((−3)(2))(2)−(−1)(3)+(3)(3)(2)−(2)(−1)(3)

=(−6)(2)−(−1)(3)+(3)(3)(2)−(2)(−1)(3)

=−12−(−1)(3)+(3)(3)(2)−(2)(−1)(3)=−12−(−3)+(3)(3)(2)−(2)(−1)(3)

=−9+(3)(3)(2)−(2)(−1)(3)

=−9+(9)(2)−(2)(−1)(3)

=−9+18−(2)(−1)(3)

=9−(2)(−1)(3)

=9−(−2)(3)

=9−(−6)

=15

Find f(x) and g(x) so the function can be expressed as y = f(g(x)).

DanielleElmas [232]

$\bf \begin{cases}
f(x)=\cfrac{8}{x}+4\\\\
g(x)=x^2
\end{cases}\qquad f(\ g(x)\ )=\cfrac{8}{\underline{g(x)}}+4\implies f(\ g(x)\ )=\cfrac{8}{\underline{x^2}}+4$

Linda is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.

MA_775_DIABLO [31]

Answer: as company A charges a fix amount $93 for any distance and company B charges variable amount starting from $65.there will be a certain mileage after that the amount charged by company B should be greater than company A.

let for greater than m mileage company A will

charge less than company B.

charge for company A for m mileage= $93

charge for company B for m mileage= $65 + $0.70*m

so,

93 ≤ 65+0.70*m

93-65 ≤ 65+0.70*m -65

28 ≤ 0.70*m

28*10 ≤ 7 *m

280 ≤ 7m

280/7 ≤ 7m/7

40 ≤ m

Ans: greater than 40 mileage Company A will charge less than Company B
