The area of a triangle A is 15 square units. The area of triangle B is 60 square units. A) What scale factor was used to get from triangle A to triangle B? Scale Factor = b) Using the same triangle A that has an area of 15 square units as the original, what would be the area be of a scaled copy that was drawn using a scale factor of 5? Area = square units

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.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
