Answer:

"undefined"

Step-by-step explanation:

Slope is computed as "rise/run." For the given points, the rise is 7, but the run is 0, so the rise/run is 7/0. Division by zero gives an "undefined" result, so we say the slope is "undefined."

_____

The line is a vertical line: x = -10.

By using the remainder theorem, determine the remainder when

Greeley [361]

Answer:

-123

Step-by-step explanation:

The remainder theorem says that when a polynomial is divided by a linear factor x - c (note the minus sign), the remainder is the value of the polynomial at x = c.

When a polynomial P(x) is divided by x - c, the remainder is P(c). In other words, to find the remainder, plug in c for x.

You're dividing by x + 4 which is the same thing as x - (-4) -- the role of c is being played by -4.

3(–4)^3 – (–4)^2 – 20(–4) + 5 = –123

The distance between the cities Chicago and Toronto is 540 miles. A motorcycle's speed is 48 mph. For a car, it takes 2.25 hours

serious [3.7K]

Answer:

5 hours

Step-by-step explanation:

given :

Distance between the cities = 540 miles

Speed of motorcycle =48 mph

TO CALCULATE THE TIME TAKEN BY MOTORCYCLE TO COVER THE TOTAL DISTANCE WE USE THE FORMULA :

$\frac{DISTANCE}{SPEED}$

By putting given values in the formula we get :

$\frac{540}{48}$

= 11.25 hours

Now, We are given that for a car to cover the same distance it takes 2.25 hours less than the time taken by motorcycle

⇒ 11.25 hours - 2.25 hours

⇒ 9 hours

Thus , Time taken by car to cover the same distance is 9 hours .

Now to calculate speed of car by using formula:

$\frac{distance}{time}$

$\frac{540}{9}$

= 60 mph

Let t be the time taken to meet if they start moving towards each other.

So distance covered by motorcycle in t hours is

speed\times time

= 48t miles

Distance covered by car in t hours is

speed\times time

= 60t miles

⇒ 60t + 48t =540

⇒ 108t = 540

⇒ t= 5 hours

Therefore, time taken to meet if they start moving towards each other is 5 hours.

In this generation are teens more likely to end their life’s because of bullying ? Why or why not.

klio [65]

Answer:

yes.

Step-by-step explanation:

Nowadays teenagers share their entire lives on social media. This can cause a feeling of being excluded and left out. Teenagers also can be bullied online and harassed by others, but those people who are harming them won't usually be caught because now everything is behind a screen. There are also very high rates of depression and anxiety among teenagers nowadays as well, with many growing up post 9/11 and used to a world of chaos and terrorism.
