Mr. Murphy's Megan graph to show his class the amount of water person consumes from food and beverages over time. a person consumes 12 gallon of water each day (i already answerd this part)

(this part is the one im asking about )
complete the equation to show the relationship between X the number of days and Y the amount of water consumed
Y = ? X​

y = 12x

Step-by-step explanation:

From the question, we are told that a person consumes 12 gallons of water each day

Now, we want to complete an equation

From the question, x is the number of days and y is the amount of water consumed

Thus, mathematically, we have the equation as;

y = 12x

since in the first day, 12 gallons is consumed, the second will be 12 * 2 and so on

So the amount of water depends on rate number of days

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
