Let C be the number of cats and B be the number of birds.
Each cat has 4 legs while each bird has 2 legs. Thus,
4C + 2B = 22
2B = 22 - 4C
Each cat and each bird has 2 eyes
2C + 2B = 16
Substituting 2B
2C + 22 - 4C = 16
2C = 6
C = 3
2B = 22 - 4(3)
B = 5
2 cats and 5 birds

Answer:
(1.82, 3.17)
Step-by-step explanation:
Given the curve:
y = cosh(x)
we need that the tangent has slope 3. The tangent of a curve in a given point is found with its derivative.
dy/dx = sinh(x) = 3
From the plot of sinh(x), we get:
x ≈ 1.82
Replacing into cosh(x), we get:
y = cosh(1.82) ≈ 3.17
Then, at point (1.82, 3.17) the tangent is 3
