Step-by-step explanation:
Given
x² - 2x - 4 = 0 ( add 4 to both sides )
x² - 2x = 4
To solve use the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 4 + 1
(x - 1)² = 5 ( take the square root of both sides )
x - 1 = ± 
( add 1 to both sides )
x = 1 ± , thus
x = 1 + or x = 1 -
Answer:
Step-by-step explanation:
5/9m=15
9/5x5/9 cross that out and you have to do 15/1x9/5 which is 3/1x9/1 which is 27 muffins.
multiple 9/5 by 5/9 because of the recipricol which evens out that number because it becomes whole. then do the same thing to the 15 and you simplify both the fractions then multiply which creates 27, or just look at 5/9 and 15/x 15 divided by 5 is 3 and 3 times 9 is 27 tada!!
Answer:
Whole numbers, repeating decimals, and decimals that never end
Step-by-step explanation:
It would be c or 2 because x is your slope therefore your x-intercept.
so I would say c
