Start with the standard form of a circle, where
is the center of the circle and
is the radius.

Plug in the known values.

This is the circle's equation in standard form.
Answer:
Solutions are;
x = -8
x = -3.2
Step-by-step explanation:
Here, we want to solve the given equation for x
|(x-4)/(x + 5)| = 4
From what we have, this is an absolute value equation and thus, we are going to have two solutions
These are;
x-4/x+ 5 = 4
x-4 = 4(x + 5)
x-4 = 4x + 20
x-4x = 20 + 4
-3x = 24
x = -24/3
x = -8
secondly;
x-4/x+5 = -4
x-4 = -4(x + 5)
x-4 = -4x - 20
x + 4x = -20 + 4
5x = -16
x = -16/5
x = -3.2
Answer:
Therefore, we conclude that the Jeff must grow 4 inches in order to ride the roller-coaster.
Step-by-step explanation:
We know that: in order to ride a roller coaster,a rider must be greater than 49 inches tall.Jeff is 45 inches tall.
We have the next inequalitythats:

Therefore, we conclude that the Jeff must grow 4 inches in order to ride the roller-coaster.
