Simplify the algebraic expression -2(x - 3) + 4(-2 x + 8)
*Plz explain your answer*

-10x+38

Let's simplify step-by-step.

- 2(x – 3) +40-2r + 8)

Distribute:

= (-2)(x) + (-2)(-3) + (4)(-2x) + (4)(8)

= -2x + 6+ - 8x + 32

Combine Like Terms:

= -2x + 6 + - 8x + 32

= (-2x + - 8x) + (6 + 32)

-10x + 38

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.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
