Answer:
x = 9
y = 9
Step-by-step explanation:
Given :
Let :
Kenyan French roast coffee = x
Cost per x = $8
Sumatran Coffee = y
Cost per y = $10
x + y = 18 - - - - (1)
8x + 10y = 9 * 18 ;
8x + 10y = 162 - - - - (2)
From (1):
x = 18 - y
Put x = 18 - y in (2)
8(18 - y) + 10y = 162
144 - 8y + 10y = 162
2y = 162 - 144
2y = 18
y = 9
x = 18 - y
x = 18 - 9
x = 9
To figure out if the given relation is a function, we first need to know what a function is:
Function: A relation which relates the element x of set X with a single element of set Y
which means that every value of x can give only one value of y
but we can clearly see from the provided diagram that 5 has 2 possible outputs. Hence, the given relation is NOT a function

Answer: 9
Step-by-step explanation:
Evaluate=
(256 x 3^-5 x 6)^-2 x (3^2/2^3)^4 x 2^28
(256 x 1/243 x 6)^-2 x (3^2/2^3)^4 x 2^28
(256 x 1/243 x 1)^-2 x (3^2/2^3)^4 x 2^28
Multiply=
(256/243)^-2 x (3^2/2^3)^4 x 2^28
Evaluate=
59049/65536 (3^2/2^3)^4 x 2^28
59049/65536 (1/9/2^3)^4 x 2^28
59049/65536 (1/9/8)^4 x 2^28
Divide=
59049/65536 (1/72)^4 x 2^28
Evaluate=
59049/65536 x 1/26873856 x 2^28
59049/65536 x 1/26873856 x 268435456
Multiply=
9
