Answer:

Option B -(-8\frac{1}{4})

Step-by-step explanation:

we know that

The opposite or additive inverse of a number a is the number that, when added to a, yields zero.

so

The opposite of a is -a

In this problem we have

8\frac{1}{4}

therefore

The opposite is

-8\frac{1}{4}

and the opposite of the opposite is

-(-8\frac{1}{4})

Answer quickly! It very urgent
ra1l [238]

Answer: Because the graphs of the two equations overlap each other

Step-by-step explanation:

Every point on the first line also satisfies the second equation.

This is the same as equivalent fractions

where 1/2 = 2/4 = 3/6 = 4/8

Graphing these on a number line would only show one dot.

What is the graph point for x + y ≤ 6?
zmey [24]

Step-by-step explanation:

x + y ≤ 6

You'll have to express the linear inequality into an equality statement (in slope-intercept form, y = mx + b) in order to graph. You'll have to use a solid line because of the "≤ " symbol.  

                                                        y = - x + 6

Next, you'll have to choose two points to use for graphing. It's always safe to start with the y-intercept, (0, 6).

From there, you could use the slope (m = -1) and do the "rise over run" technique to plot your next point. Going up 1, left 1 will get you to (-1, 7); going down 1 right 1 will get you to point (1, 5). Connect your points and create a straight line.  

Next, to determine which region to shade, you must choose a convenient test point (that's not on the line) to see whether the given test point will satisfy the inequality statement.  

Let's choose the point of origin, (0, 0), and plug its values into the inequality statement:

                                 x + y ≤ 6

                                0 + 0 ≤ 6

                                      0 ≤ 6 (True statement). This means that you should shade the half-plane region where the test point is located (left side of the plane).

The first screenshot shows how I created the lines by plotting the first three points. The second screenshot shows the actual graph with the shaded region.

Please mark my answer as the Brainliest if you find this explanation helpful :)
