Which ordered pair is the solution to the system of equations?
Tcecarenko [31]
The best way to answer this item is to use the Substitution method. Substitute the value of y from the first equation to the y of the second equation such that the second equation becomes,

     -4x + 3(x - 4) = -3

Simplifying the equation,
    -x = 9

Dividing both sides by -1 gives an answer of,
   <em>x = -9</em>

Then, substitute the value of x in the first equation.
    y = -9 - 4
   <em> y = -13</em>

The answer to this item is letter B.

\huge{\underline{\boxed{\tt{Answer:}}}}

Let AB be a chord of the given circle with centre and radius 13 cm.

Then, OA = 13 cm and ab = 10 cm

From O, draw OL⊥ AB

We know that the perpendicular from the centre of a circle to a chord bisects the chord.

∴ AL = ½AB = (½ × 10)cm = 5 cm

From the right △OLA, we have

OA² = OL² + AL²

==> OL² = OA² – AL²

==> [(13)² – (5)²] cm² = 144cm²

==> OL = √144cm = 12 cm

Hence, the distance of the chord from the centre is 12 cm.
