Answer:
From the said lesson, the difficulty that I have been trough in dealing over the exponential expressions is the confusion that frequently occurs across my system whenever there's a thing that I haven't fully understand. It's not that I did not actually understand what the topic was, but it is just somewhat confusing and such. Also, upon working with exponential expressions — indeed, I have to remember the rules that pertain to dealing with exponents and frequently, I will just found myself unconsciously forgetting what those rule were — rules which is a big deal or a big thing in the said lesson because it is obviously necessary/needed over that matter. Surely, it is also a big help for me to deal with exponential expressions since it's so much necessary — it's so much necessary but I keep fogetting it.. hence, that's why I call it a difficulty. That's what my difficulty. And in order to overcome that difficulty, I will do my best to remember and understand well the said rules as soon as possible.

can 4.5 be rounded up to 4? nope.
1. The number '3' is located in the tens place
2. Since the number '7' is located in the ones place, it's telling the number '3' to go up
Stays the Same; 1,2,3,4
Goes Up: 5,6,7,8,etc
837 ⇒ 840
$3.49 X .10 = .35
the discount is .35 or 35 cents
final cost
3.49-.35= $3.14
hope this helps
Answer:
The new coordinates are (-11, -35)
Step-by-step explanation:
When reflecting across the x-axis, you are just the Y. value. It is the opposite due to the fact that if you're moving something across the horizontal x-axis, it's actually the vertical height changing. So, you just inverse the Y value to its' negative or positive reciprocal.
