If x+12 is a factor of a polynomial, what would it tell you about the polynomial ​

That is has root -12 meaning if you replace x with -12 you get 0.

Let p(x) = polynomial function.

Let g(x) = a factor of p(x).

g(x) = x + 12

Let g(x) be 0.

0 = x + 12

-12 = x

The binomial x + 12 tells us that -12 is the solution of p(x).

In other words, g(x) is a factor of p(x) because when x is -12, p(x) becomes 0.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
