X^2 – 12x + 36 = 0
(x-6)(x-6)=0
x=6 x=6
Not a solution
x^2 + 12x – 36 = 0
Doesn't factor
Not a solution
x^2 + 36 = 0
x=√-36
Not a solution
x^2 – 36 = 0
(x-6)(x+6)= 0
x=6 x=-6
Solution
ANSWER: The equation with solutions of x=6 and x=-6 is the last choice: x^2 - 36= 0.
Hope this helps! :)
Answer:
Step-by-step explanation:
The equation representing the price of gas for the years after 2000 is expressed as
y = 1.26(1.10)^x
Where x = 0, 2, 4, 6, 8, and 10 represent these years : 2000, 2002, 2004, 2006, 2008, and 2010, the table would be
1) x = 0(2000)
y = 1.26(1.10)^0
y = 1.3
2) x = 2(2002)
y = 1.26(1.10)^2
y = 1.5
3) x = 4(2004)
y = 1.26(1.10)^4
y = 1.8
4) x = 6(2004)
y = 1.26(1.10)^6
y = 2.2
5) x = 8(2006)
y = 1.26(1.10)^8
y = 2.7
6) x = 10(2008)
y = 1.26(1.10)^10
y = 3.3
Simplified expression is 11y² + 6x - 13
Step-by-step explanation:
- Step 1: Simplify 5y² + 3y - 13 + 6x - 3y + 6y²
5y² + 3y - 13 + 6x - 3y + 6y² = 11y² + 6x - 13
10/12 and 3/12 6 x 2=12, what you do to the bottom you do to the top 5 x 2= 10 4 x 3=12, what you to the bottom you do to the top 1 x 3=3
Answer:
D.
Step-by-step explanation:
The problem is clearly addition, so we can rule out B and C. Associative property is the movement of the parentheses, whereas commutative property is the movement or reorganization of the numbers. The parentheses moved in this problem, so it is associative. I suggest reviewing these properites, they come in handy later and are good to know :)
