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

Answer:
A
Step-by-step explanation:
Plug 2 in for y in the second equation. You get 3 as x. So x=3 and y=2. (3,2)
Answer:
y = - 4x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x ++ c ← is the partial equation
To find c substitute (- 3, - 1) into the partial equation
- 1 = 12 + c ⇒ c = - 1 - 12 = - 13
y = - 4x - 13 ← equation of line
