Answer:

y= (-3x +14.50) / 8

Step-by-step explanation:

Isolate the 8y

Subtract 3x from both sides

8y = -3x + 14.50

Then, isolate the left to only y

y= (-3x +14.50) / 8

Write the equation of the circle that has a center of (-7, 17) with<br> a radius of V19.
kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at <em>(h,k)</em> and <em>radius r</em> is given by {\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}} . Now , using same concept in this question ;

{:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}

{:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}

<em>This is the required equation of Circle </em>

= 1/12 * 62.8
= 5.23

In short, Your Answer would be 5.23 cm

Hope this helps!
