Answer:
It's 0
Step-by-step explanation:
Answer:
(-3, -6)
Step-by-step explanation:
y=2x
-3x-15=y
Use Substitution Method
-3x-15=2x
+3x +3x
-15=5x
/5 /5
-3=x
y=2x
y=2(-3)
y=-6
With each iteration, you're swapping the two coordinates, and then change sign of the first one:
First transformation
- Start with (3,1)
- Swap coordinates: (1,3)
- Change sign of the first coordinate: (-1,3)
Second transformation
- Start with (-1,3)
- Swap coordinates: (3,-1)
- Change sign of the first coordinate: (-3,-1)
Third transformation
- Start with (-3,-1)
- Swap coordinates: (-1,-3)
- Change sign of the first coordinate: (1,-3)
<span>4x^2-36x/x-9
= 4x(x-9) / (x-9)
if 4x = 0, ⇒ x = 0
x-9 ≠ 0
zero of function is 0.
