Answer: x=−5/7
Step 1. Add 4x to both sides of the equation.
3x+4+4x=−4x−1+4x
7x+4=−1
Step 2. Now you subtract 4 from both sides.
7x+4−4=−1−4
7x=−5
Step 3. Then divide both sides by 7.
7x/7=-5/7
Final Answer: x=-5/7
Hope I could help! :)
Using laws of exponents,
9^(1/2) = 34^(-1/2) = (1/4)^(1/2) = 1/2
Therefore,9^(1/2)/(4^(-1/2)) = 3/(1/2) = 6.

Answer:
x= y-5
Step-by-step explanation:
Answer:
$962.82 will be in John's account after 8 years if compounded semiannually.
Step-by-step explanation:
The formula used to find the amount after 8 years is:
A = P(1+ r/n)^nt
Where A = future value
P= principal value
r = interest rate ( in decimals)
n = no of times interest is compounded
t = time
Putting the values:
P = $600
r = 6% = 0.06
n = 2
t = 8
A= 600 *(1+0.06/2) ^2(8)
A= 600 *(1.03) ^16
A =600*1.605
A = 962.82
So, $962.82 will be in John's account after 8 years if compounded semiannually.
