United fabrics international, inc., bought a fabric design from an italian designer and registered a copyright for it with the u.s. copyright office. when macy's, inc., began selling garments with a similar design, united filed a copyright infringement suit against macy's. macy's argued that united did not own a valid copyright to the design and so could not claim infringement. does united have to prove that the copyright is valid to establish infringement?

United must prove that copyright is valid to establish infringements.

Explanation:

Copyrights are norms established by law to protect the relationship between the creator and the use of his creations, be they artistic, literary or scientific creations, such as texts, books, paintings, music, illustrations, photographs, etc. With the use of copyright the creator of something can prevent the use of its creation as long as it proves that it is the copyright holder of that creation. Based on this, we can conclude that United must prove that copyright is valid to establish infringements.

Explanation:

Given the equation that models Damon's saving plan as y = 500 + 400x  where x represents the number of  months since last week and y represents the total amount he's saved for the vacation. Since he estimates that he'll need about $2,500 for the trip, therefore y = $2,500.

In order to determine how many more months of saving (x) it will take to reach his goal, the following steps must be taken by Damon (Damon true statements)

Step 1:

y = 500 + 400x

Step 2: Subtract 500 from both sides

y - 500 = 500 + 400x - 500

y-500 = 400x

Step 3: Substitute y = $2500 into the resulting equation and solve for x

400x  = 2500-500

Step 4:  Take the difference of the value at the right hand side of the equation

400x = 2000

Step 5: Divide both sides by the coefficient of x (i.e 400)

Step 6: Get the value of x

x = 5
