Answer:

None of the given option is correct.

Step-by-step explanation:

The expression given is:

-18-(-9)

= -18+9

= -9

Now checking the options, which will have -9 as answer

1) 0 -18+2

= -18+2

= -16

As answer is not -9, so this is not a correct option

2) 9 -12-(-3)

= 9 - 12 + 3

= 0

As answer is not -9, so this is not a correct option

3) -10-5

= -10-5

= -15

As answer is not -9, so this is not a correct option

So, None of the given option is correct.

A triangle is dilated by a scale factor of 1/5 and then rotated 90 degree clockwise about the origin. Why is the image similar t

yan [13]

Answers:
The corresponding angles of the triangles are congruent
The image is a reduction of the pre-image
Neither the dilation nor the rotation change the shape of the triangle

Explanation:
For shapes to be similar:
1- there should be a ratio between the sides
2- angles in first shape should be congruent to angles in second shape

Now, a scale factor of 0.2 means that the sides of the image are 0.2 of the length of the original shape. However, angles are not changes

Let's check the choices:
1- The corresponding sides of the triangles are congruent:
This option is incorrect as dilation changes the lengths of the sides

2- The corresponding angles of the triangles are congruent:
This option is correct as neither dilation nor rotation alters the measures of the angles

3- The corresponding sides of the image are 5 times as long as those of the pre-image:
This option is incorrect as the sides of the image are only 0.2 times as long as those of the pre-image

4- The image is a reduction of the pre-image:
This option is correct as the sides of the image are 0.2 times those of the pre-image which means that the shape is reduced

5- Neither the dilation nor the rotation change the shape of the triangle:
This option is correct as both dilation and rotation are rigid transformations that do not alter the shape of the triangle (a triangle remains a triangle only with different side lengths)

6- The rotation reduces the size of the triangle:
This option is incorrect as rotation does not alter the size of the shape. It only changes its position

Hope this helps :)

Determine the domain of the function.

Dafna1 [17]

We are given with a verbal phrase of a function of x is equal to the square root of x plus one divided by x plus four times x minus six.

This is expressed as f(x) = √(x) + 1/x + 4x - 6
the domain are values which include only natural numbers because of the square root sign. answer is D. x ≥ 0
