Solve for the equation, show all your work: This is an absolute value equation so there are possibly 2 answers. Show both equations set up for answers for full credit. |3x - 9| = 12

Step-by-step explanation:

Since this is an absolute value equation we solve for both positive or negative 12

3x-9=12

3x=21

x=7

3x-9=-12

3x=-3

x=-1

So x=(-1,7)

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.
