Answer:
(x + 1)² + (y + 5)² = 48
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 1, - 5) and r = 4, so
(x - (- 1))² + (y - (- 5))² = (4 )², that is
(x + 1)² + (y + 5)² = 48 ← equation of circle
value of x lies in number line as and
.
<u>Step-by-step explanation:</u>
Here , we need to tell where on a number line the value of x is for expression . Let's find out:
We know that for a Modulus function the value inside modulus is both positive & negative depending on value of x , So
x is positive :
Equation will be
⇒ , That means all numbers which are greater than 1 are included i.e. from 1 to 10 , where 1 is not included as x is strictly greater than 1 .
x is negative :
Equation will be
⇒
⇒
⇒ , That means all numbers which are less than -1 are included i.e. from -1 to -10 , where -1 is not included as x is strictly less than -1 .
Therefore , value of x lies in number line as and
.
