The graphs of f(x) = -2x and g(x)=()* are shown.
1 answer:
The solutions to the equation -2x = 2^x are (1,2) and (2,4)
<h3>How to determine the solutions?</h3>The attached graph represents the missing part of the question
The equations are given as:
f(x) = -2x
g(x) = 2^x
The solution to -2x = 2^x is the points where the graphs of f(x) and g(x) intersect
From the attached graph, the points of intersection are:
(1,2) and (2,4)
Hence, the solutions to the equation -2x = 2^x are (1,2) and (2,4)

Answer:
<h2>$ 22200 in higher yielding bank and $ 44400 in lower yielding bank</h2>Step-by-step explanation:
Jolene invests in two bank accounts. The first account gives a 4% interest per year and the second bank gives a 10% interest rate per year.
She puts twice as much in the lower yielding bank account. Let us denote the amount put in high yielding bank account by . Lower yielding bank account will have
.
Interest from lower yielding bank =
Interest from higher yielding bank =
Total Interest per year = $ 3996 =
∴ Jolene invested $ 22200 in higher yielding bank and $ 44400 in lower yielding bank.
