Answer:
Step-by-step explanation:
Find 3 ratios that are equivalent to the given ratio. 5/15
1 : 5 (0.2)
3/15 (0.2)
4 : 20 (0.2)
A situation could be when you have a y=axsquared+bx+c equation. You'd find the X, or vertex, by doing x=-b divided by 2•a. Then you'd plug in x and find y. Now you have a point you can plot. To find another, you can find the y-intercept by plughing in 0 for x and finding another y.
For his total monthly bill to be under a twenty dollars he could make a 149 calls
20-5=15
15/.10=150
150-1=149
15-.10=14.9
14.9+5=19.9
So the maximum number of calls he can make is 149 a month
Answer:
