Answer:

Solution of an Equation in Two Variables - Generally, a two-variable system solution is an ordered pair that makes BOTH equations valid.

Graph of an Equation in Two Variables - In the Ax + By = C form, linear equations with two variables will appear, and the resulting graph is always a straight line.

Linear Equation - Any equation that can be written in shape is a linear equation. Ax+b=0, 0.0 Where the real numbers are a and b, and x is a vector.

Linear Function - Those whose graph is a straight line are linear functions. The following form has a linear function. F(x) = y = a + bx.

N + M? N = 9.1 7.9 -2.4 0.2 -5.8 1.4 and M= 8.2 -0.6 -2.8 -1.8 -2.4 -6.1

Ierofanga [76]

Answer:

$N + M = \begin{pmatrix}17.3&7.3\\ -5.2&-1.6\\ -8.2&-4.7\end{pmatrix}$

Step-by-step explanation:

$\begin{pmatrix}9.1&7.9\\ -2.4&0.2\\ -5.8&1.4\end{pmatrix} +\begin{pmatrix}8.2&-0.6\\ -2.8&-1.8\\ -2.4&-6.1\end{pmatrix} =\begin{pmatrix}9.1+8.2&7.9-0.6\\ -2.4-2.8&0.2-1.8\\ -5.8-2.4&1.4-6.1\end{pmatrix}$

Then

$\begin{pmatrix}9.1&7.9\\ -2.4&0.2\\ -5.8&1.4\end{pmatrix} +\begin{pmatrix}8.2&-0.6\\ -2.8&-1.8\\ -2.4&-6.1\end{pmatrix} =\begin{pmatrix}17.3&7.3\\ -5.2&-1.6\\ -8.2&-4.7\end{pmatrix}$

What is the distance BC between the two horizontal parallel bars?

pochemuha

One thing you should notice is that the transverse line and the parallel line form a right triangle. We are told that the base is 4 and the angle between the hypotenuse and the leg is 45°

From this we can solve for the second leg. Here's the list of trig functions

sinФ = opposite/hypotenuse
cosФ = adjacent/hypotenuse
tanФ = opposite/adjacent

Since we are only given the adjacent and we are trying to solve for the opposite leg, we can deduce we use tanФ. So we get

$tan45 = x/4$

Multiply by 4 to isolate x and we get

$4*tan45$ = x
Hopes this helps!
