Answer: D) P(x) = -23
Step-by-step explanation:
Substitute 2 for x:
1 - 2(2)^2-3(2)^2+4(2)
Exponent
1-2(4)-3(8)+4(2)
Multiply
1-8-24+8
Combine like terms
-23

We know that the average temperature surface in neptune is : - 210 degree Celsius
Thee average temperature surface in mars is : -85 degree Celsius
The net change would be an increase in 125 degree celsius<span />

See explanation
Step-by-step explanation:
A. Gasoline fill-up fee = $4.50
Cost per hour = $40
Average cost = C
Number of hours the scootcar is rented = h
Cost per h hours = $40h
Total cost = $40h + $4.50
Hence,
C = 40h+4.5
B. To plot the graph of the function, find h- and C- intercepts.
When h = 0, then C = 4.5, and we have point (0,4.5)
When C = 0, then 0 = 40h + 4.5, h = -45/400 = -0.1125, and we have point (-0.1125,0)
Plot these two points and connect them with a straight line.
Graph is attached, but you should take only that part of the graph that corresponds to points with h > 0, because the number of hours cannot be negative
Answer:
Step-by-step explanation:
Lets add +5 in both the sides.
Now lets divide 12 on both the sides.
