The length of AB is 9 centimeters. A dilation with a scale factor of 2 is applied to AB. What is the length of the image AB afte
OLEGan [10]

Answer:

18cm

Step-by-step explanation:

Given:

- The length of AB is 9 centimeters

- A dilation with a scale factor of 2

The length of the image AB after the dilation is applied:

9 x 2 = 18

dilation is used to make an image or in this case AB, with a scale factor of 2 means that its doubling in size. If the scale factor was 1/2 that it would be decreasing in size since it will be half of the original size

Write the following equation in the general form
shtirl [24]
<h2>Explanation:</h2>

As I understand, the given equation is:

5 y = x-1

So we need to write this into general form. The general form of the equation of a line is given by:

Ax + By + C = 0

Where A and B can't be zero at the same time. So subtracting 5y from both sides:

5y-5y = x-1-5y \\ \\ 0=x-1-5y \\ \\ \\ Arranging: \\ \\ \boxed{x-5y-1=0} \\ \\ \\ So: \\ \\ A=1 \\ \\ B=-5 \\ \\ C=-1

Given that ∠A and ∠B are supplementary, Daisy conjectured that ∠A≅∠B .
dexar [7]
When two angles are supplementary, that means that the sum of their individual angles is equal to a straight line, which is 180°. If you add another restriction where the two supplementary angles are equal, then each vale of the angle constitutes half of 180°. Then, that means that ∠A = ∠B = 90°. The answer is C.
