Given parameters:
Midpoint of AB = M(3, -1)
Coordinates of A = (5,1)
Unknown:
Coordinates of B = ?
Solution:
To find the mid point of any line, we use the expression below;
and 
where 
and 
= coordinates of the mid points = 3 and -1
x₁ = 5 and y₁ = 1
x₂ = ? and y₂ = ?
Now let us input the variables and solve,
3 = 
and -1 = 
5 + x₂ = 6 -2 = 1 + y₂
x₂ = 1 y₂ = -2 -1 = -3
The coordinates of B = 1, -3
80,000 per year....there are 12 months in a year
80,000 / 12 = 6666.67 per month
Answer:
Hope that help the answer is 300
Step-by-step explanation he drives for 3 hours at a rate of 80 km per hour, multiply:
Now we need to find how far he goes in 45 minutes. There are 60 minutes in an hour, so write and simplify:
45 is three quarters of an hour, so multiply that by 80 km per hour:
Add the distances together:
At a rate of 80 km per hours, in 3 hours and 45 minutes, Tim drives 300 km.
Finito.

Answer:
x(x + 1)
Step-by-step explanation: This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1)
