Which expression is equivalent to 3(m − 3) + 4? 3m + 1 3m − 5 3m + 13 3m − 3

3m − 5

Explanation:

In order to find the equivalent of the expression, we just need to solve the expression by using the distribute property, which tells that a product in the form

is equivalent to

So, let's apply this property. Let's rewrite the original expression first:

Now we apply the distributive property to the parentheses:

By adding the last two terms,

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.
