Alexandra holds a drawing on a transparency paper LaTeX: \overline{XW}X W ¯ in front of a flashlight held at point V. Her drawing is projected on the ceiling at LaTeX: \overline{ZY}Z Y ¯ such that LaTeX: \overline{ZY}\:\parallel\:\overline {XW}.Z Y ¯ ∥ X W ¯ . The length of LaTeX: \overline{XW}X W ¯ is 12 inches. What is the length of the drawing projected on the ceiling?

y=1/4x-4

step-by-step explanation:

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.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

i think its a and d
