In this question, you are given the plane 1 speed(496miles/h), plane1 depart time(8:00), plane 2 speed(558miles/h) and plane2 depart time(8:30 or 8.5 hour). Both of the planes left from the same airport so their traveling distance should be same. They also arrive in same time. Then the equation would be:

duration = arriving time - depart time
duration1= x= arriving time - 8h
duration2= y= arriving time -8.5h= (arriving time - 8h) -0.5h= x-0.5h 

speed1 * duration1 = speed2 * duration2
496 * x = 558* (x-0.5)
496x = 558x - 279
279= 558x- 496x
279= 62x
x= 4.5hour

What is the slope of a trend line that passes through the points (–3, 3) and (18, 26)? StartFraction 15 Over 29 EndFraction Star
Alik [6]

Answer:

  23/21

Step-by-step explanation:

The slope is computed from ...

  m = (y2 -y1)/(x2 -x1)

For the given points, the slope is ...

  m = (26 -3)/(18-(-3)) = 23/21

The slope of the trend line is 23/21.

A triangle, ABC, has coordinates A (-2, 0), B (-2, 5) and C (-4, 0). What is the length of the shortest side?
Usimov [2.4K]

Answer: 2 units.

Step-by-step explanation: When you graph the points given, it gives you this shape in the image below.  The hypotenuse (longest side of triangle) is found by doing the following:

a^2 + b^2 = c^2, where a and b are the legs (the other sides of the triangle) and c is the hypotenuse.

5^2 + 2^2 = 29.

√ 29 ≈ 5.38, and that is the length of the hypotenuse.

The shortest side is the bottom side, which is 2 units.  Therefore, that is your answer.

Let me know if this is right! :)

Which equations show direct variation between x and y? Choose all answers that are correct. a 3x=7 b y=4.2/x c y/x=6 d y=0.5x +
anastassius [24]

a).  No.  Variation in 'y' has no effect on 'x'.

b).  No.  Variation in 'x' has exactly the opposite effect on 'y'.

c).  Yes.  Variation in 'x' causes 'y' to vary 6 times as much in the same direction.

d).  No.  Doubling 'x' does not double 'y'.

Write and equation of the line in slope intercept form that passes through the points. (0,1) (2,4)
Helen [10]
Y = 3x + 1

slope: (y2-y1)/(x2-x1) = (4-1)/(2-1) = 3/1 = 3

point slope form:
y-y1 = m (x-x1)
y-1 = 3 (x-0)
y-1 = 3x
y = 3x + 1
