2 Points<br> What is the center of the circle given by the equation (x+ 5)^2 + (y-8)^2 = 1?

Y_Kistochka [10]

Answer:

(- 5, 8 )

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

(x + 5)² + (y - 8)² = 1 ← is in standard form

with centre (h, k ) = (- 5, 8 )

Answer:

The value of x is $\frac{-2}{5}$ .

Step-by-step explanation:

Given expression is:

$\frac{2}{3}(x-2)=4x$

We have to solve this for x.

First we will multiply both sides of the equation by 3

$3*\frac{2}{3}(x-2)=4x*3$

2(x-2) = 12x

2x-4=12x

Now we will be subtracting 2x from both sides of the equation

2x-2x-4=12x-2x

-4=10x

10x=-4

Dividing both sides by 10

$\frac{10x}{10}=\frac{-4}{10}\\\\x=\frac{-2}{5}$

Hence,

The value of x is $\frac{-2}{5}$ .

Answer:

(-4,16)

Step-by-step explanation:

1/2x+18=5/2+26

1/2x=5/2x+8

-2=8 divided by -2

Equals x=-4

Plug in -4 in one of the equations

1/2(-4)=18= 16
