Answer:
Solution = (-8,-28)
Step-by-step explanation:
B is the one I would go with, multiplying everything by 3 in the equation 3 would eliminate y.
The shape has 7 sides.
The sum of the interior angles is (7-2)180 = 5 * 180 = 900 degrees.
Divide the total sum by 7:
X = 900 /7 = 128.6 degrees.
i believe the correct graph is the bottom left
Answer: the answer is b.
Step-by-step explanation: if you read the graph, you will see number of square feet, X the third one over you will see 100 over 40 and if you duplicate both then you get 200 for the number of square feet and 80 minutes, I hop this helps ツ.
