is the answer your welcome ^~^
<span>If a matrix is invertible, there are many solutions to Ax=0, I am referring to both homogeneous and non-homogeneous types.</span>
Answer: a = 2.8
Step-by-step explanation:
3/4 (8a + 12) = 25.8
(3/4 * 8a) + (3/4 * 12) = 25.8
6a + 9 = 25.8
6a = 16.8
a = 2.8
Hope this helped! :)
