Answer:
Step-by-step explanation:
The slope-intercept form is 
, where m is the slope of the line and c is where the line crosses the 
-axis.
To calculate 
we can use the formula 
where 
is the difference in between two points and 
is the difference between 
.
Information we can get from the graph given: 
. Since 
is the point at which the line crosses the -axis.
To find let's get two points from the graph.
Point 1: 
Point 2: 
Now use the equation .
.
Now we have and , let's put them back into the general equation.
The circumference is found by multiplying the diameter by PI.
Circumference = 13 inches x 3.14 = 40.82
Rounded to the nearest tenth = 40.8 inches.
Answer:
<h2>x = 10</h2>
Step-by-step explanation:
<h3>Since BE is perpendicular bisector AE=ED</h3><h3>Substituting we have:</h3><h3>3x + 5 = x + 25 solving for x</h3><h3> x = 10</h3><h3 />
