Answer:
293.5
Step-by-step explanation:
40×50/2
=1000 cm²
π×15²
3.14×225
706.5
1000-706.5=293.5 cm²
If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.
Answer:
The first one : decay
The second one : growth
When the argument of the exponential expression is bigger that 1 then it represents a growth
When it's less than 1 and above 0 then it's a decay
Answer:
X multiplied by 25 subtract 3
(Sorry this is put in words)
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given the following equation:

You can follow these steps in order to solve for "x" and find its value:
1. Apply Distributive property on the right side of the equation:

2. Subract
from both sides and add the like terms:

3. Subtract 1.8 from both sides:

4. Finally, divide both side of the equation by -1.5:
