Answer:
Option B) (-1,7,5) is correct.
The solution to the given system of equation is (-1,7,5)
Step-by-step explanation:
Given system of equations are



To find the solution of the given system of equations by using Elimination method:
Now adding equations (1) and (2)


_________________

________________


(since "-" getting cancelled)
Now adding equations (1) and (3)


_________________

________________



Now adding equations (4) and (5)


_________________

________________

Therefore y=7
Substituting y=7 in equation (4)




Therefore x=-1
Now substituting the values x=-1 and y=7 in equation (1) we get




Therefore z=5
Therefore the solution to the given system of equation is (-1,7,5)
Therefore Option B) (-1,7,5) is correct.
Standard form is a+bi where a and b are real numbers
remeber that i²=-1
ok

we got to get the i out of the denomenator
remember the differnce of 2 perfect squares where (a-b)(a+b)=a²-b²
so multiply the whole thing by

we get


in standard form, it is
Answer: .697
Step-by-step explanation:
A2+B2=C2
1/3 2+ 4/9 2= .697
