What you need to do is the distributive property to start with this problem

-7(8n-m)

Multiply -7 inside the parentheses, which it will turn out to be -56n

Then you should put an addition operation on -7 and -m

-56n+7m

You shouldn’t really do anything else to these variables because they are different. So just leave it to that

Avery invested $200 in an account paying an interest rate of 6 7/8%
Maslowich

Answer:

0.73 yrs

Step-by-step explanation:

if t is time in years

quarterly

600 = 200(1 + 0.06625/4)^4t

3 = (1 + 0.06625/4)^4t

ln3 = 4tln(1. + 06625/4)

t = ln3 / (4ln1.0165625)

t = 16.7198 yrs

continuously

600 = 200e^(0.06875t)

3 = e^(0.06875t)

ln3 = 0.06875t

t = ln3 / 0.06875

t = 15.9798 years

Δt = 16.7198 - 15.9798 = 0.73 yrs

Rewrite ^3 sqrt 27x-81-5 to make it easy to graph a translation. Describe the graph.
iragen [17]
First we have to rewrite this function.Instead of :^3 sqrt (...) we can write : (...)^(1/3).
f ( x ) = ( 27 x - 81 ) ^(1/3) - 5 = ( 27 * ( x - 3 ) ) ^(1/3) - 5 = = 3 * ( x - 3 )^(1/3) - 5 And this makes it easy to graph a translation.The parent function is y = x^(1/3). The zero of this function is ( 0, 0 ).
Then it will be stretched vertically by a factor of 2 and translated: 3 units right and 5 units down.
