Answer:
answer is first option

wherein, a = 1, b = -3, c = -5
Answer:
(2x/3) - 4
Step-by-step explanation:
"twice a number" ---> 2x
"quotient of twice a number and 3" ---> 2x/3
"4 less than" --> (2x/3) - 4
Could also be written as (2/3)x - 4
For the first one...
1,15
2,30
3,20
and for the second one is the same as the first one.
EXTRA CREDIT:
Week one increases by 15, week two increases by 15 but week three decreases by 15. The total miles ran would be 15 miles
15+15=30 30-15=15 miles
The slope is 0 and the equation is y = -2
1 liter = 1000 ml
53.1 liter = 53.1*1000 = 53100
Hope this helps :)
