Algebra Part 1

Write the expression: two times a number decreased by five

• 2x - 5

• 5- 2x

• 2 x x - 5

• 2 * 5 - x

Which is the rule for the function table below

• y = x - 3

• 3x = y

• y = 3 + x

• x + 3 = y

Is the ordered pair (5,4) a solution to the equation 6 - x = y

• Yes

• No

When x increases by 2, what happens to y in the equation 2x + 3 = y

• y increases by 2

• y decreases by 4

• y decreases by 2

• y increases by 4

Complete the table below and write the equation for the line.

• 6; y = x + 6

• 5; y = x - 4

• 4; y = x - 4

• 13; y = x + 4

What is the equation for the line on the graph?

• y = x + 1

• y = x - 3

• y = 2x - 1

• y = 2x + 1

The Big Red Mobile Company charges Sue $.15 for each text and a monthly fee of $30. Which equation matches the statement.

• .15 + 30t = c

• c = 30 + .15

• .15t + 30 = c

• c = .15 + 30t

Evaluate the expression with the given values. Show all steps 4( x² + b)

x = 3 and b = 4

Which is the rule for the table above.

• 2x + 4 = y

• 3x + 2 = y

• x - 2 = y

• 3x - 2 = y

Write an equation for the following: The card store is selling cards for $4.50 each. You also have a coupon for $2.00 off.

• 2.00c - 4.50 = t

• 2.00 - 4.50t = c

• 450c - 200 = t

• 4.50c - 2.00 = t
