Answer:
(C)81
Step-by-step explanation:
Total Number of Students =300
Percentage who had cats, n(C) = 40%
Percentage who had both cats and dogs , 
= 12%
Percentage who had neither cats nor dogs, 
=45%
Now:
Universal Set, 
Therefore:
Number of Students who had dogs
=27% of 300
=81
75 / 100 ( divided both numbers by 5 )
= 15 / 20 ( divided both numbers by 5 again )
= 3 / 4 Answer
Answer:
Graph y≤150−x (shading down)
Graph y≥120− 7/11x (shading up)
Step-by-step explanation:

Answer:
x^2 = 25 x = 5, -5
2x^2 = 98 x = 7, -7
x^2 + 64 = 0 x = 8i, -8i
9x^2 - 16 = 0 x = 4/3, -4/3
x^2 + 9 = 25 x = 4, -4
(x-2)^2 = 25 x = 7, -3
(x-2)^2 +9 = 25 x = 6, -2
4(x-2)^2 +9 = 25 x = 4, 0
