Answer:
=chicken$3
Duck$9.20
Step-by-step explanation:
50c+30d=550
44c+36d=532
add 6 to equalize c
50c+36d=556
50c+42d=538
sutract the two
6d=18
d=3
30*3=90
550-90=460/50=9.2

Answer:
b and c, b and c are same
Step-by-step explanation:
Only a and d can be evaluated using simple substitution.
For a, integral of the square root of (x-1)dx i.e
let y = x-1
dy = dx
It becomes integral square root of ydy, ∫√ydy
which is can easily be evaluated and y is substituted back.
For d, integral of x times the square root of the quantity x squared minus 1
let y= x squared minus 1
then dy = 2xdx
dx = dy/2x
It becomes integral x times square root of y dy/2x
∫x√ydy/2x=∫√ydy/2=1/2∫√ydy which can easily be evaluated and y is substituted back
