Answer:
option c (19.2, -6.7) is correct
Step-by-step explanation:
Mid point - it is the middle point of a line segment. It is equidistant from both endpoints and it is the centroid both of the segment and of the endpoints.
if (
) and (
) are the end points of a line segment then mid point is
given by :- 
according to question :
given : end point T(-16.8, 31.7) and mid point M(1.2, 12.5)
let coordinates of another end point S (a, b)
therefore, using mid point formula
1.2 = (-16.8 + a)/2
2.4= (-16.8 + a)
19.2 = a
and,
12.5 = (31.7 + b)/2
25 = 31.7 + b
-6.7 = b
so the option c (19.2, -6.7) is the correct answer

Here is my answer. I hope it is helpful.
The additive inverse of an expression is composed of terms which bear the opposite sign of the equivalent functions such that when the two functions are added, the sum is zero. In this case, the additive inverse of +4x is B-4x.
<span>2. a) 4x + (4 -x) = 0
</span> 4x + 4 -x = 3x + 4 is not equal to 0.
<span> b) 4x + (-4x) = 0 additive inverse
</span> c) <span>4x + (1/4x) not equal to zero should use multiplicative inverse
d) </span><span>4x + x - 4 = 5x - 4 is not equal to zero</span>
