We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.
Answer:
9 degrees
Step-by-step explanation:
given:
Initial temperature : 17 degrees
temperature change = reduction by 8 degrees (i.e - 8 degrees)
hence the final temperature
= initial temperature + temperature change
= 17 + (-8)
= 17 - 8
= 9 degrees
Answer:
Below.
Step-by-step explanation:
y + 2 > -3(x + 1)
y + 2 > -3x - 3
y > -3x - 5
The graph will be the graph of the line y = -3x - 5 (dotted line), with the area above the line shaded.
Answer:
-13
Step-by-step explanation:
42-55=-13
If this is the case, then you know by the polynomial remainder theorem that

is a factor of

, so there is some polynomial

such that
