First, distribute the left side. You should get 4x-8-2x+4=4x-8. Then, get all the xs on one side.
4x-2x-4x-8+4=-8
Then, put the numbers on one side.
4x-2x-4x=-8+8-4
Then, add it up.
-2x=-4
Then, solve for x.
(-2x)/(-2)=(-4)/(-2)
x=2
Hope that helps!
Answer:
3n
Step-by-step explanation:
the output is 3 times the input
three times n equals 3n
Domain is the numbers you can use
range is the result of inputing the domain
an interesting fact is that the inverse of a function switches the domain and range
basically
the domain of f(x) becomes the range of f^-1(x)
the range of f(x) becomes the domain of f^-1(x)
so just find the domain and range of f(x)

there are no restrictions
all real numbers can be used
all real numbers can result
so the answer is domain and range for both is all real numbers

Answer:
1 mile is mapped to 0.3428 inches i.e. unit rate is 0.3428 inches/mile.
Step-by-step explanation:
Given that the scale of the map is
inches =
miles ....... (1)
Now, we have to convert this map scale to a unit rate.
And the unit rate is the number of inches per mile.
As the scale is constant, therefore from the the relation (1) we get
1 mile =
inches.
Therefore, 1 mile is mapped to 0.3428 inches i.e. unit rate is 0.3428 inches/mile. (Answer)
