75% of medicine this person took, you do that by doing 420/560 and you get .75. Then you move the decimal over twice since it asks for a percent and you get 75%
Answer:
It's B
Step-by-step explanation:
Just divide y by x. For example: 6.6 / 6 = 1.1. This would be B! Hope this helps!
6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots
