first, love the killua profile picture ! i love hunterxhunter i am currently on season 5, episode 44 or 45 aka 119 or 120 but anyways,
answer:
b = 2
step-by-step explanation:
because its roots are -4 and 2,
and a = 1 [The coefficient of 
] we know that 
using the distributive property we get,
by equating coefficients (common strategy for partial fractions and undetermined coefficient method of solving ODE), we get b = 2 and c = -8 ( solved c just for fun guess :) ) .
hope this helps :)

Answer:
Step-by-step explanation:
I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A
: It looks like this in the calculator
× cos A=
(0.6489)
(
and cos cancels out)
A=
(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
Answer:
C
Step-by-step explanation:
So this is transformations
So this seems like it was rotated 180 degrees then dilated by a scale factor
The rule for 180 degrees is (-x,-y)
The rule for dilations is (2x,2y)
So the answer should be
C. (-2x,-2y)
Have a nice day
Answer:
Kevin must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime.
Step-by-step explanation:
Given : Kevin wants to make a mixture that is 50% lemon juice and 50% lime juice. 100% lesson juice should he add to a juice mixture that is 40% lemon juice and 60% lime juice to make 6 gallons of the 50% lemon 50% lime juice mixture.
To find : How much 100% lesson juice should he add to a juice mixture.
Solution :
According to question, we wants to make mixture where lemon = lime
We have to make 6 gallons, where
40% lemon juice require to make 6 gallon
i.e, 
and 60% lime juice require to make 6 gallon
i.e, 
Now, to make them equal subtract both of them
Therefore, he must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime.
