Write a equation that shows the equivalency between miles and inches.

X = miles

Y = inches

1 mile = 63360 inches

Therefore 1X = 63360Y

1 X = X

Awnser:

X = 63360Y

Conversions:

1 foot = 12 inches

1 yard = 3 feet = 36 inches

1 mile = 1760 yards = 5280 feet = 63360 inches

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

  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.
