For palarell lines, slope are equal.
slope of first line = (y2 - y1)/(x2 - x1) = (-7 - 9)/(-12 - 8) = -16/-20 = 4/5
equation of a line passing through a point is given by: y - y1 = m(x - x1); where (x1, y1) = (-5, -15) and m = 4/5.
Therefore equation of the line is y - (-15) = 4/5(x - (-5))
y + 15 = 4/5(x + 5)

Answer:
Number is two
Step-by-step explanation:
First of all we find the closest factors of 864 which are 32 x 27
Simply them we have
32 x 27 = 2^5 x 3³
So
Next we know that to be aperfect cube, each exponent needs to be equally divided by divisible by 3.
So If we multiply 864 x 2 we get
Then
1728 = 2^6 x 3³
So if we finally
Take the cube root of that is 2²* 3^1 = 4 x 3= 12
So 2² x 3^1
So if we equate the powers we have the answer as 2.
Answer:
Step-by-step explanation:
The radius of a circle is independent of the location of its center, and circles are always similar. Here, therefore, the circles are similar; their shapes are exactly the same. Only the radii differ from one another. The radius of Circle A is 3 and that of Circle B is 9; thus the radii differ by a factor of 3.
