Equation: Product of 4 and 6 is means
Multiply 4 * 6 = n n=24
Equation: Sum of 5 and 8 is means
Add 5 + 8 = n n=13
Equation: Difference between 12 and 7 is means
Subtract 12-7 = n n=5
Equation: Quotient of 10 and 5 is means
Divide 10/5 = n n=2
Expression: the product of 3 and a number
3n no equals sign
Expression: the sum of 6 and a number
6+n no equals sign
Expression: the quotient of a number and 5
n/5 no equals sign
-4(5x + 6y -3)
-20x -24y +12
Distribute -4(n + m - s)
Multiply each item inside the parentheses by the number outside the parentheses using principles of +/- signs
-4n -4m +4s
Simplify - combine like terms
14x - 3y -22 + 3x + 4y - 16
17x + 1y - 38
Equation Standard Form Ax + By = C
2x = 4y + 10
2x - 4y = 10
Slope = rise/run (4 , 7) (6 , 9) m = y2 - y1 / x2 - x1 (x1, y1) (x2, y2)
(4 , 7) (6 , 9)
m = 9 - 7 / 6 - 4 = 2 / 2 = 1
y = mx + b m is the
m = slope
y = mx + b b is the
b = y intercept, the value of y when x is 0
0,b
Absolute Value of a number is
|n|
always positive
the distance a number is from zero
|-2| and |2| is
2
Solve | x - 3| = 10
|x - 3| = 10 x = 10 + 3 x = 13
|x - 3| = -10 x = -10 + 3 x = -7
