

Answer 9

so try drawing up a line graph and describing your solution in a line or two

Answer 10

Okay seems a bit pointless to do all that but alright. Thank you for your help.

Answer 11

no problem :)
