Answer:
5>t
Step-by-step explanation:
45 > 12t + 3(t -8) - 6 multiply 3 times t-8
1) 45 > 12t + 3t - 2 - 6 combine alike terms
2) 45 > 15t - 30 isolate the variable by adding 30
3) 75 > 15t divide by 15
4) 5 > t
Lol I don’t know if this is the one luv but here
P represents the population in millions.
An exponential function with a positive exponent means function increases with time t.
An exponential function with a negative exponent means function decreases with time t.
So we're looking for a function with a NEGATIVE exponent.
Also, since question says population will remain CONSTANT at the minimum of 2 (millions) insects, so it should not be a function of time t.
Therefore this condition should be written as P>=2 (millions) [and not 2t].
Given the above information, it will be up to you to choose the correct answer choice.
T>-31/5
Step 1: (2•(t+5)) - (4t - 7 • (t+3)) >0
Step 2: 2• (t+5) - (-3t - 21) > 0
Step 3: 5t + 31 > 0
Step 4: Divide both sides by 5
t+(31/5) >0
