Answer:
The solution is the point (-2,-2)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B
Solve for x
Find the value of y
substitute the value of x in the equation A
so

The solution is the point (-2,-2)
<h2>Answer</h2>
f(x) = 190(1.15)x
<h2>Explanation</h2>To solve this, we are going to use the standard exponential function:
Where
is the final price after
years
is the initial price
is the rate in decimal form
is the time in years
We know from our problem that the initial price is $190, so . Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so
. Let's replace the values:
