Let x be the price for adults and y be the price for children at the restaurant. The total amount paid by the Taylor family is $40.50 and may be expressed as 2x + 3y. That of the Wong family may be expressed as 3x + y and amounts to $38. Thus, the system of linear equation is,
2x + 3y = 40.50
3x + y = 38
The answer therefore is letter C.

Answer:
A
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= 5x³ - 2 + 2x + 1 ← collect like terms
= 5x³ + 2x - 1
Answer:
(fоgоh)(x)=2x³+1
Step-by-step explanation:
Function composition is an operation where two functions, say f(x) and g(x), a new function h(x)=(fоg)(x)=f(g(x)) is generated. In this operation, the function g is applied to the result of the function f. Hence, function f:X→Y and g:Y→Z are joined to form a new function h:X→Z
Given 
(fоgоh)(x)=
=
=
=2x³+1
