![T^{-2}:(x,y)](https://tex.z-dn.net/?f=T%5E%7B-2%7D%3A%28x%2Cy%29)
means doing the inverse transformation twice.
The forward transformation is given as
![T:(x+3,y+1)](https://tex.z-dn.net/?f=T%3A%28x%2B3%2Cy%2B1%29)
so the inverse transformation is
![T^{-1}:(x-3,y-1)](https://tex.z-dn.net/?f=T%5E%7B-1%7D%3A%28x-3%2Cy-1%29)
and
By solving a linear equation we will see that the value of x is 10.

</h3><h3>How to find the value of x?</h3>
Remember that for any triangle, the sum of all internal angles is always equal to 180°.
Here only look at triangle BCD, we know that:
m∠DBC = m∠ABC = 3x
m∠BCD = m∠ACB + m∠ABD = 2x + 65°
m∠ADC = 65°
Now we can write the linear equation as:
3x + 2x + 65° + 65° = 180°
5x + 130° = 180°
5x = 180° - 130°
5x = 50°
x = 50°/5 = 10°
The value of x is 10.

Answer:
$6.60
Step-by-step explanation:
12% = 0.12
12% of $55 = 0.12 x 55
=6.6
So, $6.60
7b-6(11-2b)=10
The first step is to distribute. Multiply each number inside the parentheses by -6.
7b + (-6*11) + (-6*-2b) = 10
7b - 66 + 12b = 10
Now combine like terms.
19b - 66 = 10
Add 66 to both sides.
19b = 76
Divide both sides by 19.
b = 4
The answer is b = 4.
