Thank you for coming to Brainly with your questions!
I believe the answer is:
30x + 80y - 15z. The question tells us that she earns 30 points for each fish, and since we do not know how many, we just write 30x, then we add 80 points for each octopus, so that's + 80y, and then subtract 15 points for each time she captures a crab, so - 15z.
I hope this helps you! Please mark Brainliest! Let me know if I can help you with any further questions!

Answer:
1 / x^8
Step-by-step explanation:
We know that a^b / a^c = a^ (b-c)
x^7 / x^ 15 = x^ (7-15) = x^-8
We also that that a^-b = 1/ a^b
x^-8 = 1 / x^8
Answer:
1) The original price is 8920 2) The mark up is 580
Step-by-step explanation:
!)We need to find out the initial price, suppose it is equal to 100 percents. The price was raised and it has reached 100+6.5= 106.5 percents . 106.5 percents from initial price is the new price (RM 9500). Find out the value of one percent
9500:106.5= 89.2 (approximately).
2)Then find the original price multiplying the value of percent by 100. 89.2*100= 8920 - initial price
3)Then mark up is a remainder between old price and new price . It is 9500-8920= 580.

Answer: f(x) = (-1/2)x+1, choice B</h3>
=================================================
Explanation:
The diagonal line passes through 1 on the vertical y axis. So the y intercept is b = 1. This means the location of the y intercept is (0,1).
Start at (0,1) and move down 1 and to the right 2 to arrive at (2,0). This is another point on the diagonal line. The motion of "down 1 and right 2" is effectively the slope
slope = rise/run = -1/2
rise = -1, run = 2
The rise being negative means we have gone downhill as we move to the right.
With m = -1/2 as the slope and b = 1 as the y intercept, we go from y = mx+b to y = (-1/2)x+1
The last thing to do is replace y with f(x) to get f(x) = (-1/2)x+1 as the final answer.
