Answer:
1) 7 Miles
2) $750
3) I did not get what it was asking, sorry.
Step-by-step explanation:
1) It is 5 dollars per mile.
You can divide 35 by 5 to get to 7 miles.
2) You find the constant by dividing one of the pairs, in this example, I chose the first row of numbers.
Divide $100 by 4, which will get you $25 per session.
Multiply 30 by 25 which will get you $750
We will use the distributive property. -4 times 9z=-36z -4 times -2=8 so we have -36z+8 as our answer
Alright so x is equal to 20
then 6 times 20= 120 and then 120-28=92
then you add 92+48=140
then 2 times 20=40 and 140+40=180 which is your answer
Answer:
a. The given equation is d = -75·t + 275 is a function
b. f(t) = -75·t + 275
c. 275 km
d. The situation does not makes sense for t > 11/2 hours.
Step-by-step explanation:
a. Given that a relation is a functional relation if for each input of a member in the relation, there is only one output for the other member, therefore;
The given equation is d = -75·t + 275 is a function
As when t = 1, d = 200 km
b. The equation written in functional notation, f(t) is f(t) = -75·t + 275
c. At the start of the journey, t = 0
Therefore;
f(0) = -75×0 + 275 = 275 km
d. The values of t that do no make sense in the function are given as follows
0 = -75×t + 275
t = 275/75 = 11/3 = 3.67 hours
For times above 3.67, the distance becomes negative
Therefore, the situation does not makes sense for t > 11/2 hours.
