Answer:

C. 2.25

Step-by-step explanation:

The following information is missing: J is at (-3, 4). K is at (4,-2).

The x value for point L such that JL and KL form a 3:1 ratio is obtained as follows:

m/(m+n)*run + xJ

where ratio m:n givesfraction m/(m+n), run is the distance over x-axis between J and K, and xJ is the x-coordinate of J.

ratio 3:1 means: m/(m+n) = 3/(3+1) = 3/4

run = 4 - (-3) = 7

xJ = -3

Replacing into the equation:

m/(m+n)*run + xJ = 3/4*7 + (-3) = 2.25

Step-by-step explanation:

The equation of a circle in general form is

x² + y² + 2gx + 2fy + c = 0

with centre = (- g, - f) and radius = $\sqrt{g^2+f^2-c}$

Given

2x² + 2y² + 6x - 8y + 12 = 0 ← divide through by 2

x² + y² + 3x - 4y + 6 = 0 ← in general form

Compare like terms

2g = 3 ⇒ g = $\frac{3}{2}$

2f = - 4 ⇒ f = - 2 and c = 6, thus

centre = ( - $\frac{3}{2}$ , 2 ) and

radius = $\sqrt{(3/2)^2+(-2)^2-6}$

= $\sqrt{\frac{9}{4}+4-6 }$ = $\sqrt{\frac{1}{4} }$ = $\frac{1}{2}$
