Answer:

[2,3] is the answer

assuming you didn't have equal symbols under the inequality signs, you know \le and \ge.

Step-by-step explanation:

Ok let's solve 3x+4>13 or 1/2 x+3<4.

Let's begin with 3x+4>13.

3x+4>13

Subtract 4 on both sides:

3x>9

Divide both sides by 3:

x>3

Now the other 1/2 x +3<4.

Subtract 3 on both sides:

1/2 x<1

Multiply both sides by 2:

x<2

So we have x>3 or x<2

If we graph this, this will give us better idea of what is and isn't a solution.

~~~~~~~~O                            x<2

                             O~~~~~~ x>3

------------(2)---------(3)---------

The only numbers not included are between 2 and 3 (inclusive).

So if x is between [2,3] then A or B has no solution.

A student graphed f(x)=x and g(x)= f(x)-8 on the same coordinate grid. Which statement best describes how the graph of f and g a
luda_lava [24]

Answer:

The correct option is D

The graph of f is shifted 8 units down to create the graph of g.

Explanation:

Given f(x) = x

If the graph of this function is shifted 8 units down, we have

x - 8

This is the function f(x) - 8

Since g(x) = f(x) - 8, we conclude that the graph of f is shifted 8 units down to create the graph of g.
