Answer:
5/6-2/3=1/6
Step-by-step explanation:
You make the denominators the same. Like 5/6 and 2/3 you can make the fractions have the same denominator.
5/6-2/3 is the same as the equation 5/6-4/6 but simplified.
We can focus on each part separately, first the numbers:
-3 times (5 squared)
-3 times 25
= -75
This rules out the last two options
Next let’s focus on the x terms:
x^3 times (x^5 squared)
When raising a term that is already raised to a power by another power, you multiply the powers, in this case 5 times 2 = 10
x^3 times x^10
When multiplying numbers with the same base, you add the powers
=x^13
So the answer must be B but we can check the y terms just to make sure
y^2 times (y^4 squared)
y^2 times y^8
=y^10 which matches answer B
Answer:
Parallel= y-5x-3
perpendicular=y=5x

Answer:
This is an example of placebo testing.
Step-by-step explanation:
This is an example of placebo testing in which, the two groups are given two substances that are said to have an effect on the condition that is being treated but one of them is the actual medicine that is being tested while the other one has no real effect over the medical condition. But the volunteers are not given information on which of the medicines is real and which is not, so that this does not affect the outcome of the experiment.
I hope this answer helps.
