Answer:
Hey there!
We are trying to find the difference between 4 and -7
We can write -7+x=4, where x is the difference we are trying to find.
Solving for x, we get that the difference is 11.
Let me know if this helps :)
Answer:
It will take about 35.439 years to triple.
Step-by-step explanation:
Recall the formula for continuously compounded interest:
where "A" is the total (accrued or future) accumulated value, "r" is the rate (in our case 0.031 which is the decimal form of 3.1%), "P" is the principal, and "t" is the time in years (our unknown).
Notice also that even that the final amount we want to get is three times $48,000. So our formula becomes:
Now,in order to solve for "t" (which is in the exponent, we use logarithms:
The answer is : y = -3x + 1
Move all terms that don't contain y to the right side and solve.
y = 3 − 2x
The inverse of f(x)=3x+1 is f(x)−1=13x−13 .
