Find the values of c and d that would make the following equation true

c = 2, d = 3

Step-by-step explanation:

multiply factors on left side gives

9 c = 18 ( divide both sides by 9 )

c = 2

For both sides to be equal then

c = 2 and 3 + d = 6 ⇒ d = 3

As a check

left side = 2 × 9 = 18 = right side

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.
