1A Mid Unit Assessment

Which situation matches the table? Circle numbers and box math action words for each situation.

• As part of her marathon training program, Kim ran 20 minutes on her first run and doubled the number of minutes she ran for each of the following four runs.

• Joe received a score of 20% on his first Algebra test. However, he improved and received a score of 100% on his 4th test.

• The company started with 20 employees and added 20 employees each year for four years.

• y = 2x + 3

Write an algebraic rule to describe the relationship in each table.

• y = x + 12

• y = -2x + 9

• y = 4x + 15

Which of the following representations model the pattern shown, if x represents the figure number and y represents the number of blocks in the figure? Select all that apply.

• 
• y = x + 2

• The number of blocks is the figure number plus 3 blocks.

• y = 3x + 1

• The number of blocks is 1 block in the center plus 3 times the figure number.

A sequence is shown in the picture form. Assume that the sequence continues to grow in the same way. What is the algebraic rule for this sequence if C is the total number of circles and N is the row number?

• c(n) = 2n

• c(n) = 2n - 1

• c(n) = n + 2

• n(c) = 2c - 1

• n(c) = c + 2
