The first equation in the following system gives the
1 answer:
The solutions to the system of equations are (b) (-1,170, -23,400) and (170, 3,400)
<h3>The solutions to the system of equations</h3>The attached image represents the proper format of the question
The equations are given as:
y = -0.01(x - 500)² + 4489
y = 20x
According to the question;
When y = 20x is substituted in the first equation, the equation becomes
0 = -0.01x² - 10x + 1989
Rewrite as:
-0.01x² - 10x + 1989 = 0
Next, we solve using a statistical calculator.
From the calculator, we have:
x = -1170 and x = 170
Substitute x = -1170 and x = 170 in y = 20x
y = 20 * -1170 = -23400
y = 20 * 170 = 3400
Hence, the solutions to the system of equations are (b) (-1,170, -23,400) and (170, 3,400)
