<span>–(2n + 4) + 6 = –9 + 4(2n + 1)
-2n - 4 + 6 = - 9 + 4*2n + 4*1
</span>
<span>-2n - 4 + 6 = - 9 + 8n + 4
Take all the n's to one side and numbers to the other side. Sign changes to + or - when equality sign is crossed to other side of equation.
</span>
<span>-2n - 8n = - 9 + 4 + 4 -6
-10n = -7
n = -7/-10
n = 7/10 or 0.7

Let's say that the temperature it changed is x.
4 (x) =-20.
So basically we're dividing -20 by four, because the temperature changed by -20 degrees over four weeks, so the answer is -5.
It's asking you to shift the graph of; y = 5x up 3 units. if you add 3 to the equation, all y-values will be increased by 3 this shifts the graph up exactly 3 units.
y = 5x + 3
Answer:
9% increase
Step-by-step explanation:
Given :
17% increase :
Let initial percentage = 100%
17% increase means :
100% + 17% = 117%
Followed by 8% decrease :
117% - 8% = 109%
Hence, the final percentage = 109%
To represent the total change as a single percentage change :
Change = final percentage - Initial percentage
Change = 109% - 100%
Change = 9%
This is a 9% increase
Answer:
Hey There!! The Correct answer is: The equation is w = 241(1.06)t
And here variable t represents the number of years since 2000.
In 2001 means t=2001 -2000 = 1
So we plug 1 for t in the given expression , that is w = 241(1.06)1 = 241 * 1.06 = 255.46
Therefore in 2001, it should be worth to 255.46.
And in the given expression 1.06=1 +0.06, where 0.06 is the annual percent of growth that is 6 % .
