First you subtract 8x to both sides so you get
2y=-8x+ 70
then you divide 2 with everything to get y by itself
-4x+35=y
The correct answer would be : Slope : 3/2 and Y-Intercept : −3
I hope that this helps you !
The percentage of the radioactive isotope left is 25.0000%.
<h3>What is the half life?</h3>
The half life of a radioactive isotope is the time that will elapse before only half of the number of original isotopes will remain.
Now;
We are told that;
Half life (t1/2) = 55 days
Time taken (t) = 115 days
Ratio of isotope remaining = N/No
Thus;
N/No = (1/2)^t/t1/2
N/No = (1/2)^115/55
N/No = (1/2)^2
N/No =1/4
Hence, the percentage = 1/4 * 100/1 = 25.0000%

Answer:
4√6
Step-by-step explanation:
For right now, I will assume that the "<em>Follow my new brainly at..</em>" part is irrelevant.
Anyways, to find the square root of a number, usually the best way is to find its prime factorization first:
96 : 
We can rewrite that as:
Simplify!
Since is the same thing as 
, that is our answer.
Thusly, as seen above, the answer is 
.
Hope this helps! ((;
