Find the inverse of f(x)=-3x+3
kolezko [41]
To get the inverse, first off do a quick switch on the variables, and then solve for "y".

\bf f(x)=y=-3x+3\qquad \qquad inverse\implies \boxed{x}=-3\boxed{y}+3
\\\\\\
x-3=-3y\implies \cfrac{x-3}{-3}=y\implies \cfrac{3-x}{3}=y\impliedby f^{-1}(x)

Movies at the rental store are $3.75 each. Snacks and drinks are $1.89 each. Round each amount to the nearest dollar to estimate
Troyanec [42]

The estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C

<h3>Total cost</h3>

This is the summation of all units cost of items or the results of adding all cost(fixed and variable)

Cost of movies = $3.75

= $4.00 to the nearest dollar

Cost of snacks (drinks, popcorn, candy bars) = $1.89 each

= $2.00 to the nearest dollar

Cost to rent 3 movies and buy popcorn, a soda, and a candy bar.

Total cost = (Cost of movies × number of movies) + cost of popcorn + cost of soda + cost of candy bar

= (4 × 3) + 2 + 2 + 2

= 12 + 2 + 2 + 2

= $18

Therefore, the estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C

Please brake down why !
lana66690 [7]

Answer:

D

Step-by-step explanation:

using the rule of radicals

• \sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

simplifying \sqrt{32}

\sqrt{32} = \sqrt{16(2)} = \sqrt{16} × \sqrt{2} = 4\sqrt{2}

\sqrt{32} + 5\sqrt{2}

= 4\sqrt{2} + 5\sqrt{2} = 9\sqrt{2} → D
