Alright, lets get started.
Justin is asked to solve the linear equations using elimination method.
By using elimination method means we have to multiply some numbers in our given equations in such a way that the co-efficient of x or y become same in both equations so that we could add or subtract them to cancel one of the term either x or y.
So, given equations are :
See we have 5x in first equation and -20x in second equation.
So, we try to change 5x into 20 x by multiplying it with 4, both of the equations will have 20 x in common
Lets multiply 4 in first equation
Now both equations could be added and 20 x will be cancelled out and we could easily find the value of y then solve for x.
So, Justin should try to change 5 so that it will be cancels, so option B : Answer
Hope it will help :)
Answer:
try (-4,6)
Step-by-step explanation:
if you use tracing paper, put a mark where the point is
put the tip of the pencil on the point which it will rotate around
spin the paper by the degrees
see where the traced point ends up

Answer:
They include;
1. Fewer chances of determining how effective the treatment plan would be.
2. Inability of every patient to access the experimental treatment.
3. Difficulties in making knowledgeable decisions on the treatment plan.
4. Determining that the experimental treatments are offered with the right motive.
Step-by-step explanation:
In medical treatment administration, it is standard practice that drugs undergo clinical trials on test animals before they are administered to patients. However, some sicknesses are without known drugs for treatment or may have drugs that are still undergoing experiments and trials. In such cases, patients may want to be treated with experimental drugs.
Ethical issues such as the above-listed can arise from this. The foremost of them all is the fact that the treatment might prove ineffective thus causing more problems to the patient.
