The formula for t=s/(v₁+v₂), and the value of t is 2 hours.

Step-by-step explanation:

The question is on relative speed.

For the two trains moving towards each other , the relative speed is the sum of their speeds.

Distance between the cities= s miles

Train 1 : speed is v₁ mph

Train 2: speed is v₂ mph

Time of meeting= t

Applying formula for speed, speed =distance/time

Time of meeting= Distance/relative speed

t=s/(v₁+v₂)

Given s=310, v₁=75 and v₂=80, then finding t

t=310/(75+80)

t=310/155 = 2 hrs

Answer:

-8

Step-by-step explanation:

First we need to find the slope of CD.

We know C is (-10, -2)

and we know D is (10,6)

If we use the slope formula, we can see the slope is $m=\frac{6-(-2)}{10-(-10)}$

$m = \frac{8}{20} \\m=\frac{2}{5}$

We can see point F is at (6,-4)

We can find the equation of this line by using point slope form, and plugging in F as our point.

$y-(-4)=\frac{2}{5}(x-6)\\y=\frac{2}{5}x-\frac{32}{5}$

To find where E, we need to find the y value when x = -4

$y=\frac{2}{5}(-4)-\frac{32}{5}\\y =-8$

Firdavs [7]

The <em>correct answer</em> is:

D) reflect over the y axis and then reflect again over the y axis.

Explanation:

Logically, if we reflect a figure across the y-axis and then reflect across the y-axis again, we have undone what we originally did, and the figure is back in its original position.

Algebraically, reflecting across the y-axis maps every point (x, y) to (-x, y). Reflecting this point across the y-axis maps (-x, y) to (x, y); this is our original point.
