We are given coordinates of the triangle: A(2,2), B(7,1) and C(8,-4).
We need to rotated 90° counterclockwise about the origin.
In order to find the new coordinates of rotatation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).
Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.
In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.
On applying rule (h, k) ---> (-k,h), we get
A(2,2) --> A'(-2,2)
B(7,1) --> B'(-1,7)
C(8,-4) --> C'(4,8)
Answer:
Let x = the number. Then you have:
2x + 14x = 48 Collect like terms
16x = 48 Divide both sides by 16
x = 3

Answer:
5a=3b
Step-by-step explanation:
5a+3b=6b
5a=6b-3b
5a=3b
Assuming the diameter is one, it should be (pi)/2 or 1.57 units.
Answer:
x = 8
Step-by-step explanation:
Step 1: Write equation
2(x + 5) = 26
Step 2: Solve for <em>x</em>
<u>Distribute 2:</u> 2x + 10 = 26
<u>Subtract 10 on both sides:</u> 2x = 16
<u>Divide both sides by 2:</u> x = 8
