1st to figure out the translation!!
From (-2,5) to (1,1)
The x values changed 3 values positive that means 3 values right
and the y values changed 4 values negative that nears 4 values down
So the rule is
(x + 3 , y - 4)
(3,2) -- > (6,-2)
The original price for the watch is $120. You can check by subtracting 20% from $120 and you'll get $96.
Answer:
![L = 0.83\ in](https://tex.z-dn.net/?f=L%20%3D%200.83%5C%20in)
Step-by-step explanation:
Given
Width = 1.2 in when Length = 1 in
Required
Determine the length when width = 1 in
First, we need to determine the ratio:
![Ratio = \frac{Width}{Length}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7BWidth%7D%7BLength%7D)
![Ratio = \frac{1.2}{1}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B1.2%7D%7B1%7D)
--- (1)
Let the required Length be represented with L
So:
![Ratio = \frac{Width}{Length}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7BWidth%7D%7BLength%7D)
--- (2)
Equate (1) and (2)
![\frac{1}{L} = 1.2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BL%7D%20%3D%201.2)
Multiply through by L
![L * \frac{1}{L} = 1.2 * L](https://tex.z-dn.net/?f=L%20%2A%20%5Cfrac%7B1%7D%7BL%7D%20%3D%201.2%20%2A%20L)
![1 = 1.2 * L](https://tex.z-dn.net/?f=1%20%3D%201.2%20%2A%20L)
Divide through by 1.2
![L = \frac{1}{1.2}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B1%7D%7B1.2%7D)
