The required circle will have a radius of 3 units and centre at (1, -2)

<h3>Equation of a circle</h3>

The standard equation of a circle is expressed as shown;

(x-a)^2+(y-b)^2 = r^2

where

(a, b) is the centre of the circle

r is the radius of the circle

Given the equation of the circle below;

(x − 1)^2 + (y + 2)^2 = 9

(x − 1)^2 + (y + 2)^2 = 3^2

Find the centre and radius

centre = (1, -2)

radius = 3

This shows that the required circle will have a radius of 3 units and centre at (1, -2)

If a number added to five is divided by the difference of the number and two, the result is three-fourths. Find the number.
alexandr1967 [171]

Answer:

x = - 26

Step-by-step explanation:

Let the number be x.

According to the question,

\frac{x+5}{x-2} = \frac{3}{4}\\

Cross multiplying 4 & 3 gives :-

4(x+5)=3(x-2)

And solving this eqn. gives :-

4(x+5)=3(x-2)\\=> 4x+20=3x-6\\=>4x-3x=-20-6\\=>x=-26

Verification :-

(putting the value of x = -26 )

\frac{x+5}{x-2} \\\\=>\frac{-26+5}{-26-2} \\\\=> \frac{-21}{-28} \\\\=>\frac{21}{28}

Reducing  \frac{21}{28}  by 7 gives  \frac{3}{4} .
