Vlada [557]3 years ago

Answer:

The coordinates of point B are (-3,-3).

Step-by-step explanation:

Let A(x,y) = (6,-6), C(x,y) = (-6,-2) and \overrightarrow{AB} = \frac{3}{4}\cdot \overrightarrow{AC}, then we have the following formula by vectorial definition of a line segment:

\overrightarrow{AB} = \frac{3}{4}\cdot \overrightarrow{AC}

B(x,y) -A(x,y) = \frac{3}{4}\cdot [C(x,y)-A(x,y)]

B(x,y) = \frac{3}{4}\cdot C(x,y) +\frac{1}{4}\cdot A(x,y)

B(x,y) = \frac{3}{4}\cdot (-6,-2)+\frac{1}{4}\cdot (6,-6)

B(x,y) = (-3, -3)

If a line has slope​ a, what is the slope of its reflection across the line y​=x?
aleksandrvk [35]

Check the picture below.

notice the reflected gray line on the red one over the y=x line, the slope of either line across the y=x line is simply the other's upside-down.

\stackrel{\textit{slope of line "a"}}{a\implies \cfrac{a}{1}}\hspace{5em}\stackrel{\textit{slope of its reflection}}{\cfrac{1}{a}}

F(x)=5/x-1<br> g(x)=4-2x<br> Calculate fg(x)
Leno4ka [110]

Answer:

Step-by-step explanation:

define function fg(x) :

Fg(x)  = f(g(x))

         = \frac{5}{x} (4-2x)-1

         = \frac{20}{x} - \frac{10x}{x} - 1

         = 20 - 10x -1

         = 20 - 1 - 10x

         = 19 - 10x
