What are the coordinates of the center of a circle whose equation is (x + 7)2 + (y – 5)2 = 16?
Dafna11 [192]
Hi there! The answer is ( - 7, 5)

The standard form of the equation of a circle is the following:
(x - a) {}^{2}  + (y - b) {}^{2}  = r {}^{2}

In this equation r represents the radius of the circle and the point (a, b) is its centre.

Therefore, the centre of the circle
(x + 7) {}^{2}  + (y - 5) {}^{2}  = 16
is the point ( - 7, 5).

Solve each question and check your solution <br> -2(3x-4)=4(x+3)+6
agasfer [191]

Answer:

x = -1

Step-by-step explanation:

-2(3x-4)=4(x+3)+6

Distribute

-6x +8 = 4x +12 +6

Combine like terms

-6x +8 = 4x+18

Add 6x to each side

-6x+6x +8 = 4x+6x +18

8 = 10x+18

Subtract 18 from each side

8-18 =10x+18-18

-10 = 10x

Divide each side by 10

-10/10 = 10x/10

-1 =x
