Identify the like terms of 3x, choose all that apply:

3y
5x
3xy
-2x
3
7y
x

5x, -2x, x brainliest?

Step-by-step explanation:

5x, -2x and x.

Step-by-step explanation:

Like terms are those that contain the same variables and with the same exponents, regardless of the coefficient or the sign they may have.

In this case we have the term 3x, the variable is x, so like terms must be those that contain x.

let's analyze the options:

In summary, like terms of 3x are: 5x, -2x and x.

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.
