Will the symbol flip?

-4x + 14 ≤ 54

• yes

• no

What would you do to BOTH sides to solve the inequality?

x + 5 ≤ 13

Type in the word "add, subtract, multiply, divide" and then the number. EXAMPLE, multiply 8

10 ≥ x - 3

• x ≤ 13
• x ≥ 13
• x ≤ 7
• x ≥ 7

Which explains how to solve,

 $-3x\ +\ 4\ >\ 28$  

• Flip the symbol
  -4 both sides, then divide -3 both sides
  

• Flip the symbol
  -4 both sides, then divide 3 both sides
  

• Flip the symbol
  +4 both sides, then multiply -3 both sides

• Flip the symbol
  +4 both sides, then multiply -3 both sides

Which explains what the number line will look like?

 $-3x\ +\ 4\ >\ 28$  

• Open circle going left

• Open circle going right

• Closed circle going left

• Closed circle going right

Which explains how to solve,

 $\frac{x}{8}-2\le\ -1$  

• No Flip
  +2 both sides, then divide 8 both sides

• No Flip
  -2 both sides, then divide 8 both sides
  

• No Flip
  +2 both sides, then multiply 8 both sides

• No Flip
  -2 both sides, then multiply 8 both sides
