Answer:
Since the graph never crosses the x-axis, the function has no real zeros
Step-by-step explanation:
The real zeros <em>are</em> the x-intercepts.
This graph has neither. Since the graph never crosses the x-axis, there are no real zeros.
No it's positive since if you multiply both sides by -1 you will get 5m=20 & m=4
Another method -5m =-20, divide both sides by -5, you will get the same positive m =4

Answer:
• $250
,
• y=200+50x
,
• Graph A
,
• Yes
Explanation:
(a)Han cellphone's plan costs a fixed fee of $200 and an extra $50 per month.
Therefore:
(b)If Han uses the phone for x months
Extra Cost = 50x
Therefore:
(c)Since the number of months = x; and
Total cost for x months = y
When x=24
The graph that shows the cost of the cell phone plan over a period of two years using months as the units of time is Graph A.
(d)We see that the equation y=50x+200 has a proportional constant (50).
Another approach is to say that it is a linear equation.
Therefore, there is a proportional relationship between time and the cost of the cell phone plan.
