The point A(4, 1) is reflected over the point (0, -3) and its image is point B. What are the coordinates of point B?
omeli [17]

A reflection over the point (0,0) is given by:

(x,y)\rightarrow(-x,-y)

Nevertheless, the reflection is being made over the point (0,-3). We can first make a traslation of the point (0,-3) to the origin. Then, reflect the new coordinates of the point A through the origin and then bring back the new origin to (0,-3).

First, make a traslation such that the new coordinates of (0,-3) are (0,0):

(x,y)\rightarrow(x,y+3)

Then, apply a reflection through the origin:

(x,y+3)\rightarrow(-x,-y-3)

Finally, make a traslation reciprocal to the first one:

(-x,-y-3)\rightarrow(-x,-y-3-3)=(-x,-y-6)

Therefore, the reflection over the point (0,-3) can be written as:

(x,y)\rightarrow(-x,-y-6)

Substitute (x,y)=(4,1) to find out the new coordinates of A after the reflection:

\begin{gathered} A\rightarrow B \\ \Rightarrow(4,1)\rightarrow(-4,-1-6)=(-4,-7) \end{gathered}

Therefore, the coordinates of the point B are (-4,-7).

Match the graph with the correct set of equations for the linear system. Then, classify the system as Consistent and Dependent,
Ivenika [448]

Answer:

Consistent independent

x + y = 0  and  -x + y = -8

Step-by-step explanation:

<u>Inconsistent</u>: parallel lines, no solutions

<u>Consistent dependent</u>: same line, infinite solutions

<u>Consistent independent</u>: intersects at one point, one solution

Therefore, the pair of lines are Consistent independent

From inspection of the diagram:

One line has a negative slope and the other a positive slope.

One has a y-intercept of 0 and the other a y-intercept of -8.

Therefore, the solution is x + y = 0  and  -x + y = -8

Because:

x + y = 0  ⇒  y = -x  (neg slope, y-intercept of 0)

-x + y = -8  ⇒  y = x - 8  (pos slope, y-interecept at -8)

Alborosie

Answer:

-x(x^2 +3x +4)

Step-by-step explanation:

-x^3-3x^2-4x

Factor out a -x

-x(x^2 +3x +4)

We cannot factor inside the parentheses, so this is complete
