C = r + rvf
Subtract r from each side:
C-r = rvf
Divide both sides by rf:
V = (c-r)/rf
Answer:
18
Step-by-step explanation:
You have 25 when you are done, but you made 7, so subtract that from 27.
25-7 equals 18.
Answer:
Object point Q (x,y) ------------- image point Q'( -y,x)
Step-by-step explanation:
When a point A (x,y) is rotated 90 degrees counterclockwise about the origin the resulting image of the point is A'(-y,x)
This means first you alternate the positions of x and y coordinates then add a negative sign on the now new y coordinate.
Example a point B(2,3) rotated 90° counterclockwise about the origin will form an image B'(-3,2)
So if point Q (x,y) ------------- image Q'( -y,x)
Substitute real values for (x,y) coordinates to get correct answer.
2/5ths divides by 3 and 1/10 is 0.129
