Answer:
Yes, she is correct.
Step-by-step explanation:
y = kx is direct variation
15 = k*-3
k = -5.
So the equation of variation is
y = -5x
When x = -4:
y -5*-4 = 20.
Answer:
Step-by-step explanation:
x < -12, so x+12 < 0
| x-(-12) | = | x+12 | = -x-12
The answer would be 2 over 3, or 2/3. (:
A. Is not linear because is has no y
How this helped ya out! :D
