Write a number in each blank to complete each equation so that it has the requested number of solutions. a. Equation with no sol

Setler79 [48]

Answer:

The answer is 8 $x$ - 3 $x$ + 2 - $x$ = 4  $x$ + 2  .

Step-by-step explanation:

Given:

8x - 3x + 2 -x = __ x + __

Now, to write a number in each blank to complete each equation so that it has the requested number of solutions.

So, to solve the equation:

$8x-3x+2-x$

So, we add the variables:

$5x+2-x$

And, then subtract it:

$4x-2.$

Thus, it remains:

$4x-2$ .

So the complete equation is:

8 $x$ - 3 $x$ + 2 - $x$ = 4 $x$ + 2

Therefore, the answer is 8 $x$ - 3 $x$ + 2 - $x$ = 4  $x$ + 2  .

Determine the kinetic energy of 8000 Newton’s roller coaster car that is moving with a speed of 20.0 meters/seconds

ohaa [14]

Answer:

The kinetic energy of the roller coaster is 1600000 J.

Step-by-step explanation:

Given:

Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.

Now, we need to find the kinetic energy $E_{k}$ of the roller coaster.

So, Mass of roller coaster (m) = 8000 N.

Velocity of roller coaster (v) = 20.0 m/s.

Now, putting the formula of kinetic energy:

$E_{k} = \frac{1}{2}\times m\times v^{2}$

$E_{k}=\frac{1}{2} \times 8000\times 20^{2}$

$E_{k}=\frac{1}{2} \times 8000\times 400$

$E_{k}=\frac{1}{2} \times 3200000$

$E_{k}=1600000$

Therefore, the kinetic energy of the roller coaster is 1600000 J.
