In this number 800 is 10 times as much as what number. To answer the query we can illustrate this problem into a mathematical equation of 
1. 10 x N = 800 
2. 10N = 800
3. N = 800/10 
4. N = 80

Hence, the number is 80.

Find the preimage of the point (4, 3) under the given transformation. A transformation T : (x, y) (x - 2, y + 3) (2, 6) (2, 3) (

Mashcka [7]

Answer:

The preimage is $(6,0)$

Step-by-step explanation:

The given point is (4,3).

The translation rule is

$T:(x,y)\rightarrow (x-2,y+3)$

Let $(a,b)$ be the preimage.

Then,

We apply this rule to the preimage to obtain;

$T:(a,b)\rightarrow (a-2,b+3)$

This implies that;

$a-2=4$

$\Rightarrow a=4+2$

$\Rightarrow a=6$

Also,

$b+3=3$

$\Rightarrow b=3-3$

$\Rightarrow b=0$

Hence the preimage is $(6,0)$
