Solve Inequalities Add Subtract

Write an inequality for Graph 2.

Write an inequality for Graph 3.

−6 < 2t − 5 < 3

• {t |−0.5 < t < 4 }

• {t | 0.5 < t < −4}

• {t | −0.5< t < 2}

• { t | 1.5 < t < −2}

3x + 2 < -7 or -4x + 5 < 1

• All real numbers

• x < -3 and x > 1

• x < -3 or x < 1

• x < -3 or x > 1

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

• <, >

• ≤, ≥

Why do I draw a closed circle when it's less than or equal to or greater than or equal to?

• Because we are INCLUDING that solution

• Because we are NOT INCLUDING that solution

0 < x + 7 < 9

• -7

• -7

• -7>x and x>2

• -7>x or x>2

-8 < 2(x+4) or -3x+4 > x-4

• { x | x < -8 or x < 2 }

• { x | x > -8 or x < 2 }

• { x | -8<x<2}

When do you "flip the inequalities sign"?

• When you add or subtract a negative

• When it's a 1-step problem

• When you multiply or divide a negative

• When it's a 2-step problem
