Let f(x) = 2x+4. If f(x) = 16, find x.

jeyben [28]

$f(x)=2x+4$

And we are given that $f(x)=16$ and want to find the value of x. Set f(x) to 16 and we get the equation:

$2x+4=16$

Subtract both sides by 4

$2x=12$

Divide both sides by 2

$x=6$

This is the answer. Let me know if you need any clarifications, thanks!

Amir pits £3035 into a bank account. The account pays 4% compound interest each year. Work out how much money amir will have in

myrzilka [38]

Answer:

$\£3840.2$

Step-by-step explanation:

Let P denotes principal amount, T denotes time period and R denotes rate of interest.

Amount = $P(1+\frac{R}{100})^T$

Amir pits £3035 into a bank account. The account pays 4% compound interest each year.

Put $P=\£3035,\,R=4\%,\,T=6$

Amount = $3035(1+\frac{4}{100})^6=3035(\frac{104}{100})^6=\£3840.2$

Therefore, Amir will have $\£3840.2$ in the account after 6 years.

Answer:

Step-by-step explanation:

It's hard to tell what you mean. I'm going to assume you mean that you want what is left to be 3/7 less.
