Answer:
9 zebra fish and 5 neon tetras. White
Answer:
y = -2x - 3
Step-by-step explanation:
y=mx+b
The slope is already given so m = -2
plug in the point into the equation
y=-1
x=-1
-1 = -2(-1) + b
solve and you get
y = -2x - 3
Step-by-step explanation:
The first number in the sequence is -6.
The second number is -3, which is 1/2 the first number.
The third number is -2, which is 2/3 the second number.
The fourth number is -3/2, which is 3/4 the third number.
The fifth number is -6/5, which is 4/5 the fourth number.
So the pattern is:
![a_{n} = a_{n-1} \frac{n-1}{n}](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%20a_%7Bn-1%7D%20%5Cfrac%7Bn-1%7D%7Bn%7D)
Answer:
y=9sin(theta)
Step-by-step explanation:
I'm assuming it's in degrees. The amplitude of the graph is 9, and so you multiply the base sine equation y=sin(theta) by nine. I don't see any shifts and the period remains at 2pi (360 degrees) so I don't think anything else is really needed.
Answer: 438.4
Explanation: 320 x 37% = 320 x 0.37 = 118.4 so 320 + 118.4 = 438.4
