Answer:
So we can first use the distance formula which is for 2 dimensional but seen as we're in 1 dimensions we dont have to use it. So we can just get the distance between them using a formula I made -
|a-d| = distance
So if we use that formula we can get that -7-(-2) = -7+2 = -5. Then take the absolute value which is 5.
Therefore the answer is
<h2><u>
5 is answer</u></h2>
Well, if you were looking for the value of 5, it's 50 in this case. And if you're looking the value of 8 it's 8.
-5a - 12a can also be rewritten as:
-5a + -12a, which would equal -17a
Answer:
4 mph
Step-by-step explanation:
Travel time is proportional to distance and inversely proportional to speed. If c represents the speed of the current in miles per hour, an equation for the total trip time is ...
825/(29 -c) +825/(29 +c) = 58 . . . . . . hours travel time
825(29 +c) +825(29 -c) = 58(29 -c)(29 +c)
58c² -928 = 0 . . . . . . . rearrange to standard form
58(c -4)(c +4) = 0 . . . . factor
Values of c that satisfy this equation are 4 and -4. For the purpose here, we'll choose the positive solution.
The speed of the current is 4 miles per hour.
