Given two points 
, the slope of the line passing through the two points is
So, in your case, you have
So there are 2 dogs to every 3 cats (put into words)
in order to reach 15 total multiply both 2 and 3 by 3
2x3 = 6
3x3 = 9
so there are 6 dogs and 9 cats
The formula for the volume of a sphere is V=(4/3) (pi) r^3. if r is doubled then you get 2r as the radius and V=(4/3) (pi) * 8r^3 so the volume is eight times bigger than the original r value. if r is tripled the r =3r and (3r)^3 so the volume is 27 times bigger. If r is multiplied by n the radius is nr and (nr)^3 =n^3 r^3, Therefore, the volume is n^3 times bigger than the original.
Okurr I’m just responding so I can answer a question but idk anything so I’m just typing to finish setting up my account..❤️
