It would be 4 because, on the right, it has 3 and 4. That is 7 and if you look at the scale it's balanced which means it would be the same on that side but it already has 3 so 4. So hold up your fingers and take 4 fingers up and add 3 fingers to that 4. How many is that? Count them all up and you'll get 7!

N+3=7. To find n, you need to have it by itself, so you can do that by subtracting 3 on both sides, so it would look like: n+3-3=7-3. Then you have n=4.

How can you change the equation y = mx + b to shift the graph down?

IrinaK [193]

Step-by-step explanation: To shift the graphs up and down on the coordinate system, you need to manipulate or change the y-intercepts.

The y-intercept is just the constant term in the equation.

As long as the slopes remain the same, the graphs can be

translated up or down by changing the constant value.

Take a look at these lines graphed below.

Notice that y = x + 11 is the same as y = x + 4 but

y = x + 11 is translated 7 units down to get y = x + 4.

What relationship is formed by a line of symmetry and the line between opposite points in the symmetry

Anettt [7]

Answer:

A line of symmetry and the line between opposite points in the symmetry are perpendicular to each other.

Explanation:

A line of simmetry splits the figure into two identical halves.

Suppose you have a symmetrical plane figure (like a square or a circle), the line of symmetry divides such figure in two sides: call them the left side and the right side.

The reflection of each point on the right side is a point on the left side along the perpendicular line that joins the two points and the line of symmetry.

For instance, if the line of symmetry is vertical, such as the x-axis, the line between the opposite points in the symmetry is horizontal, i.e. perpendicular to the x-axis (the line of summetry).
