Product is defined             [tex]{}[/tex]                                

(ML, MP, NM, PQ, PL, LP, MQ, LQ)        

Product is not defined

(LM, PM, MN, QP, QM, NQ, QN, NL, LN, NP, PN, QL)  

Step-by-step explanation:

During multiplication of matrices, the number of columns of the first matrix must be equal to the number of rows of the second matrix it is multiplying.

Therefore, we can only multiply a m×n matrix to a n×c matrix as follows;

We can only multiply (m×n)·(n×c) → Product is defined

We can not multiply (n×c)·(m×n) →∞ Product is not defined.

Answer:

x = -10/3

Step-by-step explanation:

−4(x−5)=−7x+10

Use the distributive property to multiply −4 by x−5.

−4x+20=−7x+10

Add 7x to both sides.

−4x+20+7x=10

Combine −4x and 7x to get 3x.

3x+20=10

Subtract 20 from 10 to get −10.

3x=−10

Divide both sides by 3.

x = -10/3

Problem 18

Answers:

~P -> Q: "if it is not fall, then the leaves change colors"

~P -> ~Q: "if it is not fall, then the leaves don't change colors"

P -> ~Q: "If it is fall, then the leaves don't change colors"

Q -> ~P: "If the leaves change colors, then it is not fall"

----------

Explanation:

Simply replace each letter with the corresponding definition. We replace each P with "it is fall" and each ~P with "it is not fall". The squiggly line means "not". The same idea applies with Q and ~Q.

==========================================

Problem 19

Answer: Choice A) 134

----------

Explanation:

AB = CD

8x = 4x+24

8x-4x = 24

4x = 24

x = 6

BC = 18x+26

BC = 18*6+26

BC = 134

==========================================

Problem 20

Answer: Choice C) x = 5 and y = 11

----------

Explanation:

(anglePQR)+(angleRQS) = 90

(12x-2)+(6x+2) = 90

18x = 90

x = 5

angle TQU = 90

10y-20 = 90

10y = 110

y = 11

==========================================

Problem 21

Answer:  99

----------

Explanation:

The remote interior angles add to the exterior angle (remote interior angle theorem)

(angle RPQ) + (angle PQR) = angle PRS

(3x-29) + (7x-42) = 6x-3

10x-71 = 6x-3

10x-6x = -3+71

4x = 68

x = 68/4

x = 17

angle PRS = 6x-3

angle PRS = 6*17-3

angle PRS = 99

==========================================

Problem 22

Answer: 116

----------

Explanation:

Refer to the diagram below.

Solve 105+x = 180 to get x = 75

Solve 135+y = 180 to get y = 45

Solve x+y+z = 180 to get z = 60

Solve z+82+p = 180 to get p = 38

Solve p+78+q = 180 to get q = 64

Solve q+r = 180 to get r = 116

==========================================

Problem 23

Answer: B) between 4 and 44 inches

----------

Explanation:

We use a variation of the triangle inequality theorem here.

If p is the missing side length, then

24-20 < p < 24+20

4 < p < 44

So,

4 < XY < 44

The side XY cannot be 4 inches and it cannot be 44 inches either.

==========================================

Problem 24

4 Answers: A, B, C, D

----------

Explanation:

Same idea as problem 23

24-10 < x < 24+10

14 < x < 34

So we'll select values between 14 and 34, excluding each endpoint. Those values are x = 16, 18, 24, 26

In other words, only 12 and 34 are non-answers.

==========================================

Problem 25

Answer: C) 84 degrees

----------

Explanation:

The given exterior angle is 152 degrees

Subtract that from 180 to get the adjacent interior angle 180-152 = 28

Now let's find the missing angle of triangle DEB

D+E+B = 180

28+68+B = 180

96+B = 180

B = 180-96

B = 84

This is the measure of angle DBE

This is also the measure of angle ABC because the two angles are vertical angles.

Vertical angles are always congruent.

Answer:

2 and 4/5

Step-by-step explanation:

If you ate 2/5 of a pizza in 1/7 of an hour then you need to multiply 2/5 by 7

Start by converting 7 into a fraction

7 = 7/1

then multiply the top and bottom of the fractions

2 * 7 = 14

5 * 1 = 5

2/5 * 7/1 = 14/5

Convert 14/5 into a mixed number

14/5 = 2 and 4/5

Answer:

Let us find the slope of the line : x+ 4y = 6

we can write it as 4y = -x +6

y = -(1/4) x + ( 6/4)

slope of the line y= mx + b is m

so here slope = m = -1/4

because we have to find a paraller line so the slope for required line would be same : -1/4

equation of the line having slope m and passing through x1 y1 is :

Y= m( X-x1) + y1

let's plug m= -1/4 x1= -8 and y1 = 5

Y= (-1/4) ( X- -8) + 5

Y= ( -1/4) ( x+8) + 5

Y= (-1/4)( X ) + (-1/4)( 8) + 5

Y= (-1/4) x + 3

Let us now work on second part :

given line is : 2x- 3y = 12

let's write it -3y = -2x +12

y= (-2/-3) x + ( 12/ -3)

Y= ( 2/3) x - 4

slope of this line is 2/3

the required line is perpendicular to it

so the slope of required line = negative resiprocal of this slope =

(-1/ slope of this line ) = -1/( 2/3) = -3/2

Equation of line with slope m= -3/2 and passing through x1= 2 and y1 = 6 is :

Y= m( X-x1) + y1

Y= ( -3/2) ( X- 2) + 6

Y= (-3/2) X - 2(-3/2) + 6

Y= ( -3/2 ) X + 9

Answer : for part 1 : Y= ( 2/3) x - 4

Answer for part 2 : Y= ( -3/2 ) X + 9

Answer:

Step-by-step explanation:

Answer:

( g − f ) ( a ) = g ( a ) − f ( a )

( g −f ) ( a ) = g ( a ) − f ( a )

= − 3 a − 3 − a 2 − 5

= − a 2 − 3a − 8

Step-by-step explanation:

After calculating, the value of (g f) (t) is ( - 4t + 13).

A relation between a set of inputs having one output each is called a function.

Given that;

The functions are,

⇒ g(t) = -2t + 3 and f (t) = 2t - 5

So, The value of function (g f) (t) is find as;

⇒ (g f) (t) = g (f (t))

             = g (2t - 5)

             = - 2 (2t - 5) + 3

             = - 4t + 10 + 3

             = - 4t + 13

Giant Pandas are big creatures that live in south central China. In Sichuan, Shaanxi and Gansu provinces in mountain ranges. They live there because they get heat stress if the temperature rises 25 degrees Celsius (77 F). “They have to live at temperatures below that to stay healthy,” Spotila said. “In nature, they actively seek out cool areas (micro habitats) in summer and move to higher elevations to avoid heat.”

The domain is the set of values for which the given function is defined. The domain of the given function is 0≤x≤7.5. The correct option is B.

The domain is the set of values for which the given function is defined.

The range is the set of all values which the given function can output.

Given that function b model the bagel inventory, b(x), after x hours of opening, and it is given as,

b(x) = 75 - 10x

Now, the domain of the function is the values that x can take in the function. Since x represents the number of hours after opening, therefore, it can not be negative and must start with zero.

Further, since the inventory or the total number of bagels that the shop has is 75, therefore, they can not sell more than that, and at some point, the inventory will become zero. Therefore, we can write,

75 - 10x = 0

-10x = -75

10x = 75

x = 75 /10

x = 7.5 hours

Hence, the domain of the given function is 0≤x≤7.5.

edge 2020

Answer:

50

Step-by-step explanation:

Let the number of orders required be x

Fund raiser A , 1.50 for each other plus bonus of 75

for x orders, we have 1.50 * x = 1.50x

Add the bonus = 1.50x + 75

Fund raiser B, $3 for each other , no bonus

Total from fund raiser B is 3 * x = 3x

So to make them equal, we ensure that e equate both values;

3x = 1.5x + 75

3x -1.5x = 75

1.5x = 75

x = 75/1.5

x = 50

50 orders will make both funds equal
