Question

Please help I keep getting this wrong

Answer 1

X/4 < = -3/2...multiply both sides by 4
x < = -3/2 * 4
x < = -12/2
x < = -6.......graph : 1 (because less then shades to the left....and an equal sign in the problem means the dot is solid)

7x/9 > - 14/3 ....multiply both sides by 9
7x > - 14/3 * 9
7x > -42...divide both sides by 7
x > -42/7
x > - 6......graph : 4 (because greater then shades to the right...and no equal sign means it is an open dot)

-75x/4 > 225/2...multiply both sides by 4
-75x > 225/2 * 4
-75x > 450...divide both sides by -75, and change the sign
x < -450/75
x < - 6.......graph : 2 (because less then is shaded to the left...and no equal sign means an open dot)

2x/3 > -16/3...multiply both sides by 3
2x > -16/3 * 3
2x > -16 ...divide both sides by 2
x > -16/2
x > -8......graph : 3 (because greater then shades to the right....and no equal sign means an open dot)
