At the grocery store, Lily spent m dollars on milk, twice that amount on fruit, and 6 dollars less than 3 times the amount spent
AlladinOne [14]

Answer:

<u>The amount of money Lily had when she left the store, in terms of m, is 86 - 6m</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

m = Milk Lily purchased

2m = Fruit Lily purchased (twice that amount on fruit)

3m - 6 = Bread Lily purchased (6 dollars less than 3 times the amount spent on milk for bread)

Amount of money Lily entered = $ 80

2. How much money did Lily have when she left? Write your answer in terms of m.

Let's write the equation to find out the money left in terms of m, this way:

Money left = 80 - m - 2m - (3m - 6)

Money left = 80 - m - 2m - 3m + 6

Money left = 86 - 6m

<u>The amount of money Lily had when she left the store, in terms of m, is 86 - 6m</u>

A space is totally disconnected if its connected spaces are one-point-sets.Show that a finite Hausdorff space is totally disconn
marysya [2.9K]

Step-by-step explanation:

If X is a finite Hausdorff space then every two points of X can be separated by open neighborhoods. Say the points of X are x_1, x_2, ..., x_n. So there are disjoint open neighborhoods U_{12} and U_2, of x_1 and x_2 respectively (that's the definition of Hausdorff space). There are also open disjoint neighborhoods U_{13} and U_3 of x_1 and x_3 respectively, and disjoint open neighborhoods U_{14} and U_4 of x_1 and x_4, and so on, all the way to disjoint open neighborhoods U_{1n}, and U_n of x_1 and x_n respectively. So U=U_2 \cup U_3 \cup ... \cup U_n has every element of X in it, except for x_1. Since U is union of open sets, it is open, and so U^c, which is the singleton \{ x_1\}, is closed. Therefore every singleton is closed.

Now, remember finite union of closed sets is closed, so \{ x_2\} \cup \{ x_3\} \cup ... \cup \{ x_n\} is closed, and so its complemented, which is \{ x_1\} is open. Therefore every singleton is also open.

That means any two points of X belong to different connected components (since we can express X as the union of the open sets \{ x_1\} \cup \{ x_2,...,x_n\}, so that x_1 is in a different connected component than x_2,...,x_n, and same could be done with any x_i), and so each point is in its own connected component. And so the space is totally disconnected.
