1. Solve the following system by graphing and identify the point of intersection.
2.What is the solution to the system of equations?https://tcan4424-oakcliff-ccl.gradpoint.com/Resour...
3. Without graphing, classify the following system as independent, dependent, or inconsistent.
the point of intersection is (1,0)
Let add first equation to the third equation and we get:
the answer is x=16/5 , y= -1/5, z=1
If slopes are different, system is independent.
If slopes are same and intercepts are same, system is dependent.
If slopes are same and intercepts are not the same, system is inconsistent.
so the following system is independent
The answer choices for # 2 are :
a. (2, 1, –1)
b. (–2, 1, 1)
c. (2, –1, 1)
d. (2, 1, 1)
Just one moment
Let subtract third equation from the firs equation and we get:
answer is d. (2, 1, 1)
Sorry, I did mistake in previous solution
