  A.  Multiplication with 3×3 matrices

Step-by-step explanation:

Multiplication with real or complex numbers is commutative. Matrix multiplication is not commutative, in general.

Answer:

4 and 5

Step-by-step explanation:

xy = 20

x + y = 9 ⇒ x = 9 - y

y(9 - y) = 20

9y - y² = 20

y² - 9y + 20 = 0

D = ( - 9)² - 4(1)(20) = 81 - 80 = 1

[tex]y_{1}[/tex] = (9 + 1) ÷ 2 = 5

[tex]y_{2}[/tex] = (9 - 1) ÷ 2 = 4

The numbers are 4 and 5

Step-by-step explanation:

Ok. So, when you are dialating, you first step is to determine wether it is bigger or smaller. If the scale factor is more than one, it is an enlargment or getting bigger. If it is less than 1, it is a reduction and getting smaller. Then, it is just math. Lets say that the point is (2, 4) and your scale factor is 2. Multiply 2 times 2 to get 4. Then multiply 4 times 2 to get 8. Your new cordinante is (4, 8).

You are not stupid you can do it!

Answer:

d) No, it is not a proportional relationship because the graph does not go through the origin

Step-by-step explanation:

A proportional relationship has to pass through the origin (0,0)

The y-intercept of the line is 1

Using the slope - intercept relation :

Substituting the values into the relation :

7 = 3(2) + c

7 = 6 + c

c = 7 - 6

c = 1

Therefore, the y-intercept of the line is 1.

Answer:

Step-by-step explanation:

Answer:

|| slope= 1/3

⊥ slope=-3

Step-by-step explanation:

The line is y=1/3x+5

Parallel slopes are the same (think about parallel lines and how they will never intersect- that means that slopes of those lines will never intersect so they have to be the same)

That means that the || slope will be 1/3.

Perpendicular slopes are negative and reciprocal (if you multiply them, they will equal -1)

Which means to solve for the slope perpendicular, use this equation

1/3m=-1

multiply by 3 on both sides

m=-3

So that means the ⊥ slope will be -3.

Answer:

[tex]\frac{1}{3}[/tex] and - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x + 5 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Parallel lines have equal slopes, thus

[tex]m_{parallel}[/tex] = [tex]\frac{1}{3}[/tex]

Give a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3

6 2/7= ?/7

multiply 6 by 7

= 6 2/7= 42/7

add 42 and 2= 44

= 44/7

The given mixed number 6 2/7 expressed as an improper fraction is 44/7.

The given mixed numbers s as follows:

6 2/7

To convert the mixed number 6 2/7 to an improper fraction, we can follow these steps:

Multiply the whole number (6) by the denominator (7).

⇒ 6 x 7 = 42

Add the product from Step 1 to the numerator (2).

⇒ 42 + 2 = 44

Write the sum from Step 2 as the new numerator over the denominator (7).

The improper fraction equivalent of 6 2/7 is 44/7.

Therefore, 6 2/7 expressed as an improper fraction is 44/7.

Answer:

[tex]5110, 5111, 5112[/tex]

Step-by-step explanation:

Let [tex]x=[/tex] first consecutive number

[tex]x + (x+1)+(x+2) = 15333[/tex] ([tex]x[/tex] is the first number, [tex]x+1[/tex] would be the second consecutive number of the sequence, and [tex]x+2[/tex] would be the third)

[tex]3x + 3 = 15333[/tex]

[tex]3x = 15330[/tex]

[tex]x = 5110[/tex]

[tex]x+1 = 5110+1[/tex]

[tex]= 5111[/tex]

[tex]x+2 = 5110 + 2[/tex]

[tex]= 5112[/tex]

[tex]\therefore[/tex] the consecutive numbers that sum up to [tex]15333[/tex] are [tex]5110, 5111,[/tex] and [tex]5112[/tex]

Work Shown:

[tex]\log_{4}(x+10)+\log_{4}(x-2)=\log_{4}(64)\\\\\log_{4}\left((x+10)(x-2)\right)=\log_{4}(64)\\\\(x+10)(x-2)=64\\\\x^2-2x+10x-20=64\\\\x^2-2x+10x-20-64=0\\\\[/tex]

[tex]x^2+8x-84=0\\\\(x+14)(x-6)=0\\\\x+14=0 \ \text{ or } \ x-6=0\\\\x=-14 \ \text{ or } \ x=6\\\\[/tex]

Those are the possible solutions, but plugging x = -14 back into the original equation will lead to an error. So we rule x = -14 out

x = 6 works as a solution however
