Answer:
C
Step-by-step explanation:
The line on the left has equation y = x - 2
The start of the line has an open circle at x = 3 meaning that x ≠ 3
The line is defined as y = x - 2 for x < 3
The line on the right has equation y = x - 1
The start of the line has a closed circle at x = 3 meaning that x can equal 3
The line is defined as y = x - 1 for x ≥ 3
Thus the definition of the function is C

Answer:
Answer for #10:
Answer for #1:
Step-by-step explanation:
In order to solve a simultaneous equation using the substitution method you have to:
Use one of the equation and substitute it into the other equation, in this case equation <em>B</em><em> </em>was substituted into equation <em>A</em><em>.</em>
<em>
</em>
Therefore since x = 1 - y, equation A would be:
This one is so easy that your brain refuses to accept it.
It's looking for a harder answer, but can't find it !
You're totally correct, as far you went. x² + 2x does = -1
Now add ' 1 ' to each side: x² + 2x + 1 = 0
Can you factor that quadratic ?
Can you mash it through the quadratic formula ?
Actually, it's the simplest possible perfect square.
x² + 2x + 1 = (x + 1)²
So the solutions of x² + 2x + 1 = 0 are both x = -1 .
Don't say anything.
I know it's embarrassing.
