A function behaving as you state is a linear function, which means that the output varies directly with the input.
So, there exists some constant 
such that your function is in the form
In fact, if you double the input, you have
And similarly
Note that this is a guess, it may happen that output doubles (triples) if you double (triple) the input, and still the function is not like 
.
For example, the function
is such that
So, it may seems that doubling and tripling the input doubles and triples the output, but this is not true for every input, for example,
And so doubling the input didn't double the output.
The correct answer is 1.5,1.2
the x value should be positive because it's under the sqrt.
the y value is also positive from the first equation.
Answer:
true
Step-by-step explanation:
If the total unit cost of manufacturing Product Y is currently $40 and the total unit cost after modifying the style is estimated to be $48, the differential cost for this situation is $8.
true
There are linear relationships so long as the power of x is 1 when power of y is 1 / power of x is not 2 and above when power of y is 1. This is assuming you plot the vertical axis as y-axis and the horizontal axis as the x-axis.
So using this concept, the equation with linear relationships are:
1, 3, 4, and 5.

A. Expanding the given expression, you have
balance = 75r^2 +150r +75
B. For r=0.10, the balance after 2 years is 75*1.1^2 = 90.75
C. The difference between $120 and 90.75 is $29.25. You need $29.25 more to buy the bicycle.
