If <span>a ≥ 0</span><span> then </span><span>√a</span><span> denotes the non negative square root of </span>a<span>.
</span><span>(x-9)^2 = (-(x-9))^2
</span>
So both <span>x−9</span><span> and </span><span>−<span>(x−9)</span></span><span> are square roots of </span><span><span>(x−9)</span>2</span><span>, but we want to pick whichever is non negative.
</span><span><span>
x−9</span>|</span><span> does that for us.
</span>
Answer should be √<span>(x-9)^2) = x-9</span>
Answer:
I think there's 502
Step-by-step explanation:
if this is a olunomical question that should be it I believe, because you have to write in standered form then when it equals zero, then factor it
1/5
1/3
8/100
Three fractions that are less than 40%.
Look at the table for the people that used Lithium.
There are 18 relapses, 6 No relapses with a total of 24 people.
The relative frequency for relapse, would be dividing the number of relapses by the total number of people.
This would be D. 18 / 24 = 75%
