This week we were taught how to multiply ugly fractions, we were taught how to do this during grade 9 and 10, but this week we brought in a lot of new concepts. We were taught to eliminate some terms that were the same on top as they were on the bottom and we also learnt about many other tips. Jaxson 🙂

# Blog #13- Recipricals

This week we were taught about reciprocals.

In this blog I will be teaching you how to draw reciprocals for a linear graph.

First step: Plot your points

Second step: figure out the x intercept

Third step: find the -1 and 1 on the y axis

Fourth step: graph the reciprocal

Fifth step: find the points # Blog #12- graphing absolute values.

This week in Pre-Calc 11, we learned how to graph absolute values. These can be applied to both linear and quadratic functions. This task is very easy to complete.

When graphing absolute values the quatratic or linear line will never go below the x intercept.

When the parabola has a absolute value it forms a W shape.

This all happens because absolute value can never be a negative. # Pre Calc 11 – Blog #11

This week we learnt about systems of equations. A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system. The equations in the system can be linear or non-linear.

First step: Factor out the equation

Second step: Find the zeros

Last step: Test the numbers to see if your equation is true
