Question

Peaches are being sold for $2 per pound. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y? The values of both x and y can be any real number. The values of both x and y will be real numbers greater than or equal to 0. The value of x can be any real number, but the value of y will always be a real number greater than or equal to 0. The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

Answer 1

Given:
Peaches = $2 per pound
x = number of pounds
y = total cost of the peaches.

y = 2x  

This is a direct variation equation. Where y varies directly with the value of x.

The values of both x and y will be real numbers greater than or equal to 0.

x            y = 2x
0            0
1            2 
2            4
3            6 
4            8
5           10

Answer 2

Answer:

The values of both x and y can be real numbers greater than or equal to 0.

Step-by-step explanation:

There is a direct relationship between x and y, that is why the values of x and y can not be any real numbers. The value of y is dependent on the value of x, so, if x is 0 then y is 0. And if x is greater than 0, y also would be greater than 0.
