I think it is the third one have a beautiful day Remeber you are awesome beautiful and loved
The correct answer is y=-2
I hope this helps :)
Answer:
A
Step-by-step explanation:
-x + 2y = 8
5x + 2y = -4
+ x. -2y. -8
6x = -12
÷6. ÷6
x = -2
5(-2) + 2y = -4
-10 + 2y = -4
+10. +10
2y = 6
÷2. ÷2
y = 3
Given the distance travelled and the time elapsed, the average speed of the train is approximately 1.63 miles per minutes.
<h3>What is the average speed of the train?</h3>
Given that;
- Distance traveled d = 75miles
- Time elapsed t = 46 min
- Average speed s = ?
Average speed = distance traveled / elapsed time
Average speed = 75miles / 46min
Average speed = 1.63 miles per minutes
Given the distance travelled and the time elapsed, the average speed of the train is approximately 1.63 miles per minutes.

Base leg (b) = 6
Other leg (a) = 14
Hypotenuse (c) = c
plug this into the equation above and solve for c (taking the square root to solve) so:
142 + 62 = c2
232 = c2
15.23 = c (feet)
Hope this helps have a good day. :)
