Answer:
-9/2
Step-by-step explanation:
-9 is the same as -9/1
if we multiply -9/1 and 1/2 we multiply the numerators to get -9 and multiply denominators to get 2 or -9/2

Lots and lots and lots and lots of math. :p
Basically just add 8.5% to each number 12 times
Explanation:
The solution set for a system of equation is the set of points where the graphs of the equations intersect.
__
<h3>general case</h3>
A system will have <em>one solution</em> if there is a <em>single point of intersection</em> of the graphs of the equations.
A system will have <em>no solutions</em> if the graphs have <em>no points of intersection</em>.
A system will have an <em>infinite</em> number of <em>solutions</em> if the graphs <em>intersect at an infinite number of points</em>.
_____
<h3>linear equations</h3>
When the equations are linear equations, their graphs are straight lines. If the lines have different slopes, they must intersect at exactly one point: there will be one solution.
If the lines have the same slope, there are two possibilities:
- the lines are parallel -- no solutions
- the lines are coincident -- infinite solutions
The attached graph illustrates these cases.
- the red and blue lines are the graphs of a system of equations with one solution. Those lines have different slopes
- the blue and green lines are the graphs of a system of equations with no solution. Those lines are parallel.
- The red and (dotted) purple lines are the graphs of a system of equations with infinite solutions. Those lines are coincident.
8,034 is rounded to 8,000. 4,981 is rounded to 5,000.
The answer is 8,000 - 5,000 = 3,000
