We know that out of 3000 people, 9 had a alergic reaction.
in this case our 100% is 3000, and we want to know what percentage is equivalent to those 9 that had a mild allergic reaction.
here we can use the rule of 3, this is:
if 3000 is equivalent to 100%, then 9 is equivalent to:
(9/3000)*100% = 0.3%
Answer:
the least value is in the vertex
at the point ( 2/3 , 14/3)
Answer:
x = 48
Step-by-step explanation:
multiply both sides of the equation by 4 to eliminate the fraction
x - 8 = 40 ( add 8 to both sides )
x = 48
I don't know what a radicals is and I can't really show my work cuz I just do it all in my head but I'll solve it for you.
A) (2)(x^2-5x-4) this one can't be simplified anymore unless you use the quadratic formula which I'm too lazy to do
B) (2x-1)(2x-5)
X=1/2 or 5/2
Answer: your answer would be B ^^ (pls mark brainliest)
