Answer:
The three best can be chosen and ranked in 336 ways.
Step-by-step explanation:
Since you are asked to list the movies in order of preference, the order is important, as a higher order leads to a higher preference. This means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
If you saw eight movies this year, in how many ways can the three best be chosen and ranked?
[tex]P_{(8,3)} = \frac{8!}{(8-3)!} = 336[/tex]
The three best can be chosen and ranked in 336 ways.

Answer: Second option, 2^2x+6=2^6
Step-by-step explanation:
You can simplify 4^x+3 by making the 4 into 2^2. By doing this you also multiply the current powers of 4 by 2, giving you (x+3) • 2, furthermore, 2^2x+6.
64 is a power of 2, so just multiply 2 by itself until you get the number you’re looking for and count how many times you do it. Or just type each option, like 2^4, 2^6 into the calculator until you find it.

A carpenter uses two different types of paint in his work, X-Brand and Y-Brand (represented by the x and y variables respectively in the system of equations below). The system of equations represents the total cost and amount of paint he purchased for a client. Determine the cost, in dollars, of the X-Brand.
2x+5y=6
−x+2y=−3
Answer
$3
Step-by-step explanation:
To find the x value, you want to cancel out the y terms in the equations. To do so, multiply (2x+5y=6) by 2, and (-x+2y=-3) by -5. This gives you
4x+10y=12
5x-10y=15
You can then cancel out the y terms and add the other terms from the 2 equations together to make
9x=27
You then divide 27 by 9 to get 3 as the value for x.
