use the discriminant to describe the roots of each equation. then select the best description.

2x^2 + 7x + 6 = 0

x^2 - 5x - 4 = 0

6x^2 + 13x + 6 = 0

16x^2 + 8x + 1 = 0

2x^2 + 7x + 6 = 0

2m^2 + 3 = m

2 = x^2 + 5x

x^2 + 9x + 14 = 0

the options are:

double root
real and rational roots
real and irrational roots
non-real roots

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
