Inequality review

When I graph an equation that has a > or < symbol I use a _________________ circle when graphing.

• open

• closed

• half

• shaded

When solving an inequality like the following: 4a + 3 < 31 since the co-efficient of the variable is __________________________ you solve the equation just as you would with any other equation.

• an integer

• not zero

• positive

• negative

When I graph an equation that has a ≤ or ≥ symbol I use a _________________ circle when graphing.

• half

• open

• closed

• none of these is correct

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

Match the graph with its inequality.

• 11 < a

• 11 > a

• 11 ≤ a

• 11 ≥ a

(Choose all of the correct choices)

If I have a negative coefficient then I must ___________________ the symbol at the end of my answer/solution.

• reverse

• change

• overlook

• flip

Which graph matches the inequality
r ≥ -6?

• A
• B
• C
• D

Solving an equation like this: 37 ≤ 6n-11 is the ____ as you would with any other equation.

When solving an equation like this: 2x - 6 + 8x ≥ 9x - 2 ​ ​ (a)   like terms together on the left side of the equation.

Then I would ​ (b)   9x from both sides of the equation. Next, I would ​​ (c)   6 to both sides of the equation. Finally x would equal ​ (d)

• subtract
• multiply
• divide
• 4
