Is the solution positive, negative, zero, no solution or infinite solutions?
7x + 14 = 7(x+2)

• infinite solutions
• negative
• no solution
• zero

Is the solution positive, negative, zero, no solution or infinite solutions?
x - 2 = x + 5

• infinite solutions
• negative
• no solution
• zero

For what value of x is it the following equation true?
4(x + 5) = 4x + 5

• 3
• 2
• no solution
• true for any value

Is this mapping a function or not a function? 

• Function
• Not a Function 

Does this relation represent a function?

 

• Yes
• No

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

What is the equation of the line?

• y = -x + 2

• y = x + 2

• y = -x - 2

• y = x - 2

• y = -x + 3
• y = x + 3
• y = -x - 3
• y = x - 3

3 + 12(3p + 2) = 9(p - 3)
