Given:
a varies jointly as b and c.
a=6 when b=2 and a=3.
To find:
The variation constant and the equation of variation.
Solution:
a varies jointly as b and c.

...(i)
Where, k is the constant of proportionality.
a=6 when b=2 and a=3.




The value of k is 1.
Putting k=1 in (i), we get


Therefore, the variation constant is 1 and the equation of variation is
.

Answer:
x+ y = 75
Step-by-step explanation:
The both paid a total of 75.
Therefore, in order to get 75 you would need to add the amount each of them paid.
A
Step-by-step explanation:
90 Degree Rotation. When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). ...
180 Degree Rotation. When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). ...
270 Degree Rotation.
