math 10-week 15

This week we learned how to find a solution by using substitution As an example i will find the solution to 5x-3y=27 and 2x+y=2 the first step is to use one of the equations and isolate one of the variable… Continue Reading →

math 10-week 14

This week we learned how to tell if two lines will be parallel, coincidence or have one intercept point. parallel: you will know if two lines are parallel by looking at there slope, if they are the same the line … Continue Reading →

Math 10-Week 13

This week we learned 3 different ways to write equations of linear relations General form ax+by+c+0 general form is usually considered useless because it does not give slope and X and Y are on the same side of the equation… Continue Reading →

Math 10-week 11

how to find the length of an oblique line To find the length of an oblique line you have to use the Pythagorean theorem. to do this the formula is a^2 + b^2 = c^2 A= horizontal line of triangle… Continue Reading →

Math 10-week 12

This week we learned about slope. to find slope you use the formula rise over run rise = y1-y2 run=x1-x2 So if you had two points on a graph ex (8,6) (2,3) you would subtract y1 by y2 over x1… Continue Reading →

Math 10- Week 10

This week we learned about function notation. Function notation looks something like this: F(x)= 6x-9 Function notation is another way of showing the value of y in a function because F(X)= Y So if F(6) Then our equation would be… Continue Reading →

Math 10-Week 9

Functions A function is a type of relation where each input has only one output example X    Y 3     6 4      8 2      9 This is a function because every input has only one… Continue Reading →

Math 10-Week 8

Finding rules with Input and output tables Ex X       Y 1       9 2        12 3         15 4         18   To find a rule for this table you… Continue Reading →

Week 6-Math 10

Factoring “ugly trinomials” This method is for when the sum of the 2nd term and the product of the 3rd arent made with the same factors. Ex 2x^2 + 7x + 6 look at the factors of the first and… Continue Reading →
