Answer:(x + 6) + (y + 2)^2 = 13

Step-by-step explanation:

The centre of the circle is halfway along the diameter = (-6, -2)

r^2 = (-4 - -6)^2 + ( 1 - -2)^2 = 2^2 + 3^2 = 13

So circle equation is (x - -6)^2 + (y - -2)^2 = 13

90 x= 81 + 25 I need help ?

charle [14.2K]

Answer:

$x = \frac {53} {45}$

Step-by-step explanation:

Step 1: Combine on the right side

$90x = 81 + 25$

$90x = 106$

Step 2: Divide both sides by 90

$\frac {90x} {90} = \frac {106} {90}$

$x = \frac {106/2} {90/2}$

$x = \frac {53} {45}$

Answer: $x = \frac {53} {45}$
