Answer:
k = 4
Step-by-step explanation:
7k - 6 = 2k + 14
(7k - 2k) - 6 = (2k - 2k) + 14
5k - 6 = 14
5k (- 6 + 6) = 14 + 6
5k = 20
5k/5 = 20/5
k = 4
Answer:
<u>Equation</u>: 
<u>The balance after 5 years is: $1742.43</u>
<u></u>
Step-by-step explanation:
This is a compound growth problem . THe formula is:

Where
F is future amount
P is present amount
r is rate of interest, annually
n is the number of compounding per year
t is the time in years
Given:
P = 1500
r = 0.03
n = 12 (compounded monthly means 12 times a year)
The compound interest formula modelled by the variables is:

Now, we want balance after 5 years, so t = 5, substituting, we get:

<u>The balance after 5 years is: $1742.43</u>
Answer:what’s the initial age
Step-by-step explanation:
For a function to be odd f(-x)=-f(x).
1) putting x as -x
f(-x)= -x^3+x^2 = -f(x)
Thus, this is an odd function.
2) Following the same procedure,
f(-x)= -x^5+3x^3-2x =-f(x)
Thus, this is an odd function.
3) Again,
f(-x)= -4x-9 = -f(x)
This also is an odd function.
Hope this helps :)
