Which function is the inverse of f(x) = 2x + 3 ? f^-1(x)=-1/2x-3/2
f^-1(x) =1/2x-3/2
f^-1(x) =-2x+ 3
f^-1(x) = 2x+3

At a kentucky friend chicken, a survey showed 2/3 of all people preferred skinless chicken over the regular chicken. if 2,400 people responded to the survey, how many people preferred regular chicken?

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
