If we are going to analyze the problem very well, the equation that we will be able to make would be: 2x + 6y = 72
72 is the oz of water conditioner to use in his fish tanks.
small tanks would require 2 oz of conditioner
large tanks would require 6 oz of conditioner
There is only one point which satisfy's the above equation.That is the points of (0, 12) and (36, 0)
The answer is 1.80 because
0.25 times 3.00 is 0.75
minus 0.75 to 3.00 and it will be 2.25
0.20 times 2.25 will be 0.45
minus 0.45 to 2.25
and u will get 1.80
Answer:
the answer is 600

Answer:
8 gallons
Step-by-step explanation:
3x4=12 (do the same to the opposite) 2x4=8 or 8 gallons of blue paint (to be more specific)
Answer:
a.
b.
Step-by-step explanation:
We have a differential equation
y''-2 y'-35 y=0
Auxillary equation
By factorization method we are finding the solution
Substitute each factor equal to zero
D-7=0 and D+5=0
D=7 and D=-5
Therefore ,
General solution is
Let
We have to find Wronskian
Substitute values then we get
a.
We are given that y(0)=-7 and y'(0)=23
Substitute the value in general solution the we get
....(equation I)
......(equation II)
Equation I is multiply by 5 then we subtract equation II from equation I
Using elimination method we eliminate
Then we get
Substitute the value of in I equation then we get
Hence, the general solution is
b.
