Warm up dealt with finding sector area given arc length and central angle. Began algebra review by looking at how to factor a quadratic equation with leading coefficient ≠ 1.

Warm up involved solving a linear system of equations using elimination just like in the video above. Then introduced the 4 ways to think about math: verbally, numerically, algebraically, and graphically. This makes the solution to the system equivalent to the point on the graph where both lines intersect. Applied linear systems in a word problem involving ticket prices. Then showed a visual pattern which led to the development of a linear model which allowed us to calculate the number of items in any step if the pattern continued. Shifted back to quadratic equations and factored to solve others where the coefficients are not 1 and also how to factor a quadratic binomial where both terms have the same variable.

Two visual pattern problems for warm up, leading to both a linear and a quadratic equation. Went over homework then did 2 more problems on the worksheet for extra practice together. Continued algebra review with a look into absolute value equations and developed a procedure for those based on the fact that absolute value considers a number's distance from zero on the number line. Then examined compound inequalities. Finally looked at how to find a polynomial function's zeroes using a calculator's ZERO function.
