f(x) = -2x
-2x = 0
x = 0/-2
x = 0
Now putting 0 as x in g(x)
g(x) = 8x^2 - 5x + 7
g(0) = 8(0)^2-5(0)+7
= 0 - 0 + 7
= 7

Normalize 
by dividing by its magnitude:
Multiply by -1 to reverse its direction, and again by 
to ensure this new vector has the magnitude we want. Notice that 
.
Answer:
If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.

Answer:
9/16 gallons
Step-by-step explanation:
We can use a ratio to solve
3 /16 gallon x gallons
------------------ = --------------
1/3 ft^2 1 ft^2
Using cross products
3/16 * 1 = 1/3 x
Multiply each side by 3
3/16 * 3 = 1/3x *3
9/16 = x
9/16 gallons
