Answer:
True
Step-by-step explanation:
we know that
A non-negative number is a real number greater than or equal to zero
In this problem
we have

The solution of the inequality is all real numbers greater than or equal to zero [0,∞)
Therefore
express a non-negative number in symbols
Answer:
0.23 centimeters per hour
Step-by-step explanation:
Answer:
see the procedure
Step-by-step explanation:
we have

where
c -----> the cost in dollars
g ----> the number gallons of gas purchased
1) For g=1 gal
substitute the value of g in the equation and solve for c


The pair (1,2.95) fit the relationship
2) For g=3 gal
substitute the value of g in the equation and solve for c


The pair (3,8.85) fit the relationship
3) For g=5 gal
substitute the value of g in the equation and solve for c


The pair (5,14.75) fit the relationship
4) For c=$20.65
substitute the value of c in the equation and solve for g



The pair (7,20.65) fit the relationship
