The answer would be choice A. 2
The answer would be -8000 considering that the opposite of a positive ratio would have to be a negative ratio. If you used absolute value, 8000 and -8000 are the same distance away from zero, so -8000 would be your answer.
Answer:
and 
Step-by-step explanation:
Given:
.......................... equation i
........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have

Add
to both sides , we have


subtract 3 from both sides , we have

divide both sides by 4 , then

substitute
into equation i to get the value of y , that is



Therefore :
and 
5 3/4 * 10 =
23/4 * 10 =
230/4 =
57.5 or 57 1/2...same as 57 2/4 miles
