Solve x2 – 8x + 41 = 0 for x.

x=-4 (-+)square root of 37i
x = –4 ± 5i

x=4(-+) square root of 37i
x = 4 ± 5i

The equation is quadratic equation that requires finding discriminant

Since discriminant is negative, this equation has two complex roots. Note that where is imaginary unit. Then

Now the complex roots are

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.
