• 4

• 3

• 7

• 10

In the ordered pair (4,9) which number is the Y COORDINATE?

• 4

• 9

• neither

• both

What is the algebraic expression for "Twice x, decreased by 9?"

• 9 - 2x

• 2 + x - 9

• 2x - 9

• 2x / 9

Simplify this expression (combine like terms):
6y + 5y + y - 2

• 10y

• 11y + y - 2

• 12y - 2

• 13y

Simplify this expression (combine like terms):
6a + 1 - 2a

• 4a + 1

• 7a - 2a

• 8a + 1

• 6a + a

Solve:
3(x - 2) = 18

• 6.7

• 4

• 8

• -4

Solve:
7x + 19 = -2x + 55

• 4

• 14.8

• 8.2

• -4

Solve:
2(2x + 3) = -6(x + 9)

• 2

• 6

• -6

• 7.5

Solve the proportion.

• q=2

• q=9

• q=4.5

• q=6

what does this equation help you find?
