Question

Solve each inequality. Graph and check the solution.

Answer 1

1. -4x > -16...divide by -4 and change inequality sign
     x < -16/-4
     x < 4

2. -y/2 < 6 ...multiply both sides by 2
     -y < 12 ...multiply both sides by -1 and change inequality sign
      y > -12

3. -5a < -20....divide both sides by -5 and change inequality sign
     a > -20/-5
     a > 4

4. -b/2 > -1....multiply both sides by 2
     -b > -2...multiply both sides by -1 and change inequality sign
     b < 2

5. -4b < 24....divide both sides by -4 and change inequality sign
     b > -24/4
    b > - 6

6. -7c < -14....divide both sides by -7 and change inequality sign
     c > -14/-7
     c > 2

7. -d/3 > -9...multiply both sides by 3
    -d > -27...multiply both sides by -1 and change inequality sign
     d < 27
