(4.8 x 10?) - (3 x 105)
what is the scientific notation?

-2.67 x 10^2

Step-by-step explanation:

Move the decimal to the left of the decimal point . The decimal places you will move will be the exponent 10. If the decimal is being moved to the right that means the exponent will be negative. if the decimal is moving to the left, the exponent would be positive.

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.
