What is the equation of a line that is parallel to  −3x+4y=4 and passes through the point (4,0)?
Genrish500 [490]
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.

Find the radius of a circle with an area of 380 in².
Likurg_2 [28]

Answer:

11 inches

Step-by-step explanation:

The area of a circle can be found using:

a=\pi r^{2}

We already know that the area is 380, so we can substitute 380 in for a.

380=\pi r^2

Now, we need to find the radius. To do this, we need to get r by itself

First, divide both sides by pi

380/\pi =\pi r^2/\pi

120.95775675=r^2

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

\sqrt{120.95775675}=\sqrt{r^2}

10.9980796846=r

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