Answer:
Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
The value of x would be 7
If you do 81 x 9 which equals 729. If you want to check, you do 729 divided by 9 and you get 81.
Answer:
a) The line intersects with the circle once.
b) Tangent
Step-by-step explanation:
We are given the following equation for the circle:
How many times does the line y=-6 intersect with the circle?
We have to find the values of x when
So
Since the line intersects the circle at one point, it is tangent to the circle.
The line intersects with the circle once.
