1. The coefficient of the squared term (-1/3) is negative, so the graph opens downward.
2. Matching the pattern to
.. y = a(x -h)^2 +k
we find (h, k) = (-2, 5) . . . . . . selection C
3. See the previous answer. The axis of symmetry is
.. x = h
Since h = -2, the axis is x = -2. . . . . . selection B
Answer:
Commutative Property
Step-by-step explanation:
Answer:
y=1/3x+5/3
Step-by-step explanation:
y=3x-5
x=3y-5
3y=x+5
y=1/3x+5/3
Answer:
B. A=6 B=-25, C=14
Step-by-step explanation:
(3x -2)(2x-7)
Using FOIL
= 6x^2 - 21x - 4x + 14
= 6x^2 -25x + 14
So a = 6, b = -25 and c = 14
answer
B. A=6 B=-25, C=14
