By radical do you mean the square root symbol?
I believe it is 1, but i'm not completely sure.
Answer:
-3, -4, -4, 0, 16, 64, 192.
Step-by-step explanation:
I don't know for sure if this is correct, but when i did it theses are the answers i got. You do y=8*2^x. Meaning you substitute the x for the x values such as -3, -2, and -1.
Also if you have one there's a setting you can go to on an actual calculator and type in this on a Y/X chart. I didn't use one this time because i don't have one, but thought you'd find that information useful.
6x-18
you pretty much h just multiply both the first part of the parentheses by the number outside, then the second :)
Since, the co-interior angles(55° and 125°) are supplementary(sum is 180), therefore the lines are parallel.
