Rewrite the system of equations in matrix form.
This system has a unique solution so long as the inverse of the coefficient matrix exists. This is the case if the determinant is not zero.
We have
so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.
Answer:
7.89474% decrease
Step-by-step explanation:
Solution:
Calculate percentage change
from V1 = 38 to V2 = 35
(V2−V1)|V1|×100
=(35−38)|38|×100
=−338×100
=−0.0789474×100
=−7.89474%change
=7.89474%decrease
Answer:
4t³-5t²+2t+200 - (3t³-2t²+5t+100) = t³-3t³-3t+100
Step-by-step explanation:
-7x^2 - 6x^2 + 3x + 5x - 5 + 2
-13x^2 + 8x - 3
105 is the product of 15 and 7.
