So you have to first put put the equation in slope-intercept form.
-3x+4y=4
+3x +3x
_______________
4y=4+3x
then you divide 4 by 4 and then divide 3x by 4 and you should get y=1+3/4x
then you plug in x and only x so that you can find y and then do the same once you find y
y=1+ (4)3/4
y= 1+3
y=4
then plug in y and solve for x
4= 1+ 3/4x
subtract 1 from both sides
3=3/4x
divide both sides by 3/4
and x=4
so then you find b and put it all in a equation.
Step-by-step explanation:
option C is the correct answer of this question
Answer:
11 inches
Step-by-step explanation:
The area of a circle can be found using:

We already know that the area is 380, so we can substitute 380 in for a.
380=
Now, we need to find the radius. To do this, we need to get r by itself
First, divide both sides by pi

120.95775675=r^2
Since r is being squared, we need to take the square root of both sides

10.9980796846=r
If we round to nearest whole number, our radius is 11 inches
