Answer:
y = - 8
Step-by-step explanation:
y - 16 - 3y = 0
Group like terms
y - 3y - 16 = 0
Add similar elements: y - 3y = - 2y
- 2y - 16 = 0
Add 16 to both sides
- 2y - 16 + 16 = 0 + 16
Simplify
- 2y = 16
Divide both sides by - 2
= 
Simplify : y
Apply the fraction rule: 
= 
Divide the numbers: 
= y
Simplify : - 8
Apply the fraction rule:
Divide the numbers: 
= 8
= - 8
y = - 8
The answer is 1.9 gallons
Answer:
Option B is correct
Step-by-step explanation:
We need to find g(h(f(x))
We first find h(f(x))
f(x) = x-3/x
Putting value of f(x) in place of x in h(x)
h(x) = 2x+1
h(f(x)) = 2(x-3/x) + 1
= 2(x-3/x) + 1
= 2x -6 /x +1
= 2x-6 +x/x
= 3x-6/x
Now, putting value of h(f(x)) in g(x)
g(x) = x+3
g(h(f(x)))= (3x-6/x) + 3
= 3x-6/x + 3
= 3x-6+3x/x
= 6x-6/x
So, Option B is correct.
Answer:
The circulation of the given vector is (5/2)x² + 7yz + 6yz + C
Step-by-step explanation:
Given that F = 5xi + 7zj + 6yk
The circulation of F is given as
Integral of F.dr
dr = idx + jdy + kdz
F.dr = (5xi + 7zj + 6yk).(idx + jdy + kdz)
= 5xdx + 7zdy + 6ydz
Integral of F.dr = Integral of (5xdx + 7zdy + 6ydz)
= (5/2)x² + 7yz + 6yz + C
