Answer:
The radius of the circle is 3.5 inches.
Step-by-step explanation:
The radius is half the diameter:R= 1/2 d

ANSWER

EXPLANATION
To find the equation in point-slope form, use the formula,

The

is the slope of the line.
We can read from the graph that, the straight line passes through, the points

We can use these two points to find the slope of the line.
The slope can found using the formula,

This means that,




We now use one of the points, say

with the slope to find the equation of the line.
Answer:
Step-by-step explanation:
Since J is the midpoint of HK, then HJ=JK and 3x+5=9x-3 solve for x
6x=8 x=8/6=4/3 so HJ=3x+5=3(4/3)+5=9 = JK HK=2(9)=18
the full segment HK is 18, each half of it is 9 =HJ=JK
