CPM Algebra Chapter 2

Write an algebraic expression for the picture given.

Which side is greater?

• Left side

• Right side

• Both sides are equal.

• It depends on the value of x.

There are 23 Algebra books for every 9 Geometry books in the math book room. If there are a total of 207 Algebra books, then how many Geometry books are there in the book room?

• 81

• 1

• 136

• 529

Which expression describes this pattern?

• 2n + 3

• 3n + 2

• n + 3

• 3n - 2

• 3n

Is the graph a function? Why?

• Yes. Each input has exactly one output.

• No. The graph does not go on forever.

• No. The graph does not have a pattern.

Which side is greater?

• Left side

• Right side

• Both sides are equal.

• It depends on the value of x.

Solve. 2x - 4 = -7x + 14

• x = -2

• x = 2

• x = 1/2

• x = -1/2

Solve for y. 3y - (5y + 2) = -2y + 6

• y = 0

• y = -2

• y = 2

• No solution

• All numbers

Solve. 3a - (4a - 7) = 4a - 3 - 9a - 6

• a = 4

• a = -4

• a = -8/3

• a = -1/2

Solve for y. Just put the answer.

Don't put y =!
