How many solutions exist for the system of equations below?
2 answers:
Answer:
0 (None) solutions
Step-by-step explanation:
This Linear System has no Solution. It means that mathematically speaking, whatever value inserted for x, or y this will not result in an equality, i.e. we'll always have a false value. Like this:
FALSE Because then This Linear System does not have solution.
Geometrically, both equations are parallel lines, so they do not have any common point, i.e. solution. Notice they both have the same slope. Check the graph below.

Given : A social media website has currently = 1,000 members.
In each month number of members gets triple.
To find: Equation that represents number of members m belongs to site.
Solution: Because we are given, each month the number of members gets triple, that means each month we can multiply by 3 to the number of members of previous month.
For first month, we would multiply 1,000 by 3.
For second month, we would multiply 1,000 by 3 *3.
For second month, we would multiply 1,000 by 3*3*3.
Each month one factor of 3 is being increasing.
We could write those 3's as exponents of 3.
Like
As many months as many 3's are there.
So, the exponent of 3 is represnts the number of months.
Let us take a variable for number of month by n.
So, we could setup an equation for number of members m belongs to site on a particular month n as
This is our final equation.
Answer:
-60% decrease
Step-by-step explanation:
60 is the old value and 24 is the new value.
percent change = x 100%
so for this problem, you can substitute the values given in the formula:
percent change = x 100% =
x 100% =
-60% (decrease)
