Answer:
10 + 5xy = -80
Step-by-step explanation:
10 + 5xy = ?
x = 9 and y = -2
10 + 5xy = 10 + 5(9)(-2)
= 10 - 90
= -80
The coordinate of point V is at (-16, 9)
If Point T(-9,5) lies on the perpendicular bisector of UV, this means that the point divides the line UV into two equal parts
Given the following coordinates
Midpoint T = (-9, 5)
U = (-2, 1)
Required
coordinate of point V
Using the midpoint formulas;

Get the value if x₂ and y₂

Similarly;

Hence the coordinate of point V is at (-16, 9)
