Two rules come into play here:
1) We cannot divide by zero. Thux, x cannot = -3.
2) The domain of the square root function is (0, infinity). This is the dominant limiting factor.
x + 3 must be > 0. Thus, x must be > -3
The domain of this expression is (-3, infinity).
Answer:
277.5m²
Step-by-step explanation:
Just multiply.
Answer:
What shapes are you talking about?
Step-by-step explanation:
Answer:
Infinitely many
Step-by-step explanation:
2x + 2y = 8
x + y = 4
4x + 4y = 16
x + y = 4
Basically they represent the same line.
So all points on the line will satisfy both equations.
Hence infinitely many solutions
