Answer:
Dependent variable: total distance (d)
Independent variable: number of hours (h)
Equation: d = 6h
Step-by-step explanation:
In this case given, the dependent variable, total distance (d), is dependent on the independent variable, number of hours (h). This is because, a change in the value of h leads to the change in the value of d. In order words, total distance (d) is a function of the number of hours (h).
Therefore:
Dependent variable: total distance (d)
Independent variable: number of hours (h)
Rate: 6 miles/hr
Equation: d = 6h
Answer:
-918.55
Step-by-step explanation:
2x + 7 = 15
Get 2x by itself
Take away 7 from both sides.
2x = 8
Divide both sides by 2, or multiply both sides by 0.5.
x = 4.
Your answer is C.)
Answer: 
-3 times the square root of 5
=============================================
Explanation:
Let 
Replace all the root 5 terms with x and we go from

to

From here, combine like terms to get

and the last thing to do is replace the x with sqrt(5)

Meaning that,
