We know that perpendicular lines have slopes which are negative inverses of each other. This means that the slope of the line we are going to need to find is 3.

Now, we can use the point-slope formula to find the actual equation of the line we are trying to find. The point-slope formula is $(y - y_1) = m(x - x_1)$ , where $y_1$ and $x_1$ are the coordinates of a point on the line and m is the slope.

Thus, the equation of the line we are trying to find is:
(y - 7) = 3(x - 2)
y - 7 = 3x - 6
y = 3x + 1

However, this is not an answer choice. The answers given have the constant on the right side of the equation. Thus, we will make our answer have the constant on the right side:
y - 3x = 1
-3x + y = 1
3x - y = -1

This is an answer choice. B, or 3x - y = -1 is the correct answer.

Answer:

16 rounded to the nearest 10 is 20

21 rounded to the nearest 10 is 20

so I don't really know but I guess you should put the x as 20 for sure UwU

1. Complete the inequality below to describe the

dezoksy [38]

Domain is the entire span left to right (on the x-axis) that the graph is on. Since the graph goes from x=-4 and ends at x=4, the domain would be from -4 to 4. The circle at -4 is open, so it does not include the point at -4, just everything leading up to it. So, the domain would be

$- 4 < x \leqslant 4$

The range is similar, it is the entire span that the graph goes up and down (on the y-axis). The graph starts at the bottom at y=-2, and ends at y=5. The bottom point (4,-2) is closed, so the graph includes that point, and the top point (-4,5) is open and doesn't include the point. Therefore, the range would be

$- 2 \leqslant x < 5$
