Please help me<br> This is analytic geometry
Vlada [557]

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)

Solve quadratic formulax^2-4x+3=0
bekas [8.4K]

The general formula for a equation of the form:

ax^2+bx+c=0

is:

x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:

\begin{gathered} x=\frac{-(-4)\pm\sqrt[]{(-4)^2-4(1)(3)}}{2(1)} \\ =\frac{4\pm\sqrt[]{16-12}}{2} \\ =\frac{4\pm\sqrt[]{4}}{2} \\ =\frac{4\pm2}{2} \end{gathered}

then:

x_1=\frac{4+2}{2}=\frac{6}{2}=3

and

x_2=\frac{4-2}{2}=\frac{2}{2}=1

Therefore, x=3 or x=1.
