The answer to your question is below

Step-by-step explanation:

1.What is the algebraic expression for the following word phrase: the sum of 3 and 4x?  3 + 4x

2. What is the algebraic expression for the following word phrase: the quotient of 8 and the difference of x and y?

3. What is the algebraic expression for the following word phrase: the quotient of x and 2y?  

4. Which word phrase can you use to represent the algebraic expression 4m? Four times a number.

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.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
