Answer:
522
Step-by-step explanation:
The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:
(all fish)/(number tagged) = (sample size)/(number in sample tagged)
all fish = (number tagged) · (sample size)/(number in sample tagged)
all fish = 174 · 39/13
all fish = 522
If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.

Answer:
D. $25.85
Step-by-step explanation:
470 x 5.5% = 25.85
Step-by-step explanation:
2x+26=2(5-3x)
2x+26=10-6x
combination of like terms
2x+6x=10-26
8x= -16
x= -16/8
x= -2
Answer:
y = 5/2x - 8
Step-by-step explanation:
convert to y = mx + b
2x + 5y = 10
5y = -2x + 10
y = -2/5x + 2
flip the slope to 5/2
y = 5/2x + 2
plug in (2, -3)
-3 = 5/2(2) + b
-3 = 5 + b
-8 = b
y = 5/2x - 8
