Answer:
y=-2x
Step-by-step explanation:
(3n-2) x (4n+1) =0
All you need to do is to find what value of n makes each factor equal 0.
First Term:
3n-2 = 0
3n = 2
n = 2/3
Second Term:
4n+1 = 0
4n = -1
n = -1/4
n ={2/3, -1/4}
Answer: 33 gallons
Step-by-step explanation:
We initially have 130 gallons of a 
acid solution and we need to change it to a 
acid solution, and for that it is necessary to evaporate 
gallons of water.
So, this situation can be mathemtically expressed as follows:
Then:
Isolating :
Hence, we need to evaporate 33 gallons of water.
Answer:
C and E
Step-by-step explanation:
Recall that according to the complex conjugate theorem, if P(x) is a polynomial function with real coefficients, and a+bi is an imaginary root of P(x), then its conjugate (i.e a-bi) must also be a root.
Here we see that 2 of the given roots are imaginary : i and 2+i
by the theorem given above, the conjugates of these must also be roots
i.e -i and 2-i
The answer is B my friend
