Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
A translation 2 units to the left followed by dilation by 1/2.
The correct option is (B).
<h3>What is congruency?</h3>
It states that that two triangles are said to be congruent if they are copies of each other and when superposed, they cover each other exactly.
The complete question is:
Which of the following composition of transformations would create an
image that is not congruent to its original image?
A rotation of 45° followed by a reflection across the x-axis
A translation 2 units to the left followed by dilation by 1/2
A reflection across the y-axis followed by a rotation of 60°
A rotation of 135º followed by a translation of 4 units to the right.
After a translation of 2 units to the left followed by dilation by 1/2 the image will not be congruent to its original image.
All other options are reflection and rotation, which not fit into the situation.

Answer:
Below
Step-by-step explanation:
First we combine your first set of terms,
7b^2 + 2b^2 = 9b^2
There's a subtraction hidden in there!
9b^2 - 3b^2 = 6b^2
Next we do the same thing for the second term,
3b + 7b = 10b
but there's a subtraction in the expression!
10b - b = 9b
Then we finish with our third term
6 + 5 = 11
Answer:
6b^2 + 9b + 11
I think the problem is
2X+20=400
You just have to answer I think X and X equals that two numbers I’m not 100% sure but I’m trying to help
