Answer:
-3
Step-by-step explanation:
It is line/linear because for it to be a parabola the x would have to be squared.
Answer:
−8x+6y−12
Step-by-step explanation:
Distribute:
=(2)(4)+(2)(−2x)+(2)(y)+(−4)(5)+(−4)(x)+(−4)(−y)
=8+−4x+2y+−20+−4x+4y
Combine Like Terms:
=8+−4x+2y+−20+−4x+4y
=(−4x+−4x)+(2y+4y)+(8+−20)
=−8x+6y+−12
A=42
C=90
B=48
We can reason that C will be equal to 90 since it is the right angle. So to find B we have to subtract 90 from 180 to get 90 then subtract 42 to get 48
B=48 degrees
