Answer:
<em><u>Multiplicative identity property:</u></em> 1 A = A 1A=A 1A=A
This property says that when you multiply any matrix A by the scalar 1, the result is simply the original matrix A.
Answer:
For line j to be parallel to line k, then x has to be equal to 0
Step-by-step explanation:
if line j is parallel to line k, then the two angles are equal.
They are equal because they would be alternate angles and alternate angles are equal in value
Thus,
3x + 10 = 5x + 10
5x-3x = 10-10
2x = 0
x = 0
