Answer:
the given equation is y=4/7x
reciprocating both sides you get y/x =7/4
now x and y are directly porportional to each other so
x=ky where k is the constant
or x/y=k ......................(2)
equating 1 and 2
k=7/4
Step-by-step explanation:
d(n)=8−6(n−1)
d(6) = 8-6(d-1)
d(6) = 8-6*5
d(6) = 8-30
d(6) = -22
n-p for the first, p-n for the second
1/5
formula is y = kx
k is the constant of proportionality
when x is 5 y is 1
when x is 10 y is 2
so 1 = k * 5
so k = 1/5
12x+18
That is allready completely simplified.
