Give the values of a, b, and c needed to write the equation's general form. 1/4 x^2 +5 =0

The answer is a = 1/4 , b = 0 and c = 5

Step-by-step explanation:

∵ 1/4 x² + 5 = 0 is a quadratic equation

∵ ax² + bx + c = 0 is the general form of the quadratic equation

∴ a = 1/4

∴ b = 0

∴ c  = 5

For this case we have that, by definition, a quadratic equation is of the form:

In addition, its roots are given by:

If we have the following equation:

So we have to:

there is no term that accompanies x.

Asnwer:

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:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
