Answer:
a) during the 3rd season the populations will be the same
b) after 11 1/4 seasons the second species of fish will be eliminated
Step-by-step explanation:
1) y = 25x + 255
2) y = -40x + 450
the above linear equations model the statements from the problem
we can find out when the two populations will have the same amount by graphing them and finding the point of intersection or by setting them equal to each other:
25x + 255 = -40x + 450
add 40x to each side to get:
65x + 255 = 450
subtract 255 from each side to get:
65x = 195
x = 195/65
x = 3
To find the season when the second species is eliminated we can use the second equation and set 'y' equal to zero and solve for 'x':
0 = -40x + 450
subtract 450 from each side to get:
-450 = -40x
x = -450/-40
x = 11.25
Answer:
True
Step-by-step explanation:
It is true because the solutions are x = -4, -3, and 3.
I graphed the equations on the graph below.
If this answer is correct, please make me Brainliest!
240(v+2.5)=1300-240v
240v+600=1300-240v
480v=1900
v=95/24
v-2.5=v-5/2
95/24-60/24=35/24
So the faster group travels at 95/24 mph (≈3.96 mph) and the slower group travels at 35/24 mph (≈1.46mph)
check...
240(95/24)=950 miles from the origin...
1300-240(35/24)=950 miles from the origin...
Answer:
26,400 feet is 5 miles, so 5,280 fph.
Step-by-step explanation:
1 foot is equal to 0.000164 mile.
