Answer:
1oc IS ur answer
Step-by-step explanation:
i think
GRAPHING CONS
1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.
2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.
3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution
SUBSTITUTION CONS
1) Becomes tedious if a system has too many equations or variables
ELIMINATION PROS/CONS
1) basically same as substitution
Y = 3x + 10
This equation is written in slope intercept form, which is y=mx+b. M equals the slope and b = the y intercept. So in your case, 3 is the slope and 10 is the y intercept.
I don't know what coordinate form is, but I hope that this helped you a little bit.
I'm assuming by overlined you meant repeating as when there is a repeating number in a decimal, it has a line over it to represent such.
In the quotient of 4 divided by 7, there are zero numbers overlined. This is because the answer is .5714285714, no numbers are consecutively repeating for a long or the rest of the number.
Hope this helps!
Answer:
(x, y) = (-1.4, 1.6)
Step-by-step explanation:
The graph shows the solution pretty clearly. It seems no estimation is required.
