Answer:
⅚
Step-by-step explanation:
Greater than 2 or even:
2,3,4,5,6
Probability = 5/6
f(x) = 3(x^2 + 3x) + 12 = 3(x+1.5)^2 +5.25
So you can see the vertex is at (0,5.25) when x = -1.5
<span>The axis of symmetry then lies in x = -1.5</span>
Answer:
z + 12
Step-by-step explanation:
Combine like terms (terms with the same amount of variables).
2z + 9 - z + 3
(2z - z) + (9 + 3)
z + 12
z + 12 is your answer.
