First you distribute, you will be left with 8s-12=3s+1
then you will add 12 on each sides, and subtract 3s on each side, you'll be left with 5s=11 then you will divide by 5 on each sides s=2.2
It’s blurry I can’t see it
For -(4)^7
the - is not affected by the power of 7
For (-4)to the power of7 is the same as -4 to the power of 7
It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7
But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4
I am not good at English if there is any things that you feel confused you may ask
So this is going to be an exponential equation, which the format is
, in which a is the initial value and b is the growth/decay rate.
In this case, a is going to be 340,000 and b is going to be 107%, or 1.07, since the population is going to be increasing by 7% and the equation is now
.
Now replace x with 12 and solve.
Solve
, and then if you don't round that answer and multiply it with 340000 you get
.
Answer:
4900%
Step-by-step explanation:
the increase is 100-2=98 pounds
98=p/100 * 2
2p=98*100
p=9800/2
p=4900
