7/9 because if you simplify 21/27 you have to divide it by something that can go into both equally, which in this case is 3
Answer:
the third choice. x>_-6
Step-by-step explanation:
1. When you have the square root of (x+6), it shifts the graph 6 units to the left.
2. So the x values would start and include -6 and continue growing to the right.
3. So the domain (x values) of the equation is x is greater than or equal to -6
Remember that if lines are parallel, they will have the same slope. Also, the number added or subtracted in the equation is the y intercept, or the y value when the x=0. They gave you the point (0,-7) so really, they just gave you the y intercept. How nice!! That means you just use the same slope as the original and then add -7 to it to get your equation. With that knowledge, you can now easily identify the correct answer!!
