Answer:
The answer is
<h3>center = ( - 7 , - 1)</h3><h3>radius = 6</h3>
Step-by-step explanation:
The general equation of a circle is given by
<h3>x² + y² + 2gx + 2fy + c = 0</h3>
where the center of the center of the circle is given by
<h3>( - g , - f)</h3>
From the question the equation is
x² + y² + 14x + 2y + 14 = 0
Comparing with the general equation above we have
2g = 14 2f = 2
g = 7 f = 1 c = 14
So the center of the circle is
<h3>( - 7 , - 1)</h3>
The radius of a circle is given by
where
g = 7
f = 1
c = 14
Substitute the values into the above formula
That's
we have the final answer as
<h3>radius = 6</h3>
Hope this helps you
The expression is given to be:
Recall the multiplication rule of exponent given to be:
Therefore, we can simplify the numerator to be:
Hence, the expression becomes:
Recall the division rule of exponent given to be:
Therefore, the expression becomes:
Evaluating the answer, we have:
Therefore, the answer is:
Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)
60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges
Answer:
Step-by-step explanation:
We are given equation as
Since, we have to write equation in slope-intercept form
so, we can use slope-intercept formula
where m is a slope
b is y-intercept
so, we can write our equation in this form
Distribute 3
Subtract both sides by 4
So, slope-intercept form of equation is
