Answer:
- 240
Step-by-step explanation:
We have to find the value of the following determinant

Now, we know that the value of a general determinant
is given by [a( ei - fh) + b(fg - di) + c(dh - eg)]
Therefore, the value of the given determinant is
= 4[0 × 4 - (-1)(-2)] + 8[3(-1) - 4 × 4] + 10[4(-2) - 3 × 0]
= - 8 - 152 - 80 = - 240 (Answer)
Answer:
y= (C - Az)/B
Step-by-step explanation:
Az +By = C
Az - Az + By = C - Az
By = C - Az
Divide both side by the coefficient of y which is B
therefore we have:
y = (C - Az)/B
Answer:
the answer is c
