5 is an integer but 2/3 is not an integer
2^5 = 32 which is an equivalent expression
I'm not sure if you mean (
) or (
) I solved it both ways .
![f(x) = \sqrt{x + 7} \\ \\ f( \: g(x) \: ) = \sqrt{(8x - 11)+ 7} \\ = \sqrt{8x - 11 + 7} \\ = \sqrt{8x - 4} \\ = 2 \sqrt{2x - 1}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%5Csqrt%7Bx%20%2B%207%7D%20%20%5C%5C%20%20%5C%5C%20f%28%20%5C%3A%20g%28x%29%20%5C%3A%20%29%20%3D%20%20%5Csqrt%7B%288x%20-%2011%29%2B%207%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B8x%20-%2011%20%2B%207%7D%20%20%5C%5C%20%20%20%3D%20%20%5Csqrt%7B8x%20-%204%7D%20%20%5C%5C%20%20%3D%202%20%5Csqrt%7B2x%20-%201%7D%20)

I hope I helped you^_^
Sarah purchased 2 first class tickets, and 5 coach tickets. This is the answer because $2640- $1020-$1020=$600, and $600÷5=$120.
Triangle 1 has vertices at (A, B), (C, D), and (E, F). Triangle 2 has vertices at (A,-B), (C,-D), and (E,-F). What can you concl

Answer:
Triangle 2 is a transformation from Triangle 1, and has been reflected across the x-axis.
Step-by-step explanation:
We can conclude that Triangle 2 is a reflection across the x-axis because the x values stayed the same but the y values are negative.
In a reflection across the x-axis, the x values will stay the same. But, since it is flipped across the x-axis, the y values will become negative.
So, Triangle 2 is a reflection across the x-axis.
