What is the multiplicative inverse of 156

State of the given functions are inverses. Part 3. NO LINKS!!!!

Effectus [21]

Answer:

9.

h(x)=-x-1

let y =-x-1

interchanging role of x & y

x=-y-1

y=-x-1

h-¹(x)=-x-1

again

f(x)=(2-3x)/2

let

y=(2-3x)/2

interchanging role of x & y

x=(2-3y)/2

2x-2=-3y

y=(2-2x)/3

f-¹(x)=(2-2x)/3

Given function are not inverse of each other.

10.

f(x)=-x+3

let y=-x+3

interchanging role of x & y

x=-y+3

y=3-x

f-¹(x)=-x+3

equal to g(x)=-x+3

Given function are inverse of each other.

Suppose that two players, R and C, write down letters of the alphabet. If both write vowels or both write consonants, then th

vladimir2022 [97]

Answer:

-0.075

Step-by-step explanation:

[Player R, Player C] cases & outcomes :-

(Vowel, Vowel) = (0,0)
(Consonant, Consonant) = (0,0)
(Vowel, Consonant) = (6,-6)
(Consonant, Vowel) = (-5,5)

Prob (R chooses consonant) = 75% = 0.75
Prob (R chooses vowel) = 1 - 0.75 = 0.25
Prob (C chooses vowel) = 30% = 0.30
Prob (C chooses consonant) = 1 - 0.30 = 0.70

Average Loss of R = Expected value of : he choses consonant & C choses vowel; he chooses vowel & C choses consonant

= (0.75)(0.30)(-5) + (0.25)(0.70)(6)

-1.125 + 1.05

= -0.075

In exercises 8-10, write a system of linear equations that has the ordered pair as its solution. (-6, -2)

Anika [276]

Answer:

(8) $x + y = -8$ and $2x - y = -10$

(9) $3x - y = -54$ and $4x + y = -30$

(10) $x + y = 2$ and $x - y = 2$

Step-by-step explanation:

Given [Missing from the question]

$(8).\ (-6,-2)\ \\ (9).\ (-12,18)\ \\ (10).\ (2,0)$

Required

Write a system of linear equations

The solutions to this question is open and have different solutions

Solving (8) (-6,-2)

Let the equations be: x + y and 2x - y

$x + y = -6 - 2$

$x + y = -8$ --- (1)

$2x - y = 2 * (-6) - (-2)$

$2x - y = -10$ -- (2)

So, the equations are:

$x + y = -8$ and $2x - y = -10$

Solving (9) (-12, 18)

Let the equations be: 3x - y and 4x + y

$3x - y = 3 *(-12) - 18$

$3x - y = -54$

$4x + y = 4 * (-12) + 18$

$4x + y = -30$

So, the equations are:

$3x - y = -54$ and $4x + y = -30$

Solving (9): (2,0)

Let the equations be: x + y and x - y

$x + y = 2 + 0$

$x + y = 2$

$x - y = 2 - 0$

$x - y = 2$

So, the equations are:

$x + y = 2$ and $x - y = 2$

-2/3 is a rational number
0.1111.... =1/9 - rational number

-2/3*1/5= -2/15 rational

1/9*1/5=1/45 rational
correct answer A and D

π and √11 are irrational numbers, and when they are multiplied by rational number, they will give irrational number.
