What is the value of the discriminant of the quadratic equation -2x =-8x+8, and what does its value mean about the number
of real number solutions the equation has?

For this case we have the following quadratic equation:

This is equivalent to:

Where:

The discriminant is given by:

Substituting the values we have:

The discriminant is zero, so the equation has two equal real roots.

The equation has two equal real roots.

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
