Week 17- Math 10 -Number and Money Applications
NUMBER AND MONEY APPLICATIONS
- step 1: within the question you will need to find what X and Y are supposed to represent. With this information you will state the variables
- step 2: read the question carefully and decide what your two equations will be. usually in a number problem the word is will be the equal sign.
- step 3: solve the equations fully and check your work
ex:
Week 14- Math 10 – general form
This week i learned how to turn an y intercept equation into a general form equation
step 1: with the y intercept equation Y= mX+b you will move the Y to the other side
step 2: This will Give you the answer 0= -Y+mX+B and this is your answer
example:
Week 15- Math 10 – DESMOS Wonky initials
Week 16- Math 10 – Solving Systems
To solve a system using substitution:
- step 1: choose the most simple equation and isolate a variable on one side
- step 2: insert this equation into the second euquation and solve for the variable
- step 3: with the answer to this question you insert it into either one of the original equations and solve for the variable again
- step 4: check your answer by inserting the variable answers into each equation
ex:
Week 13 – Math 10 – Slope with out a graph
Week 12 – Math 10 – Functions
Functions and relations
- all Functions are relations but not all relations are functions
- For each relation to be a function:
Each input must have have only output
- Visually this means:
There are no two points that are vertically alligned
The graph passes the “vertical line test”

Week 11 – Math 10 – VOCABULARY
Vocabulary on relationships between two quantities
- relation: mathematical relationship with two quantities/values
- Indapendent variable: used for inputs in a relation
- Dependent variable: used for outputs in a relation
- ordered pairs: used to locate points on a cartesian plane
- coordinate: the location of numbers on a grid
Week 5 – Math 10 – Finding a missing side of a triangle
Finding a missing side of a triangle
- To find the missing side of a triangle you need to have the length on one side and an angle.
- you name all the sides and find out if you need to use sin, cos or tang.
- to make the equation you take the angle and put is after your sign then put equals sign for the variable and the length of the side.
- depending on if the length is on the top of the fraction or not you will multiply or divide the length by the sign of the angle.
- once you do this you will have your missing side.
Ex:
Week 3 – Math 10 – Scientific notation
scientific notation
- scientific notation is used represent a very long number in a shortened way. For example 19 000 000 would become 1.9 x 10 to the power of 7
- To convert a large number into scientific notation you count how many times you would have to move the decimal over until you reach the last number. With the number you just came up with you will times the decimal version of the large number with 10 to the power of the fist number you came up with. I find this method a very useful method for me.
an example of a way to do this with positives is shown in this image:
another example but with negatives:
