34) apply the distributive property to simplify the expression. 5(3x − 7) a) 15x + 35 b) 15x − 35 c) −15x + 35 d) −15x − 35

B.

Step-by-step explanation:

We are asked to simplify the expression using distributive property.

Distributive property states that we can multiply a quantity to sum by multiplying each addend separately and then add the products as:

Using distributive property, we will multiply 5 by and as:

Therefore, the simplified form of the given expression would be and option B is the correct choice.

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.
