Answer:
x = 18 <KLM = 40
Step-by-step explanation:
to find x:
2x + 4 = (2x-12) + (2x-20)
...
x=18
to find <KLM:
2(18)+4
=40
Answer:
Step-by-step explanation:
Given
Required
The linear function of a competitor's website
On day 1, both websites have the same subscribers.
This implies that:
Substitute:
This implies:
On day 34, both websites have the same subscribers.
This implies that:
Substitute:
This implies:
To calculate the linear function of the competitor, we have:
Calculate slope (m)
The equation is then calculated as:
This gives:
Open bracket
<em></em><em> --- This represents the linear function of the competitor's website</em>
Use this formula:
original amount - new amount
———————————————-
original amount
you just plug in the numbers in this formula now and solve
20-11 9
——— = —- = 0.45
20 20
multiply 0.45 by 100 to convert it into a percent
0.45 * 100 = 45
The answer is 45% !!
Answer:
-9m - 4 + 2m = -9 - 7m + 5
-7m - 4 = -7m - 4
-7m + 7m = -4 + 4
0 = 0
This is an identity solution because the same number equals the same number. That means there's an infinite set of solutions.
