The slope of the line is: y= 2x+2
We can get the circumference of any circle in terms of the radius with this formula. C = 2

r.
Where r is the radius of the circle.
And we will use 3.14 for

.
Plug in all the values.
C = 2 * 3.14 * 2
C = 12.56
So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.
Answer:
Molly paid for each song $1.5
Step-by-step explanation:
Let
x ------> amount that Molly paid for each song
we know that
The amount that Molly paid for each song multiplied by 8 is equal to the gift card value
so
The linear equation that represent this problem is

Solve for x
Divide by 8 both sides


Molly paid for each song $1.5
We have been given that a line
passes through the point (10, 3) and is parallel to the line
. We are asked to find the y-intercept of the line.
First of all we will rewrite our given equation in slope-intercept form as:




We know that slope of parallel lines is equal, so slope of parallel line to our given line would be
.
Now we will use slope-intercept form of equation to find y-intercept.
, where,
m = Slope,
b = The y-intercept.
Let us substitute
and coordinates of point
in above equation as:





Therefore, the y-intercept is 7 and our required equation would be
.
