For the function m(n)=4n-7, when m is 9 what is n?

klio [65]

Answer:

n = 4

Step-by-step explanation:

Put the given values in the equation and solve for n.

9 = 4n -7

16 = 4n . . . . . . add 7

4 = n . . . . . . . . divide by 4

The value of n is 4 so that m(4) = 9.

1. Jeremy has $12000 cash to invest in the bank compounded at 4% interest annually.

gavmur [86]

Answer:

$A(x) = 12000(1.04)^x$

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$12000 cash

This means that $P = 12000$

Compounded at 4% interest annually.

This means that $r = 0.04, n = 1$

What equation will calculate the value in x years?

$A(t) = P(1 + \frac{r}{n})^{nt}$

$A(x) = P(1 + \frac{r}{n})^{nx}$

$A(x) = 12000(1 + 0.04)^x$

$A(x) = 12000(1.04)^x$

What are the rules to solving equations by multiplying or dividing?

Andreas93 [3]

Answer:

In order to move a number that is multiplied or divided by the variable, make sure to inverse both sides! That means, if the number is multiplied, you divide it by both sides. If it's divided, you must multiply it by both side; steps so that you can apply them to harder equations.

Sorry if this didn't help! I hope it did though, good luck. <3
