It's already a square; we don't need to add anything to complete the square.
That's a vertex at x = -1. The corresponding y is y=0.
Answer: Vertex at (-1,0)
As for the other questions cut off there, the axis is the vertical line x = -1 and the range is y ≥ 0.
Answer: Choice A
The second fraction should not have been multiplied by 9
This is because 1/9 already has the LCD in the denominator. LCD stands for lowest common denominator.
The first fraction 2/3 does not have 9 in the denominator, which is why they multiplied top and bottom by 3
2/3 = (2*3)/(3*3) = 6/9
After each fraction has the same denominator (9), you can add the numerators to place over the LCD like so
6/9 + 1/9 = (6+1)/9 = 7/9
This means,
2/3 + 1/9 = 6/9+1/9 = 7/9
Answer: 14
Step-by-step explanation:
when you multiply 9 by 14 you get the answer 126.
So it takes 14 nines to get 126.
