Answer:
(7,-3)
Step-by-step explanation:
y = -3
substitute in the first equation
3x - y^2 = 12
3x - (-3)^2 = 12
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 7
coordinates of intersection (7,-3)
Answer:
The ratio of total puppies to brown puppies is 3 for 1. For every 3 puppies there is 1 brown puppie.
Step-by-step explanation:
In order to find the ratio between the total puppies to brown puppies we need to take the total amount of puppies , that is, the sum of all the puppies and divide it by the number of brown puppies. So we have:
ratio = total amount of puppies/brown puppies
ratio = (3+2+1)/(2) = 6/2 = 3/1
The ratio is for every three puppies we have one brown puppie.
P=2l×2w
130=2l×2(l-9)
130=2l×2l-18
148=4l
37=l
w=l-9
w=37-9
w=28
The width is 28
