Rewrite the system of equations in matrix form.

\begin{bmatrix}1&2&-2\\3&7&-1\\2&4&m\end{bmatrix} \mathbf x = \mathbf b

This system has a unique solution \mathbf x = \mathbf A^{-1}\mathbf b so long as the inverse of the coefficient matrix \mathbf A exists. This is the case if the determinant is not zero.

We have

\det(\mathbf A) = m+4

so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.

A geologist visits 40 volcanoes in Alaska and California. 15% of the volcanoes are in California.
kotegsom [21]

Answer:

<h2>Most explained:</h2>

40% = 100%

15 = (100% - 15% = 85%) 85% in Alaska

California = 15% of 40 = (0.15 x 40) = 6

Alaska = 85% of 40 = (0.85 x 40) = 34

<h2>The simple way (or the way i found it simple):</h2>

<h3>40 - 15 = 34</h3><h3>15% of 40 = 6</h3>

<h3>(I found the simple way after i solve the first way)</h3>

Bye, i hope this helps.

Describe the relationship between GF and CD when the two lines are perpendicular to AB. Also describe the relationship between G
Tamiku [17]

Answer:

congruent

Step-by-step explanation:

If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. When two adjacent angles form a linear pair, their non-shared sides form a straight line (m).

i'm not sure tho

Use the figure below to identify angles and segment lengths
slega [8]

So Angle GEN and FED are vertical angles, which means that their angles are congruent. Therefore, Angle FED is 60°

Angle GEN and DEN are a linear pair, which means that they are supplementary angles (add up to 180). To find Angle DEN, we have to form the equation: 60 + DEN = 180

For this, all you have to do is subtract 60 on both sides, and your answer will be: DEN = 120°
