The formula that shows the relationship between the distance, rate and time is t = d/r and t = 5.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.
Given that:
d = rt
Hence:
t = d/r
For d = 40, r = 8:
t = 40 / 8
t = 5
The formula that shows the relationship between the distance, rate and time is t = d/r and t = 5.

Answer:
B) -1 and D) 1
Step-by-step explanation:
We want to find the solution to

Which means that we want to find the values of x at which the two functions f(x) and g(x) are equal.
In order to do that, we have to look at the table, and see at which values of x the two functions have the same value.
We observe that the only two values at which this occurs are:
at
, where both functions are equal to 
at
, where both functions are equal to 
For a cartesian equation

Given r = <span>10 tan(θ) sec(θ)

Therefore,</span>the curve is a parabola opening upward with vertex (0, 0).
Answer: y-1=6(x+7)
Step-by-step explanation:
The formula for point-slope form is
. Since we are given the point and slope, we can directly plug them in.
[distribute by -1]

Now, we know that the point-slope form is y-1=6(x+7).
