4.4: I can solve inequalities

Just like equations.. with ONE main difference:

Flip the sign if you have to multiply or divide both sides by a NEGATIVE number.

Solving inequalities:

Isolate the variable by:
Simplifying both sides of the inequality
Remove constants by undoing addition/subtraction
Remove coefficients by undoing multiplication/ division <- WATCH OUT ON THIS STEP
If you are multiplying or dividing by a negative number, FLIP the inequality sign!

Multiple Choice

Lisa went to the mall to do her back-to-school shopping. When she returned home, she noticed that the number of shirts(s) she purchased was 3 more than twice the number of pants(p) she bought. Write an equation that can be used to represent the number of shirts Lisa purchased

p = 3 + 2s

s + 2p = 3

2p = s + 3

s = 3 + 2p

Multiple Choice

Roberto deposits the same amount

of money each month into a checking

account. Use the table to write an

equation to model his balance, B,

after m months.

B = 200 + 55m

B = 200 - 55m

B = 200m + 55

B = 200m - 55

Multiple Choice

A cell phone company charges $3.00 to make a phone call plus $0.15 for each minute for each minute you talk. Which equation would you use to determine the total cost, c, of a phone call that is m number of minutes long?

c = 3.00 - 0.15m

c = 0.15 + 3.00m

3.00 = c + 0.15

c = 3.00 + 0.15m
