Step-by-step explanation:
I assume that you mean
sec(x)-tan(x) = 1 / ( sec(x) + tan(x) ) , right ?
then this is equivalent to
[ sec(x) - tan(x) ] x [ sec(x) + tan(x) ] = 1
let s evaluate it, we got
sec2(x) - sec(x)tan(x) + - sec(x)tan(x) - tan2(x) = sec2(x) - tan2(x)
= (1 - sin2(x) ) / cos2(x) = cos2(x) / cos2(x) = 1
as cos2(x) + sin2(x) = 1
Answer:
(0,-9)
Step-by-step explanation:
The image of a point 
over a line 
is given by the co-ordinate rule:
→ 
So, when we reflect a point over the line , the x co-ordinate and y co-ordinate change their places.
Here, is 
. So, from the above rule, after reflection over the line , the image has the following co-ordinates:
4 packages of hotdogs and 5 packages of rolls
