Answer 2

Answer:

Answer to (4+5): (0,0)

Answer to 6: 0

Step-by-step explanation:

(4+5 Explanation):

We can start to imagine the graph of $y=|x|$ in our head.

If we have a positive value of x, then y will be equal to x.

If we have a negative value of x, then y will be the opposite of x (since the absolute value of a negative is a positive).

This means that the graph will look a bit like this, changing at the point (0,0).

\/, it would look like a downward facing arrow. This means the vertex is at (0,0).

6 Explanation:

If we know the value of $w$, we can substitute it into the expression $2w+w-15$ as 5.

$2(5) + 5 - 15\\\\10 + 5 - 15\\\\15-15\\\\0$

Hope this helped!
