If AC = 3y - 5 and HJ = 4y + 2, what is HB?

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

Average acceleration: i have no idea how to do this.

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
