Answer:

Step-by-step explanation:
Given

Required
Express as scientific notation
The rule of scientific notation is that:
It is represented in form of:
where 
will be represented as: a = 2.403; notice that the point was shifted forward by 3 units.
So:
n = -3
The equation becomes:


Approximate

Answer:
I believe it's a reflection. I'm doing these in Geometry class right now too.
Step-by-step explanation:
The squares points are all opposite/flipped.
Her best choice would be to take a fixed rate mortgage because it would let her know exactly how much she would pay each month.
Y+Y+30=90
2Y=60 /:2
Y=30
PNQ=30°
QNO=30+30=60°
To solve this system of linear equations we need a little trick called elimination steps are below
we are given the following system of equations


if you look at the x variables in both equations you can see that we can easily eliminate them by multiplying the bottom equation by -4 as so


simplify and we get


now we can combine like terms on each side with the x's cancelling and get

now divide off -35

great now we can go back to our original system and pick a equation and substitute y back in to find x lets use

so now we substitute y and get




now we put x and y into one coordinate (x,y)
so now our FINAL ANSWER IS
(-17,-1)
