  1. rearrange the equations to ...

    y>-3 and
    x>1 and
    y<3

    This means that y is between -3 and 3, x>1

    Does that help?

  3. Sorry, I can not graph this for you.
    However
    3 - y < 6
    Multiply both sides by -1, when you multiply inequality by negative quantity, change direction of arrow
    -3 + y > -6
    or
    y > -3
    So everything above the horizontal line y = -3 is in so far.
    x>1 so everything above -3 and right of x = 1 is in so far
    y <3 so everything between y = -3 and y = +3 and right of vertical line x=1 is in

  4. Mary, use - 1 for x

    Since you did not type an equal sign I assume you mean
    If f (x) = 4x - 3, find the following f (-1)

    f(-1) = 4 *(-1) - 3

    = -4 -3

    = -7

    solve system graphically. be sure to check your solution. if a system has infinite number of solutions, use set builder notation to write the solution det. if a system as no solution, state this. a=1+b b=5-2a
