A
Given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
The x-coordinate of the vertex is
= - 
y = - 3x² + 2x - 7 is in standard form
with a = - 3, b = 2 and c = - 7, hence
= -
= 
Substitute this value into the equation for y-coordinate
y = - 3 (
)² + 2 (
) - 7
= -
+
-
= - 
vertex = (
, -
) → A
Answer:
3(3b + 4)
the GCF is 3
Step-by-step explanation:
8
46
is equivalent to 4
23
because 4 x 2 = 8 and 23 x 2 = 46
12
69
is equivalent to 4
23
because 4 x 3 = 12 and 23 x 3 = 69
16
92
is equivalent to 4
23
because 4 x 4 = 16 and 23 x 4 = 92
Answer:
three-thirty (3:30)
Step-by-step explanation:
An hour is 60 minutes, so half an hour would be 30 minutes. Half past 3 would also be 30 minutes past 3, or 3:30.
I hope this helps!! :) Have a lovely day!!!
