Not rlly sure, might be x=4/5y??? i dont know
Answer:
(1/7, 1)
Step-by-step explanation:
By "answer," you probably meant "solution." What is the "solution of the system of linear equations
- 5y = - 5
+ 7x +6y=7
The first eqation can be solved for y: y = 1. Substitute 1 for y in the secon equation. Then 7x + 6(1) = 7, or 7x = 1, or x = 1/7.
The solution to this system is (1/7, 1)
Answer:

Answer: 49
Step-by-step explanation:
a=1 ,b=14, c=?
b^2-4ac =0
(14)^2-4(1)(c)=0
196-4c=0
196=4c
c=49
Check:
(x)^2+2(x)(7)+(7)^2
x^2+14x+49
(x+7)^2
2x =3 is the first one , first one is B and 2nd one is D I believe
