Nat2105 [25]

Answer:

2.50x+1.75y<=200

Step-by-step explanation:

Consider the data

Total amount of money available $200

Cost of cedar is $2.50 per feet. The the cost of pine $1.75 per feet

x=# of feet of cedar brought

y=# of feet of pine brought

As the cost of cedar wood is $2.50 and x is the # of feet of cedar brought, so the total cost of # of the wood is $2.50x

As the cost of pine is $1.75 and y is the # of feet of pine brought, so the total cost of # of the wood is $1.75y

The total cost of the # of cedar and pine woods together is

$2.50x+$1.75y

And the total amount available is 200, and it doesn't exceed so

$2.50x+$1.75y<= 200

amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
68&100\\
8&x
\end{array}\implies \cfrac{68}{8}=\cfrac{100}{x}$

Eddi Din [679]

Answer:

$\boxed{(f.g)(x) = 3 {x}^{3} - 15 {x}^{2} - 27x}$

Given:

$f(x) = x + 2 \\ \\ g(x) = 3x + 5$

To Find:

$(f.g)(x) = f(x) \times g(x)$

Step-by-step explanation:

$= > f(x) \times g(x) = (3x)( {x}^{2} - 5x - 9) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (3x \times {x}^{2} ) - (3x \times 5x) - (3x \times 9)\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 {x}^{3} - 15 {x}^{2} - 27x$
