Can someone find x for these questions
Maurinko [17]

Answer:

8, 36, -12

Step-by-step explanation:

Q2

41 = 8x - 23

8x = 41 + 23

8x = 64

x = 8

Q4

11 = x/2 - 7

22 = x - 14

22 + 14 = x

x = 36

Q6

3(x - 8) = -60

x - 8 = -20

x = -12

Can someone please help me solve this?
aleksklad [387]

Answer:

centre = (-5, -4)

radius = 7.42

Step-by-step explanation:

The general form for center-radius is

(x - h)² + (y - k)²= r²

Center = (h, k)

Radius = r

Rearrange the equation.

(x² + 10x) + (y² + 8y) - 14 = 0

Add 14 on both sides.

(x² + 10x) + (y² + 8y) = 14

(10/2)² = 25

(8/2)² = 16

Add 25 and 16 to both sides.

(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16

Factor left side of the equation.

(x+5)² + (x+4)² = 55

(55) = (7.416198)²

(x+5)² + (x+4)² = 7.42²

The radius is 7.42.

The centre is at (-5, -4).
