# Week 15- pre calc 11

This week in PreCalc 11 we revisited the idea of rational expressions and learned how to add together rational expressions with variables in the denominator. for example: when we add the rational expressions together the denominator needs to be the same so we take a common factor of the two denominators. And we always need […]

# week 14- pre calc 11

This week in pre calc 11 we learned how to determine the difference between and absolute value graph and reciprocal value graph. we know that an absolute value graph cannot have any negatives at all because when a number is in the absolute value symbol even if it is negative it must change to positive, […]

# week 13- pre calc 11

This week in PreCalc 11, we learned how to graph absolute value functions. An Absolute Value Functions is a function that has an expression within absolute value symbols. We were taught before that Absolute Values, was when the number is between the absolute value symbols must come out a positive. Example, | -2 | = […]

# week 12 – pre calc 11

This week in Pre Calc 11, We learned how to solve systems of equations using substitution. A way to solve a linear system or quadratic system or both is to use the substitution method. We do this by substituting a y-value in an equation with the other. to start you first substitute y in the […]
