A bookkeeper bought 2,000 exercise book distributed 200 books to the student from poor economic background as donation .he sold
Andrews [41]

Books left=2000-200=1800

ATQ

\\ \sf\longmapsto 1800x+10=0.08x

\\ \sf\longmapsto 1800x-0.08x=-10

\\ \sf\longmapsto x(1800-0.08)=-10

\\ \sf\longmapsto x(1799.92)=-10

\\ \sf\longmapsto x=|\dfrac{10}{1799.92}|

\\ \sf\longmapsto x=0.005

Now

\\ \sf\longmapsto CP=0.005(2000)=10

Which type of transformation is described by (x, y)<br> -&gt;<br> + (x + 3, y — 2)?
creativ13 [48]

Answer:

(x, y) → (x+3, y-2) means Translation 3 units left and 2 units down.

Step-by-step explanation:

Given the rule of transformation:

(x, y) → (x+3, y-2)

If we move horizontally 3 units to the right, 3 is added to the x-coordinate of any given point, and then 2 units down.

In other words,

(x, y) → (x+3, y-2) means Translation 3 units left and 2 units down.

For example,

Let say if we have the point A(4, 5)

Using the translation rule:

(x, y) → (x+3, y-2)

A(4, 5) → A'(4 + 3, 5 - 2) → A'(7, 3)

Therefore, the new position of A(4, 5) after translating 3 units left and 2 units down would be: A'(7, 3)
