The matrix that best represents the linear system of equations must be written vector by vector in each of the rows. That is, components x in column 1, components and in column 2 and component z in column 3. In column 4 you write the results. Attached solution.
Slope intercept form is y =mx+b. To find your slope since you already know the y-intercept you how to subtract y2-y1 over x2-x1. That is -6-(3) over -2-(-5) but for -2-(-5) you have to keep change change and you'll get 3. then find what -6-(3) is and you have your slope, so just plug it into the equation.
First you need to find out how much he spends on each session.
0.15 is the answer.
Answer:
<h2>n = -12</h2>
Step-by-step explanation:
2n + 5 = n - 7 <em>subtract 5 from both sides</em>
2n + 5 - 5 = n - 7 - 5
2n = n - 12 <em>subtract n from both sides</em>
2n - n = n - n - 12
n = -12
By <em>trigonometric</em> functions we find that the measure of angle A is approximately 0.12π radians.
<h3>How to determine the missing angle in a right triangle</h3>
In this question we have a <em>right</em> triangle, of which the length of two sides are known (AB, BC). We can know the measure of angle A by <em>trigonometric</em> functions:


A ≈ 0.12π radians
