Answer:
The amount invested at 6% is $12,857.14
The amount invested at 13% is $17,142.86
Step-by-step explanation:
Let
x ----> the amount invested at 6%
30,000-x -----> the amount invested at 13%
we know that
The interest earned by the amount invested at 6% plus the interest earned by the amount at 13% must be equal to the interest earned by the total amount of $30,000 at 10%
Remember that
so
The linear equation that represent this situation is
solve for x
therefore
The amount invested at 6% is $12,857.14
The amount invested at 13% is $17,142.86

<h3>i HOPE IT'S HELP </h3>
So what you would do is A times X + 4 x y = 43 so you have to find out what A, X, and y are to find the answer, so you can do 5 x 7 + 4 x 2 = 43
The vertex is (26,14)
Because it’s written in vertex form which y=a(x-h)^2 + k. H is the x for the vertex And h is changed to it’s opposite. So since 26 is negative it would actually be positive 26. While k ls the y of the vertex which is 14 in our case
Answer:
To solve, we need to isolate the variable
The first step is to subtract 18 from both sides to "reverse" the addition
-6x+18=-6
-6x=-24
The second step is to divide -6 on both sides to "reverse" the multiplication
-6x=-24
x=4
Hope this helps! :)
