7. after a blizzard the amount of snow on the ground melted by 3 inches one day and then another
8 inches the next day. write an expression that represents the total change in the amount of snow
on the ground over the two days.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
