The x-value of the coordinates of point C is -12.

Step-by-step explanation:

Let be A = (8, 4) and B = (-2, 7) , which is midpoint of segment AC. The location of point C is obtained from the midpoint formula, that is:

$B = \frac{1}{2}\cdot A + \frac{1}{2}\cdot C$

$2\cdot B = A + C$

$C = 2\cdot B - A$

$C = 2\cdot (-2,7)-(8,4)$

C = (-4,14)-(8,4)

C = (-4-8,14-4)

C = (-12,10)

The x value is the first component of the ordered pair, that is: x = -12 . The x-value of the coordinates of point C is -12.

Answer : 8/45

To find this answer all you have to do is multiply fractions. Multiply the numerator by the numerator and the denominator by the denominator.

4 x 2 = 8 5 x 9 = 45

This gives you 8/45.
