Answer:
Step-by-step explanation:
1. Find the function's zeros and vertical asymptotes, and plot them on a number line.
2. Choose test numbers to the left and right of each of these places, and find the value of the function at each test number.
3.Use test numbers to find where the function is positive and where it is negative.
4. Sketchh the function's graph, plotting additional points as guides as needed.

Answer:
x=-7.88
y=-32.35
the point answer would be (-7.88 , -32.35)
Step-by-step explanation:
First step is to multiply 3x+y=-56 by 4 and you get 12x+4y=-224
Then add each equation together to eliminate y from each equation. You get 17x=-134
Then find divide that equation by 17. You would get x=-7.88
Then plug -7.88 into one of the original equations for x. 5(-7.88)-4y=90 And from that you get -39.4-4y=90
Then isolate the y variable. You would get -4y=129.4
Then divide by -4 and get y=-32.35
So 64/100 /2=32/50 then 32/50 /2=16/25 so 1 16/25
Just add 16 to -3, then that will get your answer 13.
