Answer:
A
Step-by-step explanation:
You do distance over time to get the rate, so you'd do 27/2= 13.5mph then divide that in half since you're asking for the distance traveled in half that hour so you do 13.5/2 and you get 6.75 miles traveled in half and hour.
Answer:
parallel
Step-by-step explanation:
An equation of the form
y = k
where k is a number is a horizontal line.
Since both lines have the form y = k, with two different values of k, -2 and -7, these are two different horizontal lines, so they are parallel.
Answer: parallel
Answer:
Step-by-step explanation:
The sum of an infinite geometric series is expressed according to the formula;
where;
a is the first term of the series
r is the common ratio
If the sum of an infinite geometric series is three times the first term, this is expressed as 
Substitute into the formula above to get the common ratio r;
open the parenthesis
subtract 3 from both sides
<em>Hence the common ratio of this series is </em><em></em>
