### FIRE UP!!

• Pickup from Front Desk:
• Parent Function Packet
• ½ Page sheet

Welcome BACK! 

Warm-up
• Distributive Property
• Simplify the following expression. Discuss with your neighbor.
• -2(3x – 5)
• -6x + 10
Fortune 500 Companies
• We can teach our employees the technical parts of the job, but they need to know how to ask the right questions!!
• We are looking for people that are reliable and can problem solve!!!
Parent Function Project
• 7 Functions to graph and find key information
• Due on test day (9-19/20)
• Counts ½ of the test grade
• Lots of resources
• Websites
• Textbook
• Some time will be given to work on these in class and also ask questions.

### Unit 1

Solving Linear Equations

Objectives
• I can solve equations with one variable
Vocabulary Terms
• Variable
• Like Terms

### Variable

Any letter or symbol used to represent a number that is not known

### Like Terms

Terms that have the same variables raised to the same powers

Like Term Activity
• Group the like terms together in your notes.
• Now that they are grouped, COMBINE your LIKE Terms.
Solving Equations
• Let’s see what we recall from Algebra-1 to solve an equation for a missing variable??
What really Happened?
• What steps really happen to solve that equation?
Equations??
• What happens to a term anytime you move it to the other side of the = ?
Solving Equations
• Get the variable terms together on the left side of the equation
• Move all the numbers to the other side of the equation.
• LAST step is always DIVISION (or Multiply by a reciprocal)

2.

x + 1 = 4

x + 1 = 4

x = 3

Multiply each side by , the reciprocal of .

x = – (3)

The solution is 5.

GUIDED PRACTICE

Solve the equation.

SOLUTION

Write original equation.

Subtract 1 from each side.

x = – 5

Simplify.

In Class Practice
• Work with your partner and solve the first 4 problems on the activity.
Word Problems
• The bill for the repair of a car was \$420. The cost of parts was \$240. The cost of labor was \$45 per hour. Write an equation and then solve for how many hours the repair took.
Solution:
• Total cost: \$420
• Parts: \$240
• Labor: \$45 per hour
• Possible Equation:
• Let “x” represent the # of hours
• 240 + 45x = 420
• x = 4 hours
In Class Practice
• Work with your partner and solve the last word problem on the activity.
No Variables

No Solution

All Real Numbers

2x + 4 = 2x + 4

When you subtract the 2x you end up with

4 = 4

This is true

Meaning, that every value of “x” will make this equation valid

• 2x + 4 = 2x – 3
• When you subtract the 2x you end up with
• 4 = -3
• This is not true
• Meaning, there is no value for “x” to make this equation valid.
Homework
• WS 1-1: Solving Equations
• Signed Syllabus if not already returned
• Work on Parent Function Project
