Answer:
(a) Output = 37
(b) Input = 9
Step-by-step explanation:
Given

Solving (a): Output, when input = 8
This means that, we solve for y when x = 8
So, we have:




Solving (b): Input, when output = 42
This means that, we solve for x when y = 42
So, we have:


Collect like terms


Divide both sides by 5

Hello there! So the speed goes up in 6 seconds, maintains for 8 seconds, and then holds for 20 seconds. When something is resting, the line stays straight horizontally for that 20 seconds. B and C are eliminated, because there is no break for C and B does not show the speed accurately. Really, the fish would speed up to 2.5 m/s in 6 seconds, then it maintains that speed, and slows down. D shows a constant speed, which the speed isn't constant, so D is out. A is the only one that represents the scenario properly. The answer is A.
Answer:
the mode would be 24
Step-by-step explanation:
it is what numbers appears most often
A+b+8 = 11-3c
a+b+3c = 11-8
a+b+3c = 3
a = b-1
c = b+1
b-1+b+3*(b+1) = 3
2b-b+3b+3 = 3
4b = 3-3
4b = 0
b = 0
a = b-1
a = 0-1
a = -1
c = b+1
c = 0+1
c = 1
a = -1, b = 0, c = 1
