Solve by elimination -2x - 6y = 0 3x +11y=4

1 answer:

5 0

Work

-2x - 6y = 0
3x + 11y = 4

Either y or x must be a negative.

If x is -6, and y is 2 then
(-2 · -6) - (6 · 2) = 0
12 - 12
and
(3 · -6) + (11 · 2) = 4
-18 + 22

Answer

x = -6
y = 2

For what value(s) of k is the linear system consistent? (Enter your answers as a comma-separated list.)

AleksAgata [21]

Answer:

Step-by-step explanation:

Given

$6x_1-9x_2=8$

$9x_1+kx_2=-1$

The given system is $AX=B$ can be represented by

$\begin{bmatrix}6 &-9 \\ 9 & k\end{bmatrix}\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}8\\ -1\end{bmatrix}$

The given system is consistent when determinant of A is not equal to zero

$|A|$

$|A|=6k-(-81)=6k+81$

$k\neq \frac{-27}{2}$

i.e. system is consistent for all value of k except $k=\frac{-27}{2}$

$R-\frac{-27}{2}$
