Answer:
No solution.
Step-by-step explanation:
Eliminate the equal sides of each equation and combine.
-4x-5=-4+5
Solve -4x-5=-4x+5 for x by moving all terms containing x to the left side of the equation. Add 4x to both sides of the equation.
-4x-5+4x=5
Combine the opposite terms in -4x-5+4x.
Add -4x and 4x.
0-5=5
Subtract 5 from 0.
-5=5
Since -5=5, there are no solutions.
The answer is length times width, the answer is 45 times 5 and that's 225
We write the generic exponential equation:
y = A (b) ^ t
Where,
A: initial population
B: growth rate
t: time in hours.
Substituting values we have:
y = 5 (2) ^ ((1 / 1.5) * t)
For t = 9 hours we have:
y = 5 (2) ^ ((1 / 1.5) * 9)
y = 320 million
For t = 24 hours (one day) we have:
y = 5 (2) ^ ((1 / 1.5) * 24)
y = 327680 million
For t = 2 hours we have:
y = 5 (2) ^ ((1 / 1.5) * 2)
y = 12.5992105 million
Answer:
a) t hours?
y = 5 (2) ^ ((1 / 1.5) * t)
b) 9 hours?
y = 320 million
c) 1 day?
y = 327680 million
d) 2 hours?
y = 12.5992105 million
