When it comes to constraints on real-world systems, nothing does the trick like linear algebra. Here, a factory makes and packages salsa.

How can you factor a polynomial when you don’t even know what the polynomial is? Well, you can’t, but you can know a few things.

Graphing the solution to a system of linear inequalities is likely to come up on the PARCC test in algebra 1. Are you ready?

Measures of central tendency and the spread of data, including outliers, will come into play as students take the PARCC test in algebra 1 this spring.

How would you figure out (and explain) when one car, traveling at a given speed, will overtake another car that had a head start?

Adding, multiplying, & subtracting polynomials is tested, quite thoroughly, on the PARCC algebra 1 test, used in Md. and some middle schools in IL.

Solving equations for a variable of interest is required in algebra 1 on the PARCC test (and in the Common Core). Students find the radius of a circular pool.

Is a given ordered pair on the graph of a function? Algebra 1 students should be able to figure it out, esp. those who will take the PARCC test this year.

The zeros of a polynomial are the *x* values when the polynomial equals 0. Do you know how to find the zeros?
