A sporting goods store sells left handed (x) and right handed (y) gloves. In one month, 12 gloves were sold for a total of $561. Right handed gloves cost $45 each and left handed gloves cost $52. Which system could be solved to determine the number of each type of glove sold?

• x + y = 561

  45x+52y=12

• x + y = 12

  52x+45y=561

• x + y = 12

  45x+52y=561

• x + y = 561

  52x+45y=12

Does this graph have a maximum or minimum?

• Minimum

• Maximum

Determine if the equation shown has one solution, no solution, or infinitely many solutions.

• One Solution

• No Solution

• Infinitely Many Solutions

Convert to the following equation to slope-intercept form:

5x + 3y = 12

• 3y = -5x + 12

• 5x = -3y + 12

• y = -5/3x + 4

• x = -3/5y + 12/5

Graph the solution to the system. The first equation has been plotted for you.

y = -3x-3

y= 4x +4

What is the value of y in the solution to this system of equations? 3x - 5y = 22 y = -5x + 32
