9. think of another quadratic equation that has one (1) real number solution. write the equation in ax2 bx c 0 form. then find the value of the discriminant to support your answer.
10. think of another quadratic equation that has no (0) real number solutions. write the equation in ax2 bx c 0 form. then find the value of the discriminant to support your answer.
need solutions on each equation, . solutions to previous examples look like this:   a=1    b=4        c=4          b²-4ac        =2²-4(3)(1)  =4-12      =-8 you!

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.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
