PLEASE HELP! I need to get this right to boost my grade, and I'm having trouble understanding it but there's a deadline to turn it in. Could anyone help me? Estimate the area of the irregular shape (don’t forget to show work). Explain your method.

I included a picture, I hope it helps.

Plz i beg u asap ! what is the equation of this graphed line? enter your answer in slope-intercept form in the box.

Abag contains 4 red, 7 blue and 5 yellow marbles. event a is defined as drawing a yellow marble on the first draw and event b is defined as drawing a blue marble on the second draw. if two marbles are drawn from the bag, one after the other and not replaced, what is p(b|a) expressed in simplest form? a. 7/16 b. 7/15 c. 14/16 d. 14/15

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 2
