<span>y + 4 ≤ 0
----------------------
Subtract 4 from each side
</span><span>y + 4 - 4 ≤ 0 - 4
</span>y ≤ -4
y ≤ -4 is the answer
No there's a difference between it, I know what it was on the tip of my tongue but I forgot it <span />
Answer:
77.5°
Step-by-step explanation:
Draw a picture.
tanθ = 346/77
θ = arctan(346/77) ≅ 77.5°
For
y=a(x-h)^2+k
the axis of symmetry is x=h
so
y=2/3(x-2)^2-5
the axis of symmetry is x=2
answer is C
