Answer:
1472
Step-by-step explanation:
18-3n+2=-3n+20 soo 20-3n=-3n+20 sooo 20=-3n+20+3n soo 20=20...... the following solution is all reals......
4:45 -3:30 -2*(0:15) = 0:45
Gina and Lucy can spend 45 minutes at the library.
_____
They will get to the library at 3:45. They must start home by 4:30. From 3:45 to 4:00 is 15 minutes, and it is 30 more minutes to 4:30. The time they can spend at the library totals 45 minutes.
Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:

Vertex:

X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
