Answer:
x-int: (-1, 0), (-11, 0)
y-int: (0, 11)
Step-by-step explanation:
To find x-int, set equation equal to 0:
x² + 12x + 11
(x + 1)(x + 11)
x = -11, -1
To find y-int, set <em>x</em> = 0
f(0) = 0² + 12(0) = 11
f(0) = 11
Answer: $12000 was invested at 7% while $8000 was invested at 9%.
Step-by-step explanation:
Based on the information given in the question, let the amount that was invested at 7% be n.
Therefore,
0.07n + 0.09(20000 - n) = 1560
0.07n + 1800 - 0.09n = 1560
-0.02n = 1560 - 1800
-0.02n = -240
n = 240/0.02
n = 120
Therefore, $12000 was invested at 7% while $8000 was invested at 9%.
