Answer:
b=-1
Step-by-step explanation:
10(1+3b)=-20
1+3b=-2
3b=-3
b=-1
The endpoints of bar(AB) have coordinates are A(9, 8) and B(-1, -2), so the midpoint is simply the average of x- component of both coordinates and the average of y- component of both coordinates.
A=(x₁, y₁)=(9, 8)
B=(x₂, y₂)=(-1, -2)
The midpoint formula is given below;
is the midpoint of bar(AB).
Answer: 15/24
Step-by-step explanation:
A x B = 5/6 x 3/4 = 15/24
