Susan and bethany are training for a half marathon. susan trains at a rate of 3 miles every half hour, and bethany trains at a rate of 5 miles every 45 minutes. what is the unit rate, in miles per hour for each runner? who trains at a faster rate

Bethany

Step-by-step explanation:

Susan - 6 miles per hour

Bethany - 60/45 = 4/3

4/3 x 5 = 20/3 = 6.666

  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.

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
