XY is a translation of XY.

Mathematics
1 answer:
seropon [69]3 years ago
3 0

Given:

The graph of a translation. X'Y' is a translation of XY.

To find:

The rule of the translation.

Solution:

Let the rule of the translation be

(x,y)\to (x+a,y+b)            ...(i)

So, we need to find the value of a and b.

From the given graph, it is clear that X(-4,-9) and X'(-1,0).

Using (i), the image of X(-4,-9) is

X(-4,-9)\to X'(-4+a,-9+b)

We have, X'(-1,0). So,

X'(-4+a,-9+b)=X'(-1,0)

On comparing both sides, we get

-4+a=-1

a=-1+4

a=3

And,

-9+b=0

b=9

So, the missing values in the rule of the translation are 3 and 9 respectively.

Therefore, the rule of translation is (x,y)\to (x+3,y+9).

If 5 dozen roses can be purchased for $62.50, how much will 8 dozen cost?
lesya692 [45]

Source: Net

Let x represent the cost of a dozen roses. 5 dozen roses can be purchased for $62.50 . Consider the following equation. 5x = $62.50. Here the product and factor are known, thus divide by the factor on both sides of the equation.

5x   $62.50

--  =     --

5     $12.50

Now to find out the cost of 8 dozens multiply the value of x by 8.

8x=8 ($12.50) = $100

Answer would be $100.
