Answer:
You need a graph, but x = 3/2 and y = -9/2
Step-by-step explanation:
You need a graph to plot points. Here is a graph:
https://www.wolframalpha.com/input/?i=Plot+the+point+(3%2F2,-9%2F2)
Anyways, 3/2 = 1.5 and -9/2 = -4.5, so that is why it shows those points on the graph.
1.5 is on the x-axis while -4.5 is on the y axis.
Answer:
18 inches and 57 inches
Step-by-step explanation:
The diameter and the circumference of a circle are proportionate to each other.
The circumference of a circle will always be the diameter times 
. We know this because the circumference of a circle is represented as
Since the diameter is twice the radius, we multiply the radius by 2 - there's already a 
in this equation, so 
.
1st option: 
, this is close to 57 so it's reasonable.
2nd option: 
, this isn't close to 28 at all.
3rd option: 
, this isn't close to 80 at all.
So the 1st option is reasonable.
Hope this helped!
