15 Points! URGENT The blue line is the graph of y = –x + 3. Use the sliders to make the orange line represent y = –2x + 9. Examine the graph. What appears to be the solution of this system of equations?

Verify the solution. Which true statement appears in your check?

Which system of linear inequalities is represented by the graph?

Will mark ! (10 points also! ) if x varies inversely with y and x =6 when y= 10, find y when x=8 a. y=4.8 b. y=7.5 c. y=40/3 d. y=4/15

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.
