Answer:
The slope of the line will change from negative to positive
Step-by-step explanation:
The equation of the line, y = -⁵/4 x + 3, is written in the slope-intercept form, which is y = mx + b. Where,
Slope = m, which means the slope of the line is -⁵/4,
y-intercept = b, which means the y-intercept of the line is 3.
Therefore, if -⁵/4 is changed to ⁵/4, the slope has been changed from negative to positive. Therefore, the graph of the slope of the line will change from negative to positive.
The answer is (4x11)-7 i believe
Let's define variables:
s = original speed
s + 12 = faster speed
The time for the half of the route is:
60 / s
The time for the second half of the route is:
60 / (s + 12)
The equation for the time of the trip is:
60 / s + 60 / (s + 12) + 1/6 = 120 / s
Where,
1/6: held up for 10 minutes (in hours).
Rewriting the equation we have:
6s (60) + s (s + 12) = 60 * 6 (s + 12)
360s + s ^ 2 + 12s = 360s + 4320
s ^ 2 + 12s = 4320
s ^ 2 + 12s - 4320 = 0
We factor the equation:
(s + 72) (s-60) = 0
We take the positive root so that the problem makes physical sense.
s = 60 Km / h
Answer:
The original speed of the train before it was held up is:
s = 60 Km / h
Answer: son, estoy, estas, es, son, estamos, son, estan
Step-by-step explanation:
If it is talking about someone else then try to use, son. Like the first one. For words for yo use words like estoy. I don´t really know how to explain them but they make sense.
