Question

Solve the combined inequality 3x - 7 > -10 and 5x + 2 < 22, then graph the solution.




First one:
3x-7>-10
3x>-10+7
3x>3
x>1
Second one:
5x+2<22
5x<22-2
5x<20
x<4

Answer 1

Watch out for the sign on line 3 of the first one.

Answer 2

3x > 3 is not correct. Check again.

Answer 3

Whats -10+7

Answer 4

-3

Answer 5

x<-1

Answer 6

Yes .. whatch out for that simple mistake

Answer 7

O.O i use to do it all the time

Answer 8

3x > -3
x > -1 ( not less than -1)

Answer 9

Oh okay thank you so much, is the second one good?

Answer 10

The second one is good.

Answer 11

Yes^ remember that the sign only switches if u devide or multyply by a negative like
exmple:
-2x<8
x>-2

Answer 12

or -x/2>4=x<-8

Answer 13

okay, which way would the sign go? I know they are both open circles

Answer 14

The solution is: -1 < x < 4

There should be a open circle at -1 and at +4
And the solution will be the line joining those two points on the x axis.
