What is the domain of the function y= (square root) x+6-7

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

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
