Answer:

x = -7

Step-by-step explanation:

First, we distribute, this gets us -6x+27 = 48-3x. Now, we add 3x to both sides, this gets us -3x+27 = 48. Now, we subtract 27 from both sides. -3x = 21. Now, we divide both sides by -3. This gets us x = -7.

Answer:

15

Step-by-step explanation:

9x - 3 = $\frac{(5x + 1) +19}{2}$

2(9x - 3) = 5x + 1 + 19

18x - 6 = 5x + 20

13x = 26

x = 2

GH = 9(2) - 3 = 15

Answer:

Yes. the relation is a function

Step-by-step explanation:

Here, we want to check if the relation is a function

if a relation is a function, then every x-values (input values) will have one y-value

No two output values (y values) will have a single x value

Looking at the pairs;

It is a function

Although two x values have same y value; 2 and 3 to 8; no two y values have same x value

Hence, the ordered pairs is a function

Imagine an experiment in which one student is selected at random from among all currently enrolled students in this university.

Alex_Xolod [135]

Answer:

$\left \{ x\varepsilon U;x\notin A \right \}$ , $\left \{ x\varepsilon U;x \varepsilon A\cap B \right \}$ , $\left \{ x\varepsilon U;x \notin A, x \varepsilon B \right \}$ , $\left \{ x\varepsilon U;x \notin A, x \notin B \right \}$ , $\left \{ x\varepsilon U;x \varepsilon A \cup B \right \}$ , $\left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B) \right \}$

Step-by-step explanation:

Set refers to the well defined collection of objects.

We can express a set in set-builder form or in roaster form.

Roster form is a mathematical representation of a set that lists all of the elements of the set within the curly bracket, separated by commas.

A set-builder notation is a mathematical representation for describing a set that lists all of the elements of the set by stating the properties that its elements must satisfy.

Let A be the event that the selected student is classified as enrolled in engineering (one of the engineering schools), and let B be the event that the same student is currently enrolled in this class.

Let U denotes the set of all students currently enrolled in the university.

1. $\left \{ x\varepsilon U;x\notin A \right \}$

2. $\left \{ x\varepsilon U;x \varepsilon A\cap B \right \}$

3. $\left \{ x\varepsilon U;x \notin A, x \varepsilon B \right \}$

4. $\left \{ x\varepsilon U;x \notin A, x \notin B \right \}$

5. $\left \{ x\varepsilon U;x \varepsilon A \cup B \right \}$

6. $\left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B) \right \}$
