2. The following five problems are designed to help you make sure that you have internalized the material in this presentation. We suggest that you treat these problems as if they were a test. © 2007 Herbert I. Gross After you have worked on these problems, check your answers against the ones that are given. Then read through our solutions and commentary in the Problem/Solution PowerPoint Presentation. next

3. Problem #1 © 2007 Herbert I. Gross next Write… y = 3x – 2(4 – x) in the form y = mx + b.

4. Problem #2 © 2007 Herbert I. Gross next For what value of x is it true that… 3x – 2 (4 – x) = 147

5. Problem #3 © 2007 Herbert I. Gross next If… - y = 8x – 5, what is the rate of change of y with respect to x?

6. Problem #4 © 2007 Herbert I. Gross next If… 3y = 12 – 2x, what is the rate of change of y with respect to x?

7. Problem #5a © 2007 Herbert I. Gross next If a 20 pound slab of cheese is sliced into packages, each of which contains 2 / 3 of a pound of cheese: how many packages will there be?

8. Problem #5b © 2007 Herbert I. Gross next With respect problem #5a: write the linear equation that relates the number of pounds of cheese (y) that are left after x packages have been sold.
