We are told that circle C has center (-4, 6) and a radius of 2.
We are told that circle D has center (6, -2) and a radius of 4.
If we move circle C's center ten units to the right and eight units down, the new center would be at (-4 + 10), (6 - 8) = (6, -2). So step 1 in the informal proof checks out - the centers are the same (which is the definition of concentric) and the shifts are right.
Let's look at our circles. Circle C has a radius of 2 and is inside circle D, whose radius is 4. Between Circle C and Circle D, the radii have a 1:2 ratio, as seen below:
If we dilate circle C by a factor of 2, it means we are expanding it and doubling it. Our circle has that 1:2 ratio, and doubling both sides gives us 2:4. The second step checks out.
Translated objects (or those that you shift) can be congruent, and dilated objects are used with similarity (where you stretch and squeeze). The third step checks out.
Thus, the argument is correct and the last choice is best.
1.1x+1.2x-5.4=-10x
Move all terms to the left:
1.1x+1.2x-5.4-(-10x)=0
Add all the numbers together, and all the variables
2.3x-(-10x)-5.4=0
Get rid of parentheses
2.3x+10x-5.4=0
Add all the numbers together, and all the variables
12.3x-5.4=0
Move all terms containing x to the left, all other terms to the right
12.3x=5.4
x=5.4/12.3
x=3.8571428571429/8.7857142857143

after watching a two minute video on how to tell if a relation is a function, I can confidently tell you that the answers are 2, 3, & 4.
<h3>
step-by-step explanation</h3><h3>
</h3>
answers 3 & 4 are the x and y coordinates of the points.
this relation is not a function because it does not pass the vertical line test.
( the vertical line test is where you look at all the vertical lines on the page and check if any of them have multiple dots on them. in this case, the line at x coordinate 1 has dots on both (1, 1) and (1, -1) )
Answer:
10+8+6=24 the ratio of taking the biographies to the science books are: 4:3
Step-by-step explanation:
That is the answer because 10+8+6= total 24 books
ratio of biographies= 24:8=3:1
ratio of science fiction= 24:6= 4:1
hence according axiom 1 ab × Ac= aa × BC
3:1×4:1= 4:3
HOPE THIS HELPSBYOU✌️
The answers is the last one
