2\5 + 2\4
Lcm of 4 and 5 is 20
So 20 divided by 5 is 4 × 2 = 8 and 20 divided by 4 is 5 × 2 = 10
10+ 8 =18\20 = 9\10
Answer:
See below
Step-by-step explanation:
The first one IS decay...as 'x' increases the function decreases
the second and third are NOT ...as 'x' increases the value increases
radioactive decay IS decay (obviously)
the one with e^2x is not ....it grows exponentially as x grows
and finally the last one is decay because as x gets larger the value of y gets smaller
Answer:
I NOT 100% SURE BUT I THINK ITS .B)
Step-by-step explanation:
First divide both sides by 2 so that we can get rid of the parentheses, so we get

now subtract 5 from both sides

then finally we want x alone so we'll divide both sides by 3 and get our final answer!
1. 2^6.
2. 2^3.
3. 3^7
4. 6x^4
5. 4x^2
6. 12n^5
7. 9x^2
To find the answer of these questions, add the exponents. If there is whole numbers in the problem, you have to multiply the numbers. For number 7, do 3^2 and x^2. Hope this helps!
