13/17 is the answer. Hope this helps :)
For number 1, you would have to subtract five on both sides to get 3x is greater than or equal to 15, then you would have to make the variable (x) on its own. So, you would divide 3x by three and 15 by three to get x=5.
I am not sure if you want me to do number two, but i will do it anyways, so 8(x+4) =-8, first you would have to multiply the eight into the parenthesis, so it would be 8x +32+-8 and then you would subtract 32 on both sides to get 8x=-40 you then divide -40 by 8 and you get x is greater than -5

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 is 0 mph as it is at rest at that time.
Also, when the time is , 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.
From the above conclusion, we can say that only option C is correct.
The electric car is not moving at 0 seconds and 12 seconds.
