Answer:
Determinant are special number that can only be defined for square matrices.
Step-by-step explanation:
Determinant are particularly important for analysis. The inverse of a matrix exist, if the determinant is not equal to zero.
How to find determinant
For a 2×2 matrix
For a 3×3 matrix
we first decompose it to 2×2
Example
Find the values of λ for which the determinant is zero
Equating the determinant to zero
s = * (1 ±5 )
s = 1.61 or -0.61
Answer:
Step-by-step explanation:
Given the following question:
In order to find the answer, we will solve the inequality as if it is a regular two-step equation and then we will plot the answer on the number line.
<u>When plotting inequalities on the number line keep a few things in mind:
</u>
. 4 is greater than x, so the line will go towards the opposite direction of four
. < is a greater sign, it's not a greater or equal to sign (≤) which means it will be an open dot.
Hope this helps.
