Answer:
you better do go good on the assments
Step-by-step explanation:
<span>No. Of hours after passenger train passed the station x:
</span>52x = 32(x + 2)
<span>13x = 8(x + 2) </span>
<span>13x = 8x + 16 </span>
<span>5x = 16 </span>
<span>x = 16/5 or 3 1/5
</span>
Answer:
<span>3 1/5 hours OR 3 hrs 12 min
</span>
Hope this helps!

Answer: 2</h3>
Explanation:
The range is y ≤ 2 which means that y = 2 is the largest y can get. The parabola opens downward to form a sort of "frowny face" so to speak. When moving down the parabola, we'll cross the x axis at two different spots. An example of this is shown below with the equation y = -x^2+2.
There's no connection between the '2' in y ≤ 2 and the final answer of 2 roots. We could easily have a range of something like y ≤ 5 or y ≤ 8 and the answer will still remain as 2. The most roots a parabola can have is 2.
The midpoint of the segment shown below is (1, -3/2). Option A) is the correct answer.
<u>Step-by-step explanation</u>:
The two end points of the line segments are (1,2) and (1,-5).
<u>step 1</u> :
Midpoint formula = ((x1 + x2)/2 , (y1 +y 2)/2)
<u>step 2</u> :
(x1, y1) = (1, 2)
(x2, y2) = (1, -5)
<u>step 3</u> :
Substitute the values in the midpoint formula,
Midpoint = ((1 + 1)/2 , (2 -5)/2)
= ((2/2) , (-3/2))
= (1, -3/2)
