See whether you agree with the following statements based upon the diagram:

<span>Vea si está de acuerdo con las siguientes declaraciones basadas en el diagrama:
</span>                                              100 + y
tan 60 = x / y  and  tan 30 = -------------
                                               sqrt(3)

                                            100 + y
Then x = sqrt(3)*y and x = -------------
                                             sqrt(3)
                                                                             100 + y
From these 2 equations we see that sqrt(3)*y = --------------
                                                                             sqrt(3)

                                                                             100 + y
From these 2 equations we see that sqrt(3)*y = --------------
 <span>De estas 2 ecuaciones vemos que                      sqrt(3)
</span>
Then 3y = 100 + y, so that 2y = 100 and y = 50 degrees   (answer)

                                    x                                   x
Again, tan 60 deg = -------    => sqrt(3) = ---------------                                                                            y                                  50

Then 50 sqrt(3) = x (answer)

What is the equation in point-slope form of the line passing through (-1,3) and (1, 7)?
amid [387]

Answer:

<h3>y - 3 = 2(x+1)</h3>

Step-by-step explanation:

The equation of the line in point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is a point on the line

Get the slope;

Given the points (-1,3) and (1, 7)

m = y2-y1/x2-x1

m = 7-3/1+1

m = 4/2

m = 2

Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;

y - y0 = m(x-x0)

y - 3 = 2(x-(-1))

y - 3 = 2(x+1)

Hence the required equation is y - 3 = 2(x+1)
