Complentary angle = 90 degrees
90 - 16 = your answer
(-1)(-1)(-1)+(-1)=-1-1=-2
-2
Hope this helps!
Answer:


Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

For 0.4(20y+15)=x, we expand to get:


Divide through by 8

Therefore the system in slope-intercept form is:
