Answer: Step-by-step explanation: Line AB is horizontal, so reflection across the x-axis maps it to a horizontal line. Then rotation CCW by 90° maps it ... Which statement accurately explains whether a reflection over the X-axis and a 180° rotation would map figure ACB onto itself?.
90° counterclockwise. Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure ACB onto itself? Which statement accurately explains whether a reflection over the x-axis and a 90° counterclockwise rotation would map figure ACB onto itself? WILL GIVE IF CORRECT, IF WRONG NO Which statement accurately explains whether a reflection over the x-axis and a 90° counterclockwise rotation would map Answer: 9514 1404 393Answer: No, A″C″B″ is located at A″1, 1, C″4 Which statement accurately explains whether a reflection over the x-axis and a 90° counterclockwise rotation would map figure ACB onto itself? a coordinate Take the point (1,0) that's on the x axis. a 90 degree rotation (counterclockwise of course) makes it be on the y axis instead at (0,1). 90 degrees more is ...

Answer:
a= -2/3 b+/35/3 b=
Step-by-step explanation:
For a to find the answer you:
Step 1: Add -2b to both sides.
3a+2b+−2b=35+−2b
3a=−2b+35
Step 2: Divide both sides by 3.
3a

=
−2b+35

For b to find the answer:
3a+2b=35
Step 1: Add -3a to both sides.
3a+2b+−3a=35+−3a
2b=−3a+35
Step 2: Divide both sides by 2.

Answer:
4
Step-by-step explanation:
we have
![f(x)=2(4^x)](https://tex.z-dn.net/?f=f%28x%29%3D2%284%5Ex%29)
This is a exponential growth function of the form
![f(x)=a(1+r)^x](https://tex.z-dn.net/?f=f%28x%29%3Da%281%2Br%29%5Ex)
where
a is the initial value
(1+r) is the base of the exponential function or multiplicative rate of change of the function
r is the rate of change
In this problem we have
![a=2\\(1+r)=4\\r=4-1=3=300\%](https://tex.z-dn.net/?f=a%3D2%5C%5C%281%2Br%29%3D4%5C%5Cr%3D4-1%3D3%3D300%5C%25)
therefore
4 is the base of the exponential function or multiplicative rate of change of the function
![\frac{b}{13}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bb%7D%7B13%7D%20)
-
![\frac{3b}{13}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3b%7D%7B13%7D%20)
=
![\frac{8}{13}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B13%7D%20)
Since the two fractions have a common denominator already, we can just subtract the numerators.
b-3b=-2b or -3b+b=-2b
Either way you get the same answer :)
Our new fraction is
![\frac{-2b}{13}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-2b%7D%7B13%7D%20)
Now we know that this must be equal to
![\frac{8}{13}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B13%7D%20)
Again, since the denominators are already the same of course they are equal. 13=13
Now we have to set the numerators equal
-2b=8
Use inverse operations to get b alone
-2b=8
÷-2 ÷-2
b=-4

Answer:
57 years old
Step-by-step explanation:
- 400 - 3x = 229
- 3x = 171
- x = 57
- 400 - 171 = 229
