Answer:
solutions of given system are (-2,4) and (2,0).
Step-by-step explanation:
We have given a system of equations.
y = x²-x-2
y = -x+2
We have to find solution of given system by graphing.
In graphing method, solution of a system is the points on graph where two lines intersect each other.
From attached graph, intersecting points are (-2,4) and (2,0).
Hence, solutions of given system are (-2,4) and (2,0).
Answer:
(-2,4) and (2,0)
Step-by-step explanation:
The graphical solution to the system of equations is simply the point(s) where the graphs of the function intersect or cross each other.
The graphs of the function can be found in the attachment below;
From the graph, the functions intersect at ;
(-2,4) and (2,0)
Answer:
4 [miles].
Step-by-step explanation:
1) the condition 'the entire trip took 5 hours' can be written as (where t_us - time spent upstream, t_ds - time spent downstream)
2) but the distance [D] upstream is equal the distance downstream, then the condition above can be written:
3) finally,
D=5*4/5=4 [miles].
