Answer:
y = x + 8
Step-by-step explanation:
(x² + 6x - 9)/(x - 2)
[x² - 2x + 8x - 16 + 7]/(x - 2)
[x(x - 2) + 8(x - 2) + 7]/(x - 2)
x + 8 + 7/(x - 2)
Oblique asymptote: y = x + 8
$9 per hour for 14 hours the first week can be found by doing 9 • 14, which equals 126.
In the first week, Erika earned $126.
$9 per hour for 20 hours for the second week can be found by doing 9 • 20, which equals 180.
In the second week, Erika earned $180.
To find the total amount Erika earned in both weeks, add how much she made in week 1 to how much she made in week 2.
126 + 180 = 306
Erika made $306 during these 2 weeks.
