Answer:
Parallel
Step-by-step explanation:
in a Standard from equation, Ax+By=C
slope=-A/B
The slope of first line is -3/-1=3
The slope of second line is -6/-2=3
Same slopes but different C values mean they r parallel.

:
3x+2=17
-2 -2
3x=15
/3 /3
x=5
It's dependent on the context. A book may ask you to find the f'(x) of a function and you may have to use a u sub in your problem which requires you to find the dy/dx of what you substitute. So in this case both would be used.
1. YX = 8√3/tan60° = 8
so ZX = ZY + YX = 10 + 8 = 18
2. angle Q
Answer:
x=14
PQ=46
Step-by-step explanation:
PT and TQ are equal, so we can set up the equation like this: PT=TQ
23=2x-5
calculate to find x
x=14
PQ is just PT+TQ so 23+23=46
