Molly runa 1/2 of a mile i'm 4 minites. If Molly continúes at the same speed, how long will ir take her to run one mile?

8 minutes

Step-by-step explanation:

Molly run 1/2 of a mile in 4 minites.

i.e.,

1/2mile = 4 minutes

then,

multiply each side by 2

1/2 * 2 = 4 * 2

1 = 8

Thus, 8 minutes she will take to run one mile

  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.
