The question is find the equation, in the function and standard notations, that represent the amount spent in the range of 0 to 5 rides.
Constant cost: $30
Independent variable, number of rides: r
Variable cost: $2r
Total spend, s(r): 30 + 2r
Function: s(r) = 30 + 2r, for 0 ≤r ≤ 5 ----- this is the function notation
Standard form: s(r) is the dependent variable = s
s = 30 + 2r => s - 2r = 30 =>
s + (-2)r = 30, for 0 ≤ r ≤ 5 ------ this is the standard form
Answer:
n = -1
Step-by-step explanation:
n^2 + 5n + 1 = 3n
N^2 +2n +1 = 0 (subtract 3n from both sides)
(n+1)(n+1) = 0 (factor
n+1 =0; n= -1
n+1 = 0 ; n=-1
You didn't ask any questions, but there is enough information here to determine how hotter or colder the temperature has become from in the morning till the afternoon.
Answer:
The weather is 20 7/8 degrees hotter in the afternoon than it was in the morning.
Step-by-step explanation:
Romain notices that the temperature was -11 1/2 degrees.
This corresponds to -23/2 degrees.
In the afternoon, the temperature becomes 9 3/8 degrees, which corresponds to 75/8
This statements tells us that therm temperature has been (23/2 + 75/8) degrees hotter than it was initially.
23/2 + 75/8 = 167/8 = 20 7/8
Answer:
60
Step-by-step explanation:
number of miles driven north plus 34 equal 94.
subtract 94 from 34 to get your answer.
