What You Need To Know...

 

Solve linear equations in one variable including simplifying algebraic expressions.

  1. The benchmark will be assessed using MC (Multiple Choice) and FR (Fill in Response) items.

  2. Items may include applications of commutative, associative, distributive, and identity properties.

  3. Items may have variables on both sides of the equal sign.

 

MA.912.A.3.1 Solving Linear Equations

Example One

Andrew plotted a set of points on the coordinate grid shown below.  All of the points have integer coefficients.

Which of the following points could be removed so that Andrew's graph represents a function?

  1. (-4, -3)

  2. (-2, 1)

  3. (0, 0)

  4. (2, -2)

Example Two

 

The function shown below is used to convert a temperature, x, in degrees Fahrenheit (°F), to a temperature, f(x), in degrees
Celsius (°C).

 

 

 

 

 

Micah wanted to convert today's high temperature of 77°F to °C.  What is today's high temperature in °C?

Example Three

 

For one child, a childcare facility charges $300 per month for preschool and $3.50 per hour for each hour of childcare after preschool. The function below can be used to determine f(h), the monthly fee for childcare and preschool, where h represents the number of hours spent in childcare after preschool.

                                                    f(h) = 300 + 3.5h
 

If the one-month charges for one child totaled $637.75, what was the total number of hours the child spent in childcare after preschool?
