Solve: -4x < .8
Solution: Using the Multiplication Principle, multiply both
sides of the inequality by -.25. Then reverse the
signs.
-.25(-4x) > -.25(.8)
x > -.2
solve using the multiplication principle:
-7x > 1/15

Wow you lost me. So how would that work with a fraction, do you still do it by -.25?
If 3X - 1 = 11, what is the value of X^2 + X?
-7x > 1/15
divide both sides by -7, remembering to reverse the inequality sign
x < -1/105
divide both sides by -7, remembering to reverse the inequality sign
x < -1/105
