Answer:
Yes, "y" varies directly with "x".
The equation is: 
Step-by-step explanation:
By definition, Direct variation equations have the following form:
Where "k" is the Constant of variation.
If you solve for "k", the equation is:
Then, given the table provided in the exercise, you can know if "y" varies directly with "x" by finding the quotient of the correspoding values of "x" and "y":
- Dividing 
by 
you get:
- Divide 
by 
:
- Dividing 
by 
:
Since the quotient is constant, then "y" varies directly with "x" and the the Constant of variation is:
Therefore, the equation for the Direct variation is:
Answer:
A
Step-by-step explanation:
notice that the graph has a vertical asymptote.
to find a VA, you set the denominator = 0.
since the VA is at x = 5, choice A is the only one with a denominator that = 0 when 5 is plugged in
Answer:
$3600
Step-by-step explanation:
Cost of the car = $8000
The car loses value at 11% each year .
That’s
11% /100% x $8000
0.11 x 8000
$880
11% decrease each year means that the cost of the car is reduced by $880 per year.
Therefore,
Worth of the car in 5 years
= $8000 - ($880 x 5)
= $8000 - $4400
= $3600
The car will be worth $3600 in five years
In mathematical modeling<span>, </span>statistical modeling<span> and </span>experimental sciences<span>, the values of </span>dependent variables<span> depend on the values of </span>independent variables<span>. The dependent variables represent the output or outcome whose variation is being studied. The independent variables represent inputs or causes, i.e., potential reasons for variation or, in the experimental setting, the variable controlled by the experimenter. Models and experiments test or determine the effects that the independent variables have on the dependent variables. Sometimes, independent variables may be included for other reasons, such as for their potential </span>confounding<span> effect, without a wish to test their effect directly.</span>
