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 :-)

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
