Simplify the expression\(\frac{2x^{-1}y}{x^3z}\) for \(x=2\), \(y=8\), and \(z=-1\).

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

… = -1

Step-by-step explanation:

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

… = -1  

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.
