1/-x*5y/-8
-1/x × (-5y/8)
5y/8x
Answer:
the correct solution is -8x + 9.
Step-by-step explanation:
diameter (d) = 2 · r
Circumference (C) = 2 π · r → C = π · d → d = 
Answer:
<em>Choice D.</em>
Step-by-step explanation:
Vertical line test for functions:
If a vertical line drawn anywhere on the graph intersects the graph in more than one point, it is not a function.
If you draw a vertical line passing through any point between x = -4 and x = 4, the line will intersect two points on the circle. The relation fails the vertical line test. That shows that this relation is not a function.
