Answer:
1. (x,y)→(y,-x)
2. (x,y)→(-y,x)
3. (x,y)→(-x,-y)
Step-by-step explanation:
1. Rotation 90° clockwise (or 270° counterclockwise) about the origin changes x into y and y into -x, so it has the rule
(x,y)→(y,-x)
2. Rotation 90° counterclockwise (or 270° clockwise) about the origin changes x into -y and y into x, so it has the rule
(x,y)→(-y,x)
3. Rotation 180° clockwise about the origin changes x into y and y into -x, so it has the rule
(x,y)→(-x,-y)
Here you can apply rotation by 90° clockwise twice, so
(x,y)→(-y,x)→(-x,-y)
We are given the equation:
cy – 7 = 5d
And we are asked to find for y.
First step, add 7 on both sides:
cy – 7 + 7 = 5d + 7
cy = 5d + 7
Next step, divide both sides by c:
cy / c = (5d + 7) / c
<span>y = (5d + 7) / c</span>
Answer:
I belive that the answer is D because there is 2 items and if u count the different colors by 1 it would be 6
If you want midpoint it would be (2,5)
If you want endpoint it would be (5,8)
Answer:
5
Step-by-step explanation:
17x = 85
17x/17 = 85/17
x = 5
