What is the equation in slope intercept form of the line that passes through (5, -1) and is parallel to y = -3/5x - 4.

• y = 3/5x - 4

• y = -3/5x + 1

• y = 5/3x - 28/3

• y = -3/5x + 2

I bought $3 each for tacos and $1.50 each for sodas and spent a total of $15. I purchased a total of 6 items. Which systems of equations can be used to find the total number of tacos and sodas that were purchased?

• x - y = 6

  3x - 1.5y = 21

• x + y = 15

  1.5x + 3y = 6

• 3x + 1.5y = 15

  x + y = 6

• x + y = 15

  x + y = 6

• Domain:  $0\ge x\ge-14$  
  Range:  $g\left(x\right)\ \ge-2$  

• Domain:  All real numbers
  Range:  $0\le y\le-2$  

• Domain:  All real numbers
  Range:  All real numbers

Which function is equivalent to f(x) = $4x^2+16x+15$ 

• f(x) = (x + 15) (x + 1)

• f(x) = (2x + 15) (2x +1)

• f(x) = (4x + 5) (x +3)

• f(x) = (2x+3) (2x+5)
