Answer:
This system of equations has <em>no solution</em>. It is inconsistent.
Step-by-step explanation:
The last equation tells you z = -1.
Substituting this value for z in the other two equations allows them to be written as ...
-3x -y = 7
-3x -y = 3
There are no values of x and y that can make both these equations true.
Answer:
5-3í
Step-by-step explanation:
Because the root of nine is three, equaling 5-3í
<span>Simplifying
8z + 3z = 8
Combine like terms: 8z + 3z = 11z
11z = 8
Solving
11z = 8
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Divide each side by '11'.
z = 0.7272727273
Simplifying
z = 0.7272727273</span>
Set up a ratio:
24 / 36 = x /12
cross multiply:
24 * 12 = 36 * x
288 = 36x
divide both sides by 36
x = 288 / 36
x = 8
answer is A) 8
