Answer:

You would need $18 total to buy the racks needed.

Step-by-step explanation:

First, every 20 CDs needs a new rack, so you would divide 120 by 20.

120 / 20 = 6 racks

Second, you would multiply the price ($3) of a rack by how many racks needed.

3 * 6 = $18

Use algebra to find the point at which the line f(x)=-5/3x+4/3 intersects the line h(x)=1/5x+4/3
Sedaia [141]

Answer:

The point x=0 y=4/3 I.e (0,4/3)

Step-by-step explanation:

To find interpoint we use this knowledge

For the same value of x, functions f(x) and g(x) have the same value. So we need to find x. We will find it ftom this equation:

f(x)=h(x) i.e.

-5/3x+4/3=1/5x+4/3

-5/3x-1/5x=4/3-4/3

-28/15x=0

So we can conclude that x=0

So f(0)=h(0)=4/3
