He pays 119.93$ but including tax he pays 128.92$ With the tax being 8.99$
This is a way to work it out
Answer:
The image of
is ![(2,12)](https://tex.z-dn.net/?f=%282%2C12%29)
Step-by-step explanation:
First you need to find the translation vector.
Let the translation vector be
. Then the translation rule is
.
From the equation, the image of
is
.When we apply this rule using the translation vector, we get
![P(2,-4)\to P'(2+a,-4+b)](https://tex.z-dn.net/?f=P%282%2C-4%29%5Cto%20P%27%282%2Ba%2C-4%2Bb%29)
Now we have
![P'(2+a,-4+b)=P'(-3,6)](https://tex.z-dn.net/?f=P%27%282%2Ba%2C-4%2Bb%29%3DP%27%28-3%2C6%29)
We can therefore equate corresponding coordinates
and ![-4+b=6](https://tex.z-dn.net/?f=-4%2Bb%3D6)
This implies that:
and ![b=6+4](https://tex.z-dn.net/?f=b%3D6%2B4)
and ![b=10](https://tex.z-dn.net/?f=b%3D10)
Hence our translation vector is ![u=(-5,10)](https://tex.z-dn.net/?f=u%3D%28-5%2C10%29)
The translation rule now becomes:
.
To find the image of (7,2), we plug it into the translation rule.

Answer:
The answer in the simplest form would be 28/9 or 3 1/9
Step-by-step explanation:
Very simple you would divide the 56 and the 18 by 2 and you get 28/9.
or you could change it to a improper fraction in that case it would be 3 1/9
6x-20
because you do....2 times 3x.....wich equals 6x......
next you take 2 times 10 wich equals.....20......
so it is 6x-20
