Answer:
4
Step-by-step explanation:
The rule of dilation is
This means that each distance QX' is equal to
where X is initial point and X' is its image after dilation.
Since QA=6, then

H(x) = -5x - 10
h(-2) = -5(-2) - 10
h(-2) = 10 - 10
h(-2) = 0
The altitude is the mean proportional between the left and right parts of the hyptenuse

Answer: 14.1
Answer:
B(-2, -7)
Step-by-step explanation:
Midpoint is (0, -3)
A(x₁, y₁) B(x₂, y₂)
A(2, 1)




∴ B(-2, -7)
