Answer:
The amount invested at 4% is $20,500 and the amount invested at 10% is $500
Step-by-step explanation:
Let
x -----> the amount invested at 4%
(21,000 -x) ----> the amount invested at 10%
we know that
The interest of the amount invested at 4% plus the interest of the amount invested at 10% must be equal to $870
so
Solve for x
therefore
The amount invested at 4% is $20,500 and the amount invested at 10% is $500

The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible. Converting the fraction 35 to a decimal, we would say there is a 0.6 probability of choosing a banana. This basic definition of probability assumes that all the outcomes are equally likely to occur.

1. Re-write the equation to y = mx + b:
-10y = 7x +3
y = -7/10x - 3/10
2. Replace the values and solve:
5 = -7/10(8) - 3/10
5 \neq -5.9
--------------------
-9 = -7/10 (-12) - 3/10
-9 \neq 8.1
This is not a good model because when you solve the equations they do not equal y
Keep in mind that "ln" is just a shortcut for the logarithm with a base of "e".
