Step-by-step explanation:
Ok but where is the question
Answer:
D. There are points on the graph with the same 
-coordinate but different 
-coordinate.
Step-by-step explanation:
A relation is a function if and only if each element of the range, corresponding with y-axis, is associated with only one element of the domain, corresponding with x-axis. In this case, the graphed relation is not a function, since for all element of the domain, except 0, are related to two distinct elements of the range.
Hence, correct answer is D.
Answer:
6 quarters and 15 dimes
Step-by-step explanation:
6 quarters = $1.50
15 dimes = $1.50
6 quarters + 15 dimes = $3.00
If you mean distance, then we can use the distance formula to find out.
(x - x)² + (y - y)² = d² Distance formula
(-2 + 2)² + (7 + 6)² = d² Substitute the points; remember that when you subtract a negative, you add, and also remember to always subtract in the same direction (with the points (1,2) and (3,4), if you do 1 - 3, then do 2 - 4 and not 4 - 2)
(0)² + (13)² = d² Add
0 + 169 = d² Square
169 = d² Add
13 = d Take the square root of both sides to cancel out the exponent
The distance between (-2,7) and (-2,-6) is 13 units.
Hope this helps!
