56x7y5, if x+0 and y#.0? Which expression is equivalent to V
OA. 2x2y7xy2
OB. 8x4/7x472
Oc. 8 x 27 Try2
OD. 2244 297

A is the answer.

Step-by-step explanation:

We have

Factor the radical by taking perfect squares of the real numbers and the exponents.

56 can be made up of perfect 8, x^7 can be made up of x^6 and y^5 can be made up of y^3. So we get

Take the cube root of 8x^6y^3.

Which is 2x^2y.

A is the answer.

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.
