Transformations

Translation- slide along a straight line
Rotation- turn about a fixed point
Reflection- mirror image

Know how to do and describe each of them
plot (-4, 6) on this grid. Sorry if the grid is too small.

(sorry i don't know how to put roman numerals sign)

(+,+) = Quadrant 1

(-,-)= Quadrant 3

(-,+)= Quadrant 2

(+,-)= Quandrant 4

2j x 3= 36

Variable-(j is the variable)  a letter that represent a unknown number.

Expression-(2j x 3) any single number or variable or a combination of operations.

Constant-(3 is the constant) a number that does not change, increases or decreases, the value of an expression.

Numerical coefficient-(2 is the numerical coefficient) a number that multiply a variable.


Equation- mathematical statement with two expression that have the same value. (a scale)

eg. x+3=3 , y-7=(4) , 3a-2=a+2 , b=4






Identify the value of variable.

 Isolate the variable:

Use opposite operation:

Add - Subtract
Subtract - Add
Multiply - Divide
Divide - Multiply


Remember, when did something on the left side you have to do the same thing in the right side.
 

 

Remember to always check your answer.

Number of the Day (8-14)

Number of the day: 1234.567

8. Power- A base with an exponent is a power.
    

- Write a power using the digit  in the 100th (1234.567) place as the base and the digit in the 10s (1234.567) place as the exponent. 6³

9. Power in factor form
- 6 x 6 x 6= 216
- Six ,three times...not  six times three.

10. Cube - means three dimensional (3D)

- L x W x H  = N(umber) x N x N = N³
-  Cube the digit in ones place - 4 x 4 x 4 = 4³

11. Squared - means it has two dimensional (2D)
- L x W = N(umber) x N = N²
- Square the digit in hundreds place - 2 x 2 = 2²

12. Use a calculator,
- 1234.567 ÷ 3.55 = 347.7653521

- Rounding numbers...

• Look at the given nearest place value...
• Make the numbers that end in 1 through 4 into the next lower number that ends in 0. For example 74 rounded to the nearest ten would be 70.
• Numbers that end in a digit of 5 or more should be rounded up to the next even ten. The number 88 rounded to the nearest ten would be 90.

- Round it to the nearest 100th - 347.8

13. Product- is an answers into a multiplication question.

      Digit - a part of a number, a symbol to represent the number.

- Product of all the digits (use a calculator) - 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5040

- Forget about the decimal.

- Remember if there is (are) 0 digit(s) in the number the answer is 0.

14. Prime numbers- numbers with 2 factor, one and itself, not 1 or 3 more.
- 3, 5, 7 are prime numbers of 1234.567


Try this number to practice number 8 - 14: 8749.294

Adding Mixed Numbers

Mixed number is a whole and a proper fraction.
        
          eg. 1 1/4  , 2 1/3, 3 5/6

Improper Fraction- Fraction with a greater numerator than denomenator.

         eg. 6/2, 5/4, 4/3, 12/8
