Which ordered pair is a solution of inequalities?
1 answer:
Answer:
B is the only solution
Step-by-step explanation:
These inequalities are shown in the attached picture. Which can be obtained drawing y > -2 (an horizontal line at y=-2, the region is above). and y<= 4-x, a line with a negative slope of -1 and intercept point of 4.
Any ordered pair, located inside the interception between these two regions is a solution of the system.
A. is Outside, below the horizontal line
B. is not clear by graph, hence, lets evaluate it in both inequalities
3>-2 (satisfies)
1+3<=4 (satisfies)
Hence B is a solution.
C. Is outside, we can evaluate it just to make sure:
5>-2 (satisfies)
1+5<= 4 (not true)
Hence C is not a solution.
D. is outside

As we know that in a triangle
- Substitute the value
Graphs can be used to model real world situations.
<em>The coordinates of the graph is gotten by adding 5 to the y-values of the function (see attachment for graph)</em>
The function of the graph is represented as (n, f(n)); where
<em /><em> speed</em>
<em /><em> fine for over speed</em>
When the fine increases by $5 for every speed limit.'
The new function becomes:
<u />
<u>The points on the graph are represented as:</u>
So, the new points would be calculated as follows:
See attachment for the new graph
