In the definition of rational numbers, b cannot equal 0, why?

Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

A rational number Q can be expressed in the form

[tex]\frac{a}{b}[/tex] where a and b can take any integer value except b = 0

This is because it would lead to division by zero which is undefined.

Answer:

D: 2/3x - 13/12 = -5/12x

Step-by-step explanation:

2/3x - 5/6 = -5/12x + 1/4

To simplify, the denominator must be the same. So,

5/6 = 10/12

and 1/4 = 3/12

Then, you move the values to the same side via addition or subtraction.

2/3x (- 10/12 - 3/12) = -5/12x

2/3x - 13/12 = -5/12x

Solve the simultaneous equations:

3a-2b=14
4a+3b=13

Answers

Answer:

Step-by-step explanation:

3a-2b=14 multiply by 3

9a - 6b = 42 (1)

4a+3b=13 multiply by 2

8a +6b = 26 (2)

sum up (1) and (2)

17a = 68

a =4

b=-1

Answer:

a = 4 b = -1

Step-by-step explanation:

13 = 4a - 3b  (1)

14 = 3a + 2b  (2)

(1) x 2

(2) x 3

26 = 8a - 6b   (3)

42 = 9a + 6b   (4)

(3) + (4)

68 = 17a

68/17 = 17a/17

a = 4

Substitute back in to original equation

14 = 3(4) - 2b

14 = 12 - 2b

14 - 12 = 12 -12 - 2b

2 = -2b

Divide by -2 both sides

b = -1

Check

3(4) - 2(-1)

12 + 2 = 14

In how many ways can 3
person study groups be
selected from a class of 25
students?

Answers

There are 2300 ways by which we can select 3 students out of 25 students.                        

What is Combination?

Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.

Here total number of Students = 25

         Number of selection = 3

Now,

Total number of ways by which we can select 3 out of 25  = ²⁵C₃

                                                                                               = 25!/3!.22!

                                                         = 25 X 24 X 23 X 22! / 3X2X1 X 22!

                                                         = 13800 / 6

                                                         = 2300

Thus, there are 2300 ways by which we can select 3 students out of 25 students.

Answers

9514 1404 393

Answer:

  B.  The graph flips over the x-axis

Step-by-step explanation:

When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.

The graph flips over the x-axis.

1. What will happen to the current if the voltage is decreased by one half while the
resistance is held constant? State the relationship of voltage and current based
on your answer.​

Answers

Answer: Current will reduce by half

Step-by-step explanation:

The formula for Current is;

Current = Voltage/ Resistance

Say for instance that Voltage is 5 volts and Resistance is 2 ohms. Current will be;

= 5/2

= 2.5 amps

If Voltage is decreased by one half to 2.5 while resistance is held constant, current becomes;

= 2.5/2

= 1.25 amps

Current went from 2.5 to 1.25 amps.

This shows that current will reduce by half if the voltage is decreased by one half while the  resistance is held constant.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

We have the inequality 2x + 6 > 20.

Now, Subtract 6 from both side we get

2x+ 6 - 6< 20 - 6

2x < 14

Divide both side by 2 we get

2x/2 < 14/2

x< 7
