Solve the compound inequality for x and identify the graph of its solution. x + 7 < 3 or x - 52 -1 O A. Solution: x < -4 o
aleksley [76]

Answer:

  D.  x < -4 or x ≥ 4

Step-by-step explanation:

You can eliminate choices A and B because the graph and the inequalities do not agree.

__

You can eliminate choice C because the first inequality tells you ...

  x < some value

That means the shading will be to the left of an open circle.

This is only shown in Choice D.

_____

<em>Additional comment</em>

You can work multiple choice questions several different ways. I like to choose the simplest, which often means you do not actually need to work the problem. You only need to be able to identify ...

  • answers that are self-consistent
  • answers that are consistent with problem requirements
  • answers that are consistent with numerical and geometric facts

Here, we can eliminate incorrect answers by throwing out those that are not self-consistent and that are not consistent with the problem statement.

__

If we were to solve the inequalities, we would subtract 7 from both sides of the first one:

  x +7 < 3

  x < -4 . . . . . . subtract 7 from both sides

and we would add 5 to both sides of the second one:

  x -5 ≥ -1

  x ≥ 4 . . . . . . add 5 to both sides

If you write these inequalities so the symbols point left, you have ...

 x < -4  or  4 ≤ x

This tells you shading is "outside" the segment between -4 and 4, and that there is an open-circle at x=-4. This is consistent with the number lines of choices B and D. However, these inequalities are <em>not consistent</em> with what is written in choice B.

In any function, f(x) = a(x-h)n + k , a negative leading coefficient means the graph is reflected.
Sonja [21]
<h2>Answer:</h2>

True

<h2>Step-by-step explanation:</h2>

For any function of the form:

f(x)=a(x-h)^n+k

The coefficient a produces a transformation called a reflection in the x-axis whenever a, that is, this axis is said to be a mirror. Let's take an example, suppose you have a function:

f(x)=4(x-2)^2+5

If the leading coefficient is now -4, then the graph is reflected and the new function is:

f(x)=-4(x-2)^2+5

This is shown in the figure below. The red parabola represents f(x)=4(x-2)^2+5 and the blue parabola is f(x)=-4(x-2)^2+5. As you can see, the red parabola has been reflected and transformed into the blue one.

Is −2π rational or irational?
Maru [420]
Irrational.
Rational means that you can write it as a fraction, you cannot express pi as a fraction therefore it’s not rational
