1 gallon =128
1/2 gallon =64
128 x 5 (gallons)= 640 + 64 (1/2 gallon)= 704
so your answer is 704
Answer:
i need more info
Step-by-step explanation:i dont understand what suppose to do bro
The general solution of the given higher-order differential equation. y''' − 9y'' 15y' 25y = 0 is Y= c1e^-x +c2e^5x + c3xe^5x
m^3 -9m^2+15m+25=0
Possible rational roots = 1,-1,5,-5,25
Now on putting these possible rational roots which have been found by the discriminant and hit and trial method,
we will check these roots.
m=-1 comes out to be a root of the equation.
m^2-10m+25=0
(m-5)(m+5)=0
(m-5)^2=0
m=5
So the general equation comes out to be
Y= c1e^-x +c2e^5x + c3xe^5x

Answer:
C. 3x - y = -2
Step-by-step explanation:
We know that lines with the same slope are usually parallel
3x - y = -2
-y = -3x - 2
y = 3x + 2
They have the same slope so we can assume that they're parallel
You can also graph to check this
