Answer: Center (0, -8) and Radius = 2

The standard equation of a circle is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius.

You can write the equation as (x-0)² + (y-( -8))² = 2². From this, you can conclude that the center is (0,-8) and the radius is 2.

EXPLANATION

The given inequality is

$|x| \: > \: \frac{3}{2}$

This implies that,

$x\: > \: \frac{3}{2} \: or \: - x\: > \: \frac{3}{2}$

Multiply both sides of the second inequality by -1 and reverse the inequality sign.

$x\: > \: \frac{3}{2} \: or \: x\: < \: - \frac{3}{2}$

The graphical solution to this inequality is shown in the attachment.

Given that the triangles are similar how to find x

alexdok [17]

So if they are similar then just try to figure out which two sides correspond to each other from the first and then the second triangle.

See how in the above example I did 20 and 5 not 20 and 14 or 20 and 3.5 because they do not correspond with one another.

Then figure out, is x on the mama or baby shape and either multiply the number received from all proportions or divide.

Multiply : small to big ( # missing on the bigger one )

Divide : big to small ( # missing on the smaller one)
