It would be 800 because the number behind it is 0
First day : 30+20y
Second day : 85 + 17y
Total: 30 + 20y + 85 + 17y This is the not simplified version.
37y+115 This is the simplified version.
If she reflects across the x-axis, then the y-values will change.
The y-values will be opposite their original values.
(-6, -4) and (-2, -4) are the two new points after the transformation.
Hope this helps!
2.5 * 10^(-4) * 3 * 10^5 =
= 2.5 * 3 * 10^(-4) *10^5
= 7.5 * 10^(-4 + 5)
= 7.5 * 10^1
