Answer:
![B' = (-3, -15)](https://tex.z-dn.net/?f=B%27%20%3D%20%28-3%2C%20-15%29)
Step-by-step explanation:
Given
![A = (-3,-1)](https://tex.z-dn.net/?f=A%20%3D%20%28-3%2C-1%29)
![A' = (-9,-3)](https://tex.z-dn.net/?f=A%27%20%3D%20%28-9%2C-3%29)
![B = (-1,-5)](https://tex.z-dn.net/?f=B%20%3D%20%28-1%2C-5%29)
Required
Determine the coordinates of B'
Since A' is the image of A; we need to first calculate the scale factor using
![A' = A * Scale\ factor](https://tex.z-dn.net/?f=A%27%20%3D%20A%20%2A%20Scale%5C%20factor)
Make Scale Factor the subject
![Scale\ Factor = \frac{A'}{A}](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%20%5Cfrac%7BA%27%7D%7BA%7D)
Substitute values for A' and A
![Scale\ Factor = \frac{(-9,-3)}{(-3, -1)}](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%20%5Cfrac%7B%28-9%2C-3%29%7D%7B%28-3%2C%20-1%29%7D)
Factorize the numerator
![Scale\ Factor = \frac{3 * (-3,-1)}{(-3, -1)}](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%20%5Cfrac%7B3%20%2A%20%28-3%2C-1%29%7D%7B%28-3%2C%20-1%29%7D)
![Scale\ Factor = \frac{3 * 1}{1}](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%20%5Cfrac%7B3%20%2A%201%7D%7B1%7D)
![Scale\ Factor = 3](https://tex.z-dn.net/?f=Scale%5C%20Factor%20%3D%203)
The coordinates of B' is then calculated as follows:
![B' = B * Scale\ Factor](https://tex.z-dn.net/?f=B%27%20%3D%20B%20%2A%20Scale%5C%20Factor)
Substitute values for B and Scale Factor
![B' = (-1,-5) * 3](https://tex.z-dn.net/?f=B%27%20%3D%20%28-1%2C-5%29%20%2A%203)
![B' = (-3, -15)](https://tex.z-dn.net/?f=B%27%20%3D%20%28-3%2C%20-15%29)
Answer:
-1 1/6
1 11/16
1 5/6.
Step-by-step explanation:
-5 5/6 ÷ 5
= -35/6 * 1/5
= -7/6
= - 1 1/6.
-4 1/2 ÷( -2 2/3)
= -9/2 / -8/3
= -9/2 * -3/8
= 27/16
= 1 11/16.
-6 7/8 ÷ (-3 3/4)
= -55/8 / -15/4
= -55/8 * -4/15
= 11/6
= 1 5/6.
Do a ratio tall over shadow. How tall is tree / shadow. How tall is person / shadow then cross multiply. X/7.5 =5/3. 37.5=3x. Divide by 3 answer 12.5
