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

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
