The temperature decreased by 5 degrees per hour, as -25 / 5 is -5.
Answer:
15 years
Step-by-step explanation:
93400=65000*e^(.025x)
x=14.5 which rounds to 15
Answer:
5 and 11
Step-by-step explanation:
Make equations:
x+y = 16
3x-4 = y
Substitute 3x-4 as y in x+y = 16
You get x + 3x - 4 = 16
Simplify into 4x - 4 = 16
Add 4 on both sides
you get 4x = 20
Divide each side by 4,
You get x = 5. Plug 5 back into x+y = 16
Subtract 5 from both sides, and you get y = 11
The smallest root is -5. The other is 3.
You can get these by factoring. The easiest way to do so is by pulling out a 4 first and then using your normal factoring patterns.
