CCSS.8.F.A.1

Identify the domain of the following relation:

• {-6, 14, 2, 28}

• {-6,14, 0, 32, 2, 38, 4,44}

• {-6, 0, 2, 4}

• {14, 32, 38, 44}

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.

An Algebra book has a total of 1382 pages which is broken into two parts. The second part of the book has 64 more pages than the first part. Write a system of equations to find the number of pages for each part of the book. Let  x =  number of pages of the first part of the book and y = number of pages of the second part of the book

• x + y =1382
  y = 64x

• x + y =1382
  y = 64 + x

• x + y =1382
  y = x - 64

• x + y =1382
  y = -64x

Write an equation that could be used to find how many packs of DVDs you can buy with 168 dollars if one pack costs 12 dollars.

• 168x = 12

• 12x = 168

• 12(168) = x

• 12 / x = 168
