The answer is 5 and associative property
Answer:
V≈33.51
although I don't have an explanation, sorry, if you look up "how to find the volume of a sphere" on google, it will give you the answer
At every 1.0 unit, boiling point decreases 1.8 unit, which means the slope m = -1.8.
Answer: (7x + 1)(x + 7)
Step-by-step explanation:

Given:
The equation of a line is:

The line is dilated by factor 3.
To find:
The result of dilation.
Solution:
The equation of a line is:

For
,




For
,




Divide both sides by 2.


The given line passes through the two points A(0,5) and B(2,2).
If the line dilated by factor 3 with origin as center of dilation, then

Using this rule, we get


Similarly,


The dilated line passes through the points A'(0,15) and B'(6,6). So, the equation of dilated line is:




Multiply both sides by 2.



Therefore, the equation of the line after the dilation is
.
