Answer:
C) The solution for the system of equations
Step-by-step explanation:
Point (3, 120) is where both lines intercept!
Basically, (3, 120) is where both equations are equal to each other.
(120 = 20(3) + 60) = (120 = 40(3))
We can test it!
120 = 20(3) + 60
120 = 60 + 60
120 (Correct)
120 = 40(3)
120 = 120 (Correct)
Answer:
x = -2 ± 452i
Step-by-step explanation:
x² + 4x = 117
x² + 4x - 117 = 0
if you solve this quadratic by using the quadratic formula you get:
x = -2 ± 452i
452i is an imaginary number that equals
