The equation y = 20 − x/4

gives the number of pounds of dog food y remaining in a bag x days after it is opened. determine whether the relationship between x and y is linear. explain your reasoning.

yes or no the relationship between x and y is linear. the equation can be rewritten as y = − 1/4x+

which is in the form y = mx + b.

This is a linear equation that can be written as: y = -1/4x + 20

Step-by-step explanation:

This is a linear equation because it can be written in the form y = mx + b.

If you take the equation and solve it for 0, 1, 2, 3 days, note the solution:

f(x) = -1/4x + 20

f(0) = 20

f(1) = -1/4(1) + 20 = 19.75 lbs remaining

f(2) = -1/4(2) + 20 = 19.50 lbs remaining

f(3) = -1/4(3) + 20 = 19.25 lbs remaining.

Each day, the amount is less by exactly 1/4 or .25 lbs. This creates a straight line on the graph, which is a linear equation.

Hope this helps :-)

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

answer: there are 453.592 grams in a pound.
