Given the statement:

WITCHER [35]

D. Intersection is a point.

C doesn’t explain the point, B and A mean the same thing and they don’t make sense because not all points are intersections, but all intersections are points, so your answer is D.

Using Cramer’s Rule, what is the value of x in the system of linear equations below?

MArishka [77]

We have to solve the system of equations by Cramer's rule.

The coefficient matrix is given by

$D=\begin{bmatrix}3&4\\8 &-2\end{bmatrix}$

Let us find the determinant of coefficient matrix.

$|D|= -6-32=-38$

For X-matrix

$D_x=\begin{bmatrix}15&4\\40 & -2\end{bmatrix}$

Now, we find its determinant

$|D_x|=-30-160=-190$

For Y-matrix

$D_x=\begin{bmatrix}15&3\\ 40&8\end{bmatrix}$

Now, we find its determinant

$|D_y|=120-120=0$

Therefore, the value for x is given by

$x=\frac{D_x}{D}\\\\x=\frac{-190}{-38}\\\\x=5$

The value for x is 5.
