Answer:
(a)25.12 (b)$18.84
Step-by-step explanation:
(a) The circumference or perimeter of a circle is . Since we know that the radius of the garden is 4 we find that the circumference of the garden is
, but we can round
to 3.14, which gives us C 25.12 feet of fencing.
(b) We can plug in the circumference of the circle which we found in the first question into the equation which gives us
or $18.84.

Answer:
See below.
Step-by-step explanation:
So we started off with the equation:
And we subtracted x from both sides to acquire:
Now, this is essentially slope-intercept form. Recall that the slope-intercept form is:
Where m is the slope and b is the y-intercept.
If we rearrange our equation:
And put some parentheses:
We can see that this is indeed slope-intercept form.
And we can see that m is -1 and b is 2.
In other words, the slope is -1 and the y-intercept is 2.
