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>

Answer:
x = 2.66666667
Step-by-step explanation:
3x + 4 = 12
- 4 = - 4
3x = 8
3x / 3 = 8 / 3
x = 2.66666667
can i be brainiest...
The answer is 5, the 2 are disqualified and 5 remains
Area of the label is calculated as diameter*PI*height
So if height of tomato can is 3 times the can of tuna: hTOM=3*hTUNA
Diameter of a tomato can is three times smaller so: dTOM=dTUNA÷3
so Area of a tomato can label= A=(dTUNA÷3)*PI*3*hTUNA
A=dTUNA*PI*hTUNA
and the area of a tuna can label=
A=dTUNA*PI*hTUNA
So, the label areas are the same.
