Answer:
C, 150 in
Step-by-step explanation:
12 in x 25 = 300
300/2
=150 in
Subtract 5 and 3 then add 3 to the number you get? Idk I think thats what you do
we know that in direct variation as x increase y also increases.
in indirect variation x decreases y increase and vice versa.
in part a we have x at top (numerator ) and y at denominator it mean indirect variation (as x increases y decreases).
to find k we know that for indirect variation xy=k
if we rewrite the equation x=9/y we get xy=9
which mean k=9 .
in part b we have 4xy=20 if we simplify this equation we get

so here if we rewrite in terms of x.
we get x=5/y which represents indirect variation.
and we know xy=k
we have xy=5 .so k=5
Answer:
y = 1x - 5
Step-by-step explanation:
= 30%
= 0.3
= 3/10
Hope this helps.
