Answer:
The correct option is A) Down.
Step-by-step explanation:
A function can be shift vertically up or down by adding some positive or negative constant.
For example:
Consider the figure 1:
The function 
shifted up by <em>k</em> unit. (where <em>k</em> is 1 unit)
Now consider the figure 2:
The function 
shifted down by <em>k</em> unit. (where <em>k</em> is 1 unit)
Which means to shift the graph of an equation certain number of units up, we need to add that number from the functions equation.
Similarly, to shift the graph of an equation certain number of units down, we need to subtract that number from the functions equation.
Therefore, the correct option is A) Down.
Given:
4 relations in the options.
To find:
The relation which represents a function.
Solution:
We know that, a relation is a function if there exist a unique output value for each input value.
In option A, we have two output values y=-5 and y=1 for single input value x=-1. So, it is not a function.
In option B, we have two output values y=2 and y=4 for single input value x=3. So, it is not a function.
In option C, we have two output values y=1 and y=7 for single input value x=-1. So, it is not a function.
In option D, we have unique output value for each input value. So, it is a function.
Therefore, the correct option is D.
375 mi^2 15
--------------- = ------ = 3/2
250 mi^2 10
The ratio of the population of Henderson County to that of Perquimans is 3/2.
The answer would be 1/6 assuming a fair trial
Answer:
1.89
Solution:
We have -44x - 86 = -3
First, we move the non x terms to the RHS of the equation. To do this, we add 86 to both sides.
Note: if a = b, then a + c = b + c
Therefore, -44x - 86 + 86 = -3 + 86
or, -44x = 83
Next, divide both sides by -44, which is the coefficent of x
Note: if a = b, then a ÷ c = b ÷ c
-44x
-44
=
83
-44
or, x = -1.89
