Factor the trinomial below . x^2-2x-48

Step-by-step explanation:

We have been given a trinomial . We are asked to factor the given trinomial.

We will use split the middle term method to factor the given trinomial. We need two numbers, whose sum is -2 and product is -48. We know two such number are .

Split the middle term:

Make two groups:

Factor greatest common factor of each group:

Use distributive property  backwards:

Therefore, factorized form of the given trinomial would be .

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.
