1/2x-9=-25 what is your answer

Elodia [21]

First, let's only the expression with x stay on the let side: let's add 9 to both sides of the equation.

$\frac{1}{2} x-9+9=-25+9$
which is
$\frac{1}{2}x=-16$

now, let's multiply everything by 2:

$\frac{2}{2} x=-16*2$
$x=-32$

so the answer is -32!

Marcel is performing the first test on his company's new electric car. During the test, the electric car reaches a maximum speed

valentina_108 [34]

Answer:

C. The electric car is not moving at 0 seconds and 12 seconds.

Step-by-step explanation:

Given:

The table given is:

x 0 2 4 6 8 10 12

y 0 45 72 81 72 45 0

From the above table, we observe that the car starts from rest and its speed increases from 0 to 6 seconds, the maximum speed being 81 mph.

After 6 seconds, the speed of the car goes on decreasing till it stops at time equal to 12 seconds.

So, the speed of the car at the start when $x=0$ is 0 mph as it is at rest at that time.

Also, when the time is $x=12\ s$ , the car has come to a stop and thus its speed has reduced to 0 mph again. So, the car is not moving after 12 seconds.
