Answer:
Not a function because there are two values of y for x = -8.
Answer:
y = -2x + 3
Step-by-step explanation:
4x + 2y = 6
⇔ 2y = 
Answer:
56
Step-by-step explanation:
from theorem , VR/SR=VU/UT
28 + vector b = -12
vector b = -40
vector b has magnitude 40 units in the negative y direction.
= (y+6) +y =10
= 2y + 6 = 10
= 2y = 4
Y= 2
