Step-by-step explanation:
What is the solution to this equation?
(1/4)^x+1 =32
A.) -2
B.)7/-2
C.)2
D.) 3/2
Answer:
It would be 6
Step-by-step explanation:
The answer is no it will be less here's why let say the original amount is A then a p% increase will be A(1+p/100))
Now from this amount we decrease it by p% this gives A(1+p/100)(1-p/100). We can simplify this expression some by letting x=p/100 then we have A(1+x)(1-x) but this is equal to A(1-x2). You can see that the value of what's inside the () is always <1 as long as x>0. If we calculate how much the amount changes we have A(1-x2)-A=-Ax2 is always a loss.
This is one of the reasons some people lose money in the stock market. If a stock rises 10% and then drops 10% you have actually lost money but it sounds, on the face of it, like you should be even. +10 and -10 percent.
If we now do the calculation for the 25% up and down we have the final amount is is .9375 which is 1.25*.75. and the change is .9375-1=-.0625. So the net result is down 6.25%
Answer:
Option C, y = -1/3x + 2
Step-by-step explanation:
2x + 6y = 12
<u>Step 1: Solve for y</u>
2x + 6y - 2x = 12 - 2x
6y / 6 = (12 - 2x) / 6
y = 2 - 1/3x
Answer: Option C, y = -1/3x + 2
