Answer: C) perpendicular</h3>
Explanation:
Each equation given to you is in y = mx+b form (aka slope intercept form).
The slope m is what we'll focus on.
The first equation has slope of 1, while the second equation has slope -1.
The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.
Or you could note that -1 is the negative reciprocal of 1, or vice versa.
So there are a few options to see why the lines are perpendicular.

<h2>C) (-4, -4)</h2>
Step-by-step explanation:
If y = ax² + bx + c has negative value of a, then a parabola is open down.
Look at the picture.
Vertex = (-4, -4)
Answer:
126
Step-by-step explanation:
This is a tricky question!
So we can quickly find the area of the whole circle through πr². That would be around 144π (remember, we are solving in terms of π, so we dont use 3.14)
Then, the circles. Through πr², we can find that the area of one circle is 9π. And since there are two circles, we can add these together to become 18π.
Now we subtract 144π from 18π to find the shaded area. 126π, and since we are doing this in the terms of π, we don't need to include that.
