Graph the solution of 7x+3<−4 or 2x−3≥9

Step-by-step explanation:

To do this you would simplify both sides.

For the first one:

                     (subtract 3 from both sides)

                      (divide 7 from both sides)

and for the second one:

                       (add 3 to both sides)

                          (divide 2 from both sides)

When you graph these they will look like these pictures    

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
