Question

Graphing, look at picture for question

Answer 1

7>-2x+3>=-7 do you know how to solve this?

Answer 2

I got -2, 5 when i solved it

Answer 3

we want to get x alone in the middle so first we want to get rid of the 3 so -3 from all three parts of the inequality
7-3>-2x+3-3>=-7-3
4>-2x>=-10
now we want to get rid of the 2 from the middle so we will devide each part by two, but when we multiply or devide by a negative we must flip the signs of the inequality so
4/-2<-2/-2(x)<=-10/-2
-2<x<=5
so the set is
(-2,5]
which option is that?

Answer 4

o sorry I did not read that, but what is important here is that 5 is included, but -2 is not. Understand?

Answer 5

Yes.. so how would i know what graph it is?

Answer 6

Answer 7

we are saying that if we put in an x to that inequality statement, as long as that x is in the interval (-2,5] it is true, in other words all x values between -2(including -2) and 5(not including 5) the way we denote including on a graph is with a solid dot, and the way we denote not included is an open dot, so whats the answer?

Answer 8

It is the 1st graph?

Answer 9

Or the 3rd one? I'm not sure..

Answer 10

we said the lowest it can go is -2, so it for sure cant be anything that includes -4 and -5

Answer 11

So it has to be the 3rd graph right? Because that doesn't include -4

Answer 12

we are saying that if we put in an x to that inequality statement, as long as that x is in the interval (-2,5] it is true, in other words all x values between -2(*not including -2) and 5(*including 5) the way we denote including on a graph is with a solid dot, and the way we denote not included is an open dot, so whats the answer?

Answer 13

sorry i wrote that wrong the first time, i made changes at *

Answer 14

we want x values between -2 and 5, which graph on there has x values between -2 and 5? Dont even think about the open closed dot

Answer 15

yes:)

Answer 16

why you delete? you were right:)
