I have been teaching high school math for 9 years, and have a lot of experience recording video lessons for my students. I have a master's degree in mathematics, and I love teaching!
When graphing an inequality in two variables, if the inequality is strict use _________ if the inequality is non strict use a_________ mark.
If a graph of a system of linear inequalities cannot be contained in any circle, then it is said to be _________.
Graph each system of inequalities.$$\left\{\begin{aligned}x y & \geq 4 \\y & \geq x^{2}+1\end{aligned}\right.$$
Divide the rational expressions and simplify. State any real numbers that must be excluded from the domain. $$\frac{3 t^{3}-6 t^{2}-9 t}{5 t-10} \div \frac{6+6 t}{4 t-8}$$
Divide the rational expressions and simplify. State any real numbers that must be excluded from the domain. $$\frac{x^{3}+8 x^{2}+12 x}{5 x^{2}-10 x} \div \frac{4 x+8}{x^{2}-4}$$
