Use the discriminant to determine the number of real solutions to the quadratic equation. - 4y^2 – 9y - 3 = 0
What is the number of real solutions?

2 real solutions

Step-by-step explanation:

D = b²-4ac

If D = 0 then 1 real solution

if D > 0 2 real solutions

if D < 0 no real solutions

a = -4

b = -9

c = -3

D = 81 - 48

D = 33

2 real solutions

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
