The domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis.

The range is the set of possible output values, which are shown on the y-axis.

In the given graph, it shows that:

Domain (x-values): All reals

Range (y-values): y ≥ 2

Answers:

Step-by-step explanation:

To see which ordered pairs work in the inequality, substitute the ordered pairs in for the variables. If you get a true statement, this means the pair is a solution to the inequality.

A. 3, 18

-3x + y > 7

-3(3) + 18 > 7

-9 + 18 > 7

9 > 7 Correct :)

3, 18 is a solution to this inequality.

B. -2, -3

-3(-2) + -3 > 7

6 + -3 > 7

3 > 7 Incorrect :(

-2, -3 is not a solution to this inequality.

C. -1, 8

-3(-1) + 8 > 7

3 + 8 > 7

11 > 7 Correct :)

-1, 8 is a solution to this inequality

D. 1, 9

-3(1) + 9 > 7

-3 + 9 > 7

6 > 7 Incorrect :(

1, 9 is not a solution to this inequality.

E. 0, 7

-3(0) + 7 > 7

0 + 7 > 7

7 > 7 Correct :)

0, 7 is a solution to this inequality.

Can someone solve this its probably easy but i dont know

Rzqust [24]

Answer:

Step-by-step explanation:

A={26,30,32,44,48}

B={22,26,34}

A∩B=26

number of elements=1

elements in ξ are {22,24,26,28,30,32,34,36,38,40,42,44,46,48}

number of elements in ξ=14

P(A∩B)=1/14

I can't draw venn diagram but i give hint

A={30,32,44,48}+{26}

B={22,34}+{26}

A∩B={26}

Answer:

Points Q, J and M are not collinear

Step-by-step explanation:

Three points cannot be collinear if they are not coplanar (on the same plane), and M is on a different plane than Q. J is located on both planes.

the population of a type of local dragonfly can be found using an infinite geometric series where a1= 65 and the common ratio is

LiRa [457]

Sum of infinite series of a GS is a1 / (1-r)

so here it is 65 / (1 - 1/6) = 65 / 5/6 = 65*6 / 5 = 78 answer

hus, D satisfying (ABC)DequalsI exists. Why does the expression for D found above also satisfy D(ABC)equalsI, thereby showing

Assoli18 [71]

Complete Question

The complete question is shown on the first uploaded image

Answer:

First Question

Option A is correct

Second Question

Option C is correct

Third Question

$D = A^{-1} * B^{-1} * C^{-1}$

Fourth Question

So substituting for D in (ABC) D = I

$(ABC) * A^{-1} * B^{-1} * C^{-1} = I$

$I = I$

This proof that ABC is invertible

Step-by-step explanation:

From the question we are told that

A , B and C are invertible which means that $A^{-1} , B^{-1}, C^{-1}$ exist

Now

From the question

(ABC) D = I

Where I is an identity matrix

Now when we multiply both sides by $A^{-1}$ we have

$A^{-1} A BCD = A^{-1} * I$

$IBCD = A^{-1}$

Now when we multiply both sides by $B^{-1}$ we have

$B^{-1 } *I BCD = A^{-1} * B^{-1}$

$I CD = A^{-1} * B^{-1}$

Now when we multiply both sides by $C^{-1}$ we have

$C^{-1} * I CD = A^{-1} * B^{-1} * C^{-1}$

$I D = A^{-1} * B^{-1} * C^{-1}$

$D = A^{-1} * B^{-1} * C^{-1}$

So substituting for D in the above equation

$(ABC) * A^{-1} * B^{-1} * C^{-1} = I$

$I = I$

This proof that ABC is invertible
