The number is -1.
5x+2 = x-2
X=-1
P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use all 100 sheets of paper;
Therefore;
if p(t)=0
Then:
-8t+100=0
We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5
Answer: the printer prints 100 sheets of paper in 12.5 minutes.
Answer:
x would equal -8.
Step-by-step explanation:
1. combine like terms, and add -6x+5x, leaving you with -1x
2. add +4 to the other side of the equal sign, because to get rid of a negative you need to divide.
3.once you add the 4 over to the other side, the equation you should now be left with is -1x=8.
4. divide both sides of the equal sign by negative 1, and 8 divided by -1 should be -8, and thats the value of x.
Answer:
The correct answer is 
. The exponent 
is wrong since the decimal place was moved six from the right. Additionally, the exponent number isn't dependent on the amount of zeros, but the amount of times the decimal place was moved.
Step-by-step explanation:
Each place you move the decimal, you have to add or subtract one to the exponent.
If you move the decimal place towards the left, you add one.
If you move the decimal place toward the right, you subtract one.
The exponent number isn't dependent on the amount of zeros, but the amount of times you moved the decimal place. To get from 2,320,000 you must move the decimal place 6 times to the left to get 2.32. Hopes this helps!
