Answer:
![A' =(-y,x)](https://tex.z-dn.net/?f=A%27%20%3D%28-y%2Cx%29)
Step-by-step explanation:
Given
Represent point A as thus;
![A = (x,y)](https://tex.z-dn.net/?f=A%20%3D%20%28x%2Cy%29)
Required
Determine the new position of A, when rotated counterclockwise
The new position will be denoted as A'
When a point is rotated counterclockwise, we start by switching the positions of x and y as follows:
![Pos = (y,x)](https://tex.z-dn.net/?f=Pos%20%3D%20%28y%2Cx%29)
Then, y is negated to give A'
![A' =(-y,x)](https://tex.z-dn.net/?f=A%27%20%3D%28-y%2Cx%29)
Answer:
give me 5 mins and I will tell you the answer
Answer:
$35 x + $25 y ≥ $3200 x ≤ 120
Step-by-step explanation:
Because she needs to write before type the page, so that y≤x
∴ x≤120
$35 x + $25 y ≥ $3200 x ≤ 120
