3. at a poster shop, han paid $16.80 for 2 large posters and 3 small posters of his
favorite band. kiran paid $14.15 for 1 large poster and 4 small posters of his fa
tv shows. posters of the same size have the same price.
find the price of a large poster, l, and the price of a small poster, s.

small posters cost $2.30 each

large posters cost $4.95 each

Step-by-step explanation:

Let

price of large poster be "l", and

price of small poster be "s"

$16.80 for 2 large and 3 small, we can write:

2l + 3s = 16.80

Then,

$14.15 for 1 large and 4 small, we can write:

l + 4s = 14.15

We can write this as:

l = 14.15 - 4s

Now we substitute this expression for "l" into first equation and solve for s first:

small posters cost $2.30 each

Now, we know l = 14.15 - 4s, so

l = 14.15 -4(2.30)

l = 4.95

large posters cost $4.95 each

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
