Step-by-step explanation:
1) for t = 0, the initial value is -0.45 gal. which is funny. when it is really cold, do people add water to the tank somehow instead of consuming water ?
so I guess, that system is really reliable with values greater than 0.
0.0875t = 0.45
t = 5.142857143...°
so, I guess, 6° is the lowest reasonable value for this function.
2) as for any line function, the slope is the rate of change.
so, 0.0875 gal more per 1 degree more in temperature.
3) t = 90
w = 0.0875×90 - 0.45 = 7.425 gal
Answer:
$108
Step-by-step explanation:
18 dollars times 6 equals 108.
Answer:
Additive inverse of 6/5 is -6/5
Multiplicative inverse of 6/5 is 5/6
Additive inverse of -1/9 is 1/9
Multiplicative inverse of -1/9 is -9/1
Additive inverse of 1 is -1
Multiplicative inverse of 1 is still 1 or 1/1

Answer:
$147
Step-by-step explanation:
Bridget gets: x
Stephen gets: 3x
Richard gets: 2(3x) = 6x
Total = 10x = 490
x = 49
Stephen gets: 3x = 3(49) = $147
