Please hurry on 22and 23 btw u have to click on the picture to see questions

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

Which set of side lengths form a right side? a) 3ft,6ft,5ft b)50 in,48in,14in c)53m,48m,24m d)8cm,17cm,14cm

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
