Answer:
Step-by-step explanation:
B= -20+45/56
B=-20.80
Price, when purchased online: 1.30($160)
Price, when purchased at superstore: 1.40($160)
Difference in prices: 1.40($160) - 1.30($160) = 0.10($160) = $16
A higher markup brings a higher retail price.
Answer: i feel that the coorect answer is b
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
