Proportional means that if one increases so does the other eg volume of a balloon increases if you heat it - heat is proportional to volume in gases.
Non proportional means that they don't have a similar relationship.

To describe a sequence of transformations that maps triangle ABC onto triangle a"b"c", a student starts with a reflection over t

Paha777 [63]

i dont quite get the question but...

i guess this is how it is.

Take the mirror image of∆ABC Through the a line through the point y=3.

The new ∆ABC would have point C=(4,2)

B=(3,-6) A=(1,-3)

Now shifting the ∆ABC one unit (i.e. 2 acc. to the graph as scale is 1 unit =2) towards right ( or adding 2 to the x coordinates of ∆ABC)

We get the Coordinates of triangle ABC as A=(3,-3) B=(5,-6) C=(6,2).

This coordinate is the same coordinates of ∆A"B"C".

Hope it helps...

How would you find the quadratic that goes through the point (4,0), the axis of symmetry is x=7, and it also goes through the po

Answer:

y = (5/27)(x -7)^2 -5/3

Step-by-step explanation:

Use the given points to find the unknowns in the equation.

If the axis of symmetry is x=7, then the equation can be written in the form ...

y = a(x -7)^2 +b

Filling in the two point values, we have two equations:

0 = a(4 -7)^2 +b ⇒ 9a +b = 0

5 = a(1 -7)^2 +b ⇒ 36a +b = 5

Subtracting the first equation from the second, we have ...

(36a +b) -(9a +b) = (5) -(0)

27a = 5

a = 5/27

Substituting that value into the first equation gives ...

9(5/27) +b = 0

5/3 +b = 0

b = -5/3

So, the quadratic can be written in vertex form as ...

y = (5/27)(x -7)^2 -5/3

Graph the image of kite ABCD after a rotation 180° counterclockwise around the origin.

rewona [7]

Solution:

Given a kite ABCD on a graphhh, with the coordinates given below

$\begin{gathered} A(-8,-6) \\ B(-7,-2) \\ C(-1,-6) \\ D(-7,-10) \end{gathered}$

If the kite is rotated 180° counterclockwise around the origin,

The rule for a rotation 180° counterclockwise around the origin is

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

The coordinates of the kite after the rotation of 180° counterclockwise around the origin will be

$\begin{gathered} A(-8,-6)\rightarrow A^{\prime}(8,6) \\ B^{\prime}(-7,-2)\rightarrow B^{\prime}^(7,2) \\ C(-1,-6)\rightarrow C^{\prime}(1,6) \\ D(-7,-10)\rightarrow D^{\prime}(7,10) \end{gathered}$

The graph is shown below
