Erica walked down a trail into a valley.
inysia [295]

Answer:

Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.

Step-by-step explanation:

It is given that V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.

We need to find the meaning of V(2)=T.

On comparing V(d) and V(2), we get d=2.

Since V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail, therefore V(2) models Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail.

V(2)=T

It means Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.

Casey sells half of his video games. The next day he buys 3 more. He now has 27. How many video games did Casey have at the begi
Llana [10]
To solve this, it is helpful to set up an equation that reductions and additions of the games. The equation would be:

27 = 1/2v + 3

In this equation, v = the original number of video games. The 1/2 signifies Casey selling his games, and the + 3 shows Casey buying three more.

If we subtract 3 from both sides, we see that 1/2v = 24. Finally, we can multiply each side by 2 to isolate the variable, v, and we get v = 48.

Therefore our final answer is 48 video games.

Hope this is helpful!

Consider U = {x|x is a positive integer greater than 1}.
natta225 [31]
Answer: <span><span>{x|x ∈ U and 2x is prime} is an empty set.

</span>Justification:
</span>
U = {x|x is a positive integer greater than 1} = {2, 3, 4, 5, 6, ...}<span>


1) {x|x ∈ U and (1/2) x is prime}

Take x = 4 => (1/2) 4 = 4 / 2 = 2 = prime, so this is not empty.


{x|x ∈ U and 2x is prime}

2) 2x = {4, 6, 8, 10, 12, } so none of them is prime, hence this is an empty set.

3) {x|x ∈ U and (1/2) x can be written as a fraction}

Take any x that is odd. For example x = 3

=> (1/2)x = (1/2)3 = 3/2 which is a fraction, so this is not an empty set.


2) {x|x ∈ U and 2x can be written as a fraction}

Take any value of x, for example x = 7 => 2 = 14, and 14 = 28 / 2 so this is not an empty set.
</span>
