Solve Equations & Inequalities

What inequality does the number line graph represent?

• 2x +1 < -3

• x + 2 < 4

• -x + 3 > 1

• x + 4 >= 2

Does the given value make the inequality true?  x + 9 > 21, when x = 15

• True

• Not True

Solve for t.

6t + 4 ≤ -2

• t ≤ -1 

• t ≤ 1

• t=1

• 1=t

3x - 2 ≥ 34

• x ≥ -12

• x ≤ -12

• x ≤ 12

• x ≥ 12

4x + 2(x - 6) = 12

• x = 6

• x = 4

• x = 2

• x = -2

-3 − 6(4x + 6) > -111

• x > 3

• x < 3

• x < -3

• x > -3

Find the error in the problem below

19 - 2k = 3k - 1

+3k +3k

19 + 1k = -1

-19 -19

k = -20

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k

3x - 8 < 3(x - 4) + 1

• x < -11

• no solution

• all real numbers

• x > -8

When graphing an inequality, you use an open dot when you use which symbol?
