Answer:
-16
Step-by-step explanation:
The given linear function is ; 
Let
.
We interchange x and y.
.
We solve for y.
.
We now multiply through by
to get:
.
This simplifies to;
.
Hence
.
The y-intercept is -16
If you mean 720/10^3, you do 10*10*10. This equals 1000. Now, do 720/1000. This is 0.72, or 72/100, which is your answer.
Y=145
Explanation:
A triangle’s angles add up to a total of 180 so you would subtract 55 from 180 and then subtract 90 because of the right angle, then you would end with x=35. Since x and y are supplementary they add to 180...so then you subtract 35 from 180 and then you get y=145.
