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:
A
Step-by-step explanation:
x+y=34 (add the seperate hours together to get the total amount of hours)
10x+15y=410 (multiply the money made each hour by the hours worked and add them together to get the amount of money joy made)

Answer: £164.50 i think soooo
So you will use slope formula which is m = (y2 -- y1) / (x2 -- x1)
-1 minus -7=6
13 minus -8=21
Remember it changes to a positive Keep,Change,Change
So its 6/21
Or 1/4
