Answer:
x1 = t, x2 = -t and x3 = 0
Step-by-step explanation:
Given the system of equation
x1 + x2 + x3 = 0 .... 1
x1 + x2 + 9x3 = 0 .... 2
Subtract both equation
x3 - 9x3 = 0
-8x3 = 0
x3 = 0
Substitute x3 = 0 into equation 1
x1 + x2 + 0 = 0
x1+x2 = 0
x1 = -x2
Let t = x1
t = -x2
x2 = -t
Hence x1 = t, x2 = -t and x3 = 0

Answer:
The answers is n=35
Step-by-step explanation:
Solve for n by simplifying both sides of the equation. Then isolating the variable.
J’espère que ça aide.
Answer:
Yes
Step-by-step explanation:
There is no unclosable gap. 7+1>7. 7+7>1. An isosceles triangle would be formed.
Answer:
4°
Step-by-step explanation:
Since it is said that the angles are corresponding angles so we know that corresponding angles are equal then,
<1 = <2
3x - 7 ° = x - 1°
3x - x = 7° - 1°
2x = 8°
x = 8° / 2
Therefore x = 4°
Hope it will help you :)
