Answer:
The domain is x ≥ -7
Step-by-step explanation:
The domain asks what values can x take
We know that the sqrt(x+7) must be ≥ 0
That means the smallest value it can be is zero
x+7 ≥ 0
x ≥ -7
The domain is x ≥ -7
Flip the curve over <em>y</em><em> </em><em>=</em><em> </em><em>x</em><em> </em>then observe what is y when x = -3. You will find that
.

If 2 lines (or line segments) are perpendicular, then the product of their slopes is equal to -1.
Thus, since the given line segments are perpendicular, we have:

.
Multiplying both sides of the equation by 15, we get d=-15.
Answer: d=-15
