Answer:

So the answer is 0.5

Step-by-step explanation:

We'll assume the dilation was done at the origin point, so it was done evenly.

Since the k point went from (10,0) to (5,0), we know it was reduced... so the scale factor has to be below 1. A scale factor means the size wasn't changed and a dilation/scale factor larger than 1 means it was enlarged.

So, we take the new X-value (5) and divide it by the original X-value (10).

Scale factor = 5/10 = 1/2... so 0.5

Answer:

The scale factor of the following dilation is, 0.5

Step-by-step explanation:

The rule of dilation with scale factor k is given by:

(x, y) \rightarrow (kx, ky)

As per the statement:

Given the following dilation:

(10, 0) → (5, 0)                 .....[1]

We have to find the scale factor.

Using the above rule we have;

(10, 0) \rightarrow (10k, 0k)

Now compare this with equation [1] we have;

(10k, 0) = (5, 0)

⇒10k = 5

After solving we get;

k = \frac{1}{2}=0.5

Therefore,  the scale factor of the following dilation is, 0.5

How can you represent all of the solutions to systems of inequalities?​
Dimas [21]

Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations. Step 4: Solve the one variable system.

Step-by-step explanation:

hope this helps have a great night ❤️❤️❤️
