EOC Review #1

The total daily sales at a video store are shown in the expression 21x - 3x², where x is the number of tapes sold.  Which shows this expression completely factored? 

(Hint: GCF)

• 3x(7 - x)

• 3x²(7 - x)

• x(21 - 3x)

• (x - 3)(7 - x)

When the equation y = 3x + 6 is changed to y = -3x + 6, what effect does this change have on the graph? 

• The line moves downward on the y-axis.

• The line slants upward, from the left to right, instead of downward. 

• The line slants downward, from left to right, instead of upward. 

4³⋅4² = ?

• 4⁵
• 4⁶
• 16⁵
• 16⁶

Based on the table below, which statement best describes the data? 

• The data represents a linear function.
• The data does not represent a function. 
• The data represents a quadratic function.
• The data represents an exponential decay function. 

What is the greatest common factor of the expressions 36x⁸y² and 18x⁴y³?

• 2x²y²

• 9x²y
• 18x⁴y²

Which expression is equivalent to x⁶x²?

• x⁴x³
• x⁵x³
• x⁷x³
