Answer:
Therefore the constant of proportional is r=7.
Step-by-step explanation:
The quantities x and y are proportional.
   x         y
i) Â Â 2 Â Â Â Â Â Â Â 14
ii) Â Â 6 Â Â Â Â Â Â Â 42
iii) Â 11 Â Â Â Â Â Â Â 77
Since x and y are proportional.
y= rx
(i)
Now plug y= 14 and x=2
14=r.2
[tex]\Rightarrow r=\frac{14}{2}[/tex]
[tex]\Rightarrow r=7[/tex]
(ii)
Now plug y= 42 and x=6
42=r.6
[tex]\Rightarrow r=\frac{42}{6}[/tex]
[tex]\Rightarrow r=7[/tex]
(iii)
Now plug y=11 and x=77
77=r.11
[tex]\Rightarrow r=\frac{77}{11}[/tex]
[tex]\Rightarrow r=7[/tex] Â Â
Therefore the constant of proportional is r=7.
