Question

if y varies directly as 2p+3.and y=14 when p=2,find y when p=5......(direct variation)

can somebody help me please.....i really2 need ur help.....please.....

Answer 1

y = 2 (2p+3)
put p=5

Answer 2

y=14 when p=2
putting the value of p in this expression:
2p+3, we get
2*2+3 = 7
when the whole expression is 7 (i.e. 2p+3) y=14 which is exactly the double of the value of expression

2*expression = y
this is the relation
now when p=5

(2*5)+3=13,
so y=26, double the expression

Hope that makes sense
