Answer:
Option A (k < -1).
Step-by-step explanation:
Enlargement is one of the linear transformations which changes the size of the shape formed by a combination of some points in the exact proportion. For enlargement (also called dilation), there are two parameters required: the center of enlargement, according to which the transformation occurs, and the scale factor, the size by which the transformation is done. The scale factor can be of any number k. If k is larger than 1 or -1, then it will cause enlargement. If k is between -1 and 1, it will cause anti-enlargement. The magnitude of k determines the size and the sign of k determines the direction. So in this case, k < -1 will cause the enlargement: even though the scale factor is less than -1, but it will enlarge the shape on the opposite direction. Option B and Option C cause anti-enlargement and Option D cause no enlargement or anti-enlargement. So Option A is the correct answer!!!

<u>Answer:</u>
Total number of result at two polling location in a page election is represented by expression 8r + 11.
<u>Solution:</u>
Given that a page election result can hold r result.
Number of result at one polling location = 5r + 15
Number of result at second polling location = 3r - 4
Need to write simplified expression for total number of results at two polling location.
<em>Total number of results at two polling location</em> = Number of result at one polling location + Number of result at second polling location
=> Total number of results at two polling location = (5r + 15) + (3r - 4) = 8r + 11
Hence total number of result at two polling location is represented by expression 8r + 11.
x/3-3 =x/9+3
add 3 to each side
x/3 = x/9 +6
subtract x/9 from each side
x/3 -x/9 = 6
get a common denominator
3/3*x/3 -x/9 = 6
3x/9 -x/9 =6
2x/9 =6
multiply each side by 9/2
x = 54/2
x=27
