X = 116

Step-by-step explanation:

Total heptagon angle = 900

124 + 120 + 122 + 136 + 144 + 138 = 784

900 - 784 = 116

A dilation centered at the origin is applied to the line y = 3x + 5.
SOVA2 [1]

Answer:

"The question cannot be answered without knowing the scale factor."

Step-by-step explanation:

<u>The complete question:</u>

<em>A dilation centered at the origin is applied to the line y = 3x + 5.  What is true about the image of the line?</em>

  • <em>It is the same line. </em>
  • <em> It is another line parallel to y = 3x + 5. </em>
  • <em> The image is not a line. </em>
  • <em> The question cannot be answered without knowing the scale factor.</em>

<em />

A dilation, center at origin, with a scale factor of "k", will have a rule:

(x,y) = (kx,ky)

This basically means that the image after dilation will have the points kx and ky respectively.

If k ≠ 1, this means the image is parallel to the line y = 3x + 5

If k = 1, this means the image is same, it coincides with the line y = 3x + 5

<u><em>Thus, the scale factor is really important and we can't say anything about this dilation since scale factor isn't known.</em></u>

Korolek [52]

Answer:

Step-by-step explanation:

Given

- 2 < n + 3 < 4 ( subtract 3 from each interval )

- 5 < n < 1

This indicates that n ≠ - 5, 1 but all values in between, that is

n = - 4, - 3, - 2, - 1, 0 ← possible values of n
