Solve the inequality for V.<br><br> -8.3 _&gt;_ V - 1.9
Arada [10]
First keep in mind that the given value is negative and that it is greater than or equal to whatever '<em>v</em>' is.

-8.3  \geq v - 1.9

When solving for a variable in any equation, you do something to both sides in order to keep it equal. Here, <em>v</em> is being subtracted by 1.9; therefore we can add 1.9 to both sides in order to isolate <em />the variable.

-8.3 + 1.9  \geq v - 1.9 + 1.9
-6.4 \geq v

Despite not needing a value for the question, it is worth noting that since this is an inequality, <em>v </em>can be any value from -6.4 to ∞ in order to make it true.

Consider the following data set:
Komok [63]

Answer:

+5 Range; The range is now 25

Step-by-step explanation:

The original range would be calculated by subtracting 20 from 40, giving you 20 as the range. However, with the point 15 added, there would be a new lowest number, making the new range be 40-15, which is 25.

Allan drew a polygon with 4 sides and 4 angles. All four sides are equal. None of the angles are right angles. What figure did A
Lady_Fox [76]

Answer: The figure drawn by Alan is a rhombus.


Step-by-step explanation:

Given: Allan drew a polygon with 4 sides and 4 angles with two properties:-

  • All four sides are equal.
  • None of the angles are right angles.

We know that only a rhombus is a flat shape with 4 equal straight sides and 4 angles .All sides have equal length. Its angles need not to be right angle.

Therefore, the figure drawn by Alan is a rhombus.

The point below will be reflected over the line y = x and then translated two units left and one unit up.5421-5-4-3-2-10234-1-2-
charle [14.2K]

A reflection over the line y=x implies exchanging the x and y coordinates of a point. For example if you take a generic point (a,b) then its reflection over y=x is (b,a). Our point is (-1,3) so its reflection over y=x is the point (3,-1).

Then we have to translate it two units left. Translating a point left means that we are moving towards negative x values so we need to substract 2 from the x coordinate:

(3,-1)\rightarrow(3-2,-1)=(1,-1)

Finally we have to translate it 1 unit up towards positive y values so we have to add 1 to its y coordinate:

(1,-1)\rightarrow(1,-1+1)=(1,0)

And these are the final coordinates. In the following picture you have the points you get after each step (from A to D) with the y=x line in blue:
