Answer:
All positive real numbers
Step-by-step explanation:
Given
The model can be represented as:
[tex]y = f(x)[/tex]
[tex]y = distance[/tex]
[tex]x = time[/tex]
Required
Determine the domain
This means that we list out possible values of x.
If x represents time, then it is impossible for x to be negative.
This implies that x can take any value as long as it is greater than or equal to 0.
Hence, the domain is all positive real numbers

I'm not sure if this is completely correct, but:
We have this equation, logarithm base 10 of x, which is equal to y.
This equation can be reorganized like this: [tex]10^{y}[/tex] = x, or 10 to the y power is equal to x.
y represents the power that 10 (the base) is raised to, while x represents the result of [tex]10^{y}[/tex] (the base to the power of y).

Which equation represents the line with a slope of 5/6 that passes through the point (−2,1)?
Answer:
y = 5/6x + 8/3
Step-by-step explanation:
Remember that the slope intercept formula is:
y = mx + b (m is the slope and b is the y-intercept)
We know that slope = 5/6 therefore m = 5/6
So far we have the equation: y =5/6x + b
Now we must find b
To do that, you must plug in the point the line goes through in the x and y of the equation. Point (-2, 1) go through the equation:
y = 5/6x + b
1 = 5/6(-2) + b
Now solve for b
First, you will multiply 5/6 by -2
1 = -5/3 + b
Add 5/3 to both sides
1 + 5/3 = -5/3 + 5/3 + b
8/3 = b
Now that we have b, we can now complete the equation.
y = 5/6x + 8/3
The equation which represents line with slope 5 / 6 and passes through the point ( - 2 , 1 ) is y = 5 / 6 x + 8 / 3
What is a Linear Equation?
A linear equation is an algebraic equation of the form y = m x+ c involving only a constant and a first-order (linear) term, where m is the slope and c is the y-intercept.
Given data ,
Slope of the equation m = 5 / 6
Line passes through the point P ( x , y ) = P ( -2 , 1)
So the linear equation is y = m x + c
Substituting the value of slope m in equation , we get
y = ( 5 / 6 ) x + c
Substituting the values of x and y from the point P ( x , y ) = P ( -2 , 1) , we get
1 = ( 5 / 6 ) × ( - 2 ) + c
1 = ( - 5 / 3 ) + c
c = 1 + ( 5 / 3 )
And c = 8 / 3
Therefore , the equation y = m x + c becomes , y = ( 5 / 6 ) x + 8 / 3
Hence , the equation which represents line with slope 5 / 6 and passes through the point ( - 2 , 1 ) is y = 5 / 6 x + 8 / 3

Step-by-step explanation:
To compare two fractions one has to convert them to a common denominator (number underneath the fraction bar). This can be done by finding the LCM (least common multiple) of the two denominators, and then multiplying the numerator and denominator of each respective fraction such that the fraction's denominators are the same. Now all one has to do is compare the numerators, the numerator with a greater value indicates that the fraction is larger.
