Answer:#2 Experimental
Step-by-step explanation:
In an observational study, we measure or survey members of a sample without trying to affect them.
In a controlled experiment, we assign people or things to groups and apply some treatment to one of the groups, while the other group does not receive the treatment.
so you were earning say "x", so "x" is the 100% of your paycheck.
but you're da bomb and so you got a raise of 5%, so the new amount of your paycheck is 100% + 5%, so is 105% really, and we happen to know that is $100.
Answer:
x= 8,-18
Step-by-step explanation:

The answer is D. -3
you subtract x2 for x1 over y2 for y1 then you'll get 15/-3 then simplify the fraction
