Answer: D' is (-8,4)

Step-by-step explanation: The rule for reflection y=x is (x,y)>( y,x) So when  relecting over the axis y=x the x cordinate and the y cordinate switch places.

Answer:

Every morning, I get up and wash my face. Then I sit at my desk and I write. It can be anything. To your future self who will hopefully never read it, a letter to someone you like or don't like regardless of whether you give it to them. Maybe write about what you're feeling in the moments between waking up and sitting down. Don't stop writing until you've emptied your head and put it all on paper.

I don't remember where I learned this but it was called Morning Pages. Some call it Mourning Pages because you're saying goodbye to yesterday and looking forward to the day coming.

Was that what you were looking for??? Or???

The third term of a sequence is 120. The fifth term is 76.8. Write an explicit rule representing this geometric sequence.
juin [17]
The nth term of the geometric sequence is:
an=ar^(n-1)
where 
a=first term
r=common ratio
n=nth term
from the question:
120=ar(3-1)
120=ar^2
a=120/(r^2)....i
also:
76.8=ar^(5-1)
76.8=ar^4
a=76.8/r^4.....i
thus from i and ii
120/r^2=76.8/r^4
from above we can have:
120=76.8/r²
120r²=76.8
r²=76.8/120
r²=0.64
r=√0.64
r=0.8
hence:
a=120/(0.64)=187.5
therefore the formula for the series will be:
an=187.5r^0.8
