Step-by-step explanation:
<u>Step 1: Define</u>
10 - 4x ≤ 50
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 10 on both sides: -4x ≤ 40
- Divide -4 on both sides: x ≥ -10
Here we see that any value <em>x</em> greater than or equal to -10 would be a solution to the inequality.
Answer:
146.41
Step-by-step explanation:
third order determinant = determinant of 3×3 matrix A
given ∣A∣=11
det (cofactor matrix of A) =set (transpare of cofactor amtrix of A) (transpare does not change the det)
=det(adjacent of A)
{det (cofactor matrix of A)} ^2 = {det (adjacent of A)}
^2
(Using for an n×n det (cofactor matrix of A)=det (A)^n−1
)
we get
det (cofactor matrix of A)^2 = {det(A) ^3−1
}^2
=(11)^2×2 = 11^4
=146.41
