i hope this helps :)
Does x need to be plugged in?
Answer:
The first option so
is the answer
<u>Skills required: Graphing Knowledge, Systems Knowledge</u>
Step-by-step explanation:
1) The solution to any system is the intersection between any 2 lines or functions. In this case, we are given two functions on a graph, and need to find the solution to them. That is the intersection.
2) We can see the intersection and see that the x-axis value for the coordinate point is around 3 1/2 (or 3.5 -- whatever you prefer), and that the y-axis value for the point is -4.
Therefore, the coordinate point is:
since this answer best matches the coordinate values of that point.

Select the first option, have a nice day! :D
Set up;
(15^2)(CB) = (7.5^2)/(ST)
(15^2)/(5) = (7.5^2)/(ST)
Cross-multiply to find ST.
