What is the value of the discriminant of the quadratic equation -1 = 582-2x, and what does its value mean about the number of real number solutions the equation has?
O The discriminant is equal to -16, which means the equation has no real number solutions.
The discriminant is equal to -16, which means the equation has two real number solutions.
O The discriminant is equal to 24, which means the equation has no real number solutions.
O The discriminant is equal to 24, which means the equation has two real number solutions.

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.

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

answer:

125 yards

explanation:

75+50=125. that is my answer

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
