Solve Inequality with Negative Coefficient

Solve for t.

6t + 4 ≤ -2

• t ≤ -1 

• t ≤ 1

• t=1

• 1=t

Solve: -2x ≤ 14

• x ≤ 7

• x ≤ -7

• x ≥ 7

• x ≥ -7

-9a - 1 < 26

• a<-3

• a<3

• a>-3

• a>3

• No, because the coefficient of n is negative

• No, because the coefficient of n is positive

• Yes, because the coefficient of n is negative

• Yes, because the coefficient of n is positive

• No, because the coefficient of n is negative

• No, because the coefficient of n is positive

• Yes, because the coefficient of n is negative

• Yes, because the coefficient of n is positive

• x < -2

• x > 2

When do we switch the inequality symbol?

• when multiplying or dividing by a NEGATIVE

• when adding and subtracting a NEGATIVE

• we never switch the inequality

• When there is a negative in the problem

-2x + 6 < 30

• x > 9

• x < 12

• x > -12

• x < -9

When the co-efficient of the variable is ___________________________you solve the equation just as you would with any other equation, but at the end you must reverse the sign at the end.

• positive

• negative

• a fraction

• neutral

When an inequality like this one: -6q – 7 ≤ 53, is solved and graphed, because of the line under the less than sign we would ____________!

• go back to the origin

• close the circle and the graph

• open the circle then graph

• none of these is correct
