Answer:
A
Step-by-step explanation:
Answer:
$55
Step-by-step explanation:
Start with $245.
Calculate to total money the commuter needs to buys 20 weeks of tickets.
Multiply the number of weeks by the price per week.
20 X $15 = $300
He will need $300 for 20 weeks of tickets.
Subtract what he has from the amount he needs.
$300 - $245 = $55
Therefore the commuter will need to add $55 to the account to afford tickets for 20 weeks.
Viewing the two equations (by graphing them), we can see that the y axis is the vertical one and the x axis is the horizontal one. If something were to be reflected over the y axis, it would be flipped around x=0 and the x value of every point would be multiplied by -1. If it was reflected over the x axis (y=0), every y value would be multiplied by -1. Taking two points that have the same absolute values, e.g. (-1, 0) and (1, 0) (by absolute values I mean that (|-1|, |0|)=(|1|, |0|)=(1, 0)) we can see that -1*-1=1 and 1*-1=-1. Since they are the x values, it is reflected across the y axis - you are correct!
