3. Barrett is ordering t-shirts for his school's student council. Company D charges a $30 design fee plus $6.25 per t-shirt. Company E charges a $12 design fee plus
$9.75 per t-shirt. Which inequality can be used to find x, the minimum number of t-
shirts that can be ordered so that the total cost with Company D is less than the total
cost with Company E?

The answer is the second choice,  the rates at which criminals are rehabilitated into society after their sentencing

The first answer is b. then the second one is a

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
