A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so
A dilation of 2 is the mapping (x'',y'')=(2x', 2y')
So
We can rewrite that without the primes and combine the powers of 2.
Let's graph these and see if we're close,
Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}

ADC should measure to 115 degrees if both measurements are equal to 180 degrees.
If not, ADC might be 25 degrees if both measurements are equal to 90 degrees.
Hope this helps.
Answer: Option B) 7,214
Step-by-step explanation:
The value of the digit 2 in 5,426 is 20.
-In 2,843, the place value of 2 is 2000
- In 7,214, the place value of 2 is 200
- In 43,928, the place value of 2 is 20
- In 67,452, the place value of 2 is 2
So, since he place value of 2 in 7,214 is 200; and since 200 is ten times more than 20 (i.e 20 x 10 = 200)
Thus, the answer is 7214
The answer should be D.
The maximum amount she can add is 7 books and no more, so the first two are wrong. It’s also allowed to be exactly seven, which is why it would be a closed circle.
Hope this helps!
