Solve for x.
2x > 8
x > 4
True or False
When solving inequalities, flip the sign when multiplying both sides by a negative. Do not flip the sign when dividing both sides by a negative.
FALSE!!!!!
Flip the sign when multiplying or dividing both sides by a negative.
Solving Inequalities
4 < f + 6 < 5
What is:
-2 < f < -1
When solving absolute value equations and inequalities, you must first ISOLATE the absolute value. In other words, get the absolute value by itself.
Solve:
|x - 4 | < 4
What is
0 < x < 8
x>0 AND x<8
Solve
X + 4 < -88
X < -92
Solving Inequalities
Solve for x.
2x - 5 > - 11
x > -3
Graph the inequality:
True or False?
-4 is included in the solution of
x > -20.
True.
-4 is greater than -20.
- 4 > -20
Solve:
3|c - 2| > 6
c < 0 OR C > 4
True or False:
Two 12-inch pizzas have more pizza than a 17-inch pizza.
False!
Two 12-inch pizzas are one square inch smaller than a 17-inch pizza.
True or False:
Michigan is larger than Great Britain.
True!
The area of Great Britain is about 94,226 square miles, including land and water. The area of Michigan is 96,716 square miles, including land and water.
Graph the inequality:
0<=x<3
True or false:
If the variable is getting pointed to, shade right.
False.
If the variable is getting pointed to, shade left.
Evaluate the following absolute value expression:
| -4 + 6 - 13| - 4 = ?
7
z/30>70
Solve the Inequality
z > 2,100
Is the 3 included in the solution to this inequality?
-9x + 1 > -71
Yes, because x must be less than 8.
Solve
-3p + 1 < -11 OR p + 4 < 6
p > 4 OR p < 2
True or False:
We use a closed circle to represent the inequalities < and >.
False

True or False:
Pottery existed before people with blue eyes existed.
True.
A 2008 study traced the gene for blue eyes to a person who lived 10,000 years ago. Some of the world's oldest pieces of pottery date back to 20,000 years ago.
