Answer:

B

Step-by-step explanation:

Easiest way is to use process of elimination by plugging in x numbers from the table in the equation to find the y and see which one matches.

Plug in 10 for x and y should be -1

Check A:

y= 2/3(10)-8\\y=-1.33

Not A, doesn't equal -1

Check B:

y = 3/2(10)-16\\y=15-16\\y=-1

Correct, might be B

Check another point (20,14):

y=3/2(20) - 16\\y=30-16\\y=14

Correct, it is B.

You can check other 2 and see that they are wrong.

B = 1/2 bh  where b is 8 and h is 5

  = 1/2 (8) * 5

  =20

V = 1/3 (20) 10

 66.6666666

To the nearest tenth
