Mark used a number line to model diving 2/3 by 3. He divided the number line from 0 to 1 in 3 equal sections , and then divided each of those sections into 2 equal parts. Mark says 2/3 divided in to 3 is 1/3

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
