Answer:
D. 6
Step-by-step explanation:
The system can be solved by subtracting double the second equation from the first:
... (4x +3y) -2(2x +y) = (20) -2(7)
... y = 6 . . . . . . . . . for solution (x, y) = (a, b), this tells you b=6.
Putting this into the second equation gives ...
... 2x +6 = 7
... 2x = 1
... x = 1/2
The solution is (x, y) = (a, b) = (1/2, 6). b = 6.
Answer:
inductive
Step-by-step explanation:
Inductive reasoning is based on generalization, and making conclusions without hard evidence. If Micheal has red hair and is from Chicago, inductive reasoning draws the conclusion that everyone in Chicago has red hair. Deductive reasoning would be predicting that everyone in Chicago has red hair, and then testing it to see if you are right.

Answer:
x=0 x=2
Step-by-step explanation:
4x=y
2x^2-y=0
If y=4x you can use substitution
2x^2-4x=0
2x(x-2)=0
2x=0 x-2=0
x=0 x=2
