What is the slope of a line perpendicular to this line?

multiply by 9

1 ×9 = 9

9×9 = 81

81 ×9 = 729

Answer:

each time, you multiply the number by 9

Step-by-step explanation:

1x9=9

9x9=81

81×9=729

If you wanted to know the next number in the sequence, just multiply 729 by 9 which equals 6561.

hope this helps.

Answer this question by starting at the original point and moving opposite to what the question asks.

Instead of moving down 9 units, starting at (2, -5) move up 9 units.

By doing this, you are now at (2, 4)

Starting at (2,3) move to the left by 4 units.

You end up at ( -2,4)

You can also solve this problem by using addition.

To find the original add/subtract the units from the coordinates (2, -5)

To find the x coordinate: subtract 4 from 2: -2

To find the y coordinate: add 9 to -5: 4

(-2, 4)

Step-by-step explanation:

to make it hopefully better visible :

(2a² + b³)(2a² - b³) = 4a² - b³

let's do the multiplication on the left side :

2a²×2a² - 2a²×b³ + 2a²×b³ - b³×b³ =

= 4a⁴ - b⁶

this is NOT the same as the right side of the original equation 4a² - b³

so, this is NOT an identity.

FYI

(a + b) × (a - b) is always a² - b²

Step-by-step explanation:

Domain = all the values that go into a function

The picture of your graphs is very blurry and I can't see the whole of the last graph (D), but from a process of elimination, I think D is the answer as the domains of the other graphs are:

A:   x ≥ 3

B:   x ≥ 5

C:   x ≤ -3

Answer:

Step-by-step explanation:

g(x)= -x-1 or g(x) = x+1

if g(x) = -x-1

-x-1=2x+4

-x=2x+5

-x/2=x+5

-x/2 -x=5

-x/2-2x/2=5

-x-2x=5

-3x=5

x=5/-3

if g(x) = x+1

x+1=2x+4

x=2x+3

x/2=x+3

x/2-x=3

x/2-2x/2=3

x-2x=3

-x=3

x=3

Step-by-step explanation:

How you can solve this problem is you can divide each number by 3, 18/3 is 6, and 750/3 is 250. So, one chair weighs 6 kilograms and 250 grams.

Fish = F

F + F(.2) = t

Step-by-step explanation:

Answer:

∠ACB = 38°

Step-by-step explanation:

∠ACB is an inscribed angle while arcAB is its intercepted arc

An inscribed angle is equal to half the length of its intercepted arc

Hence, ∠ACB = 1/2 the measure of arc AB

arc AB = 76°

Hence ∠ACB = 1/2 of 76

76/2 = 38

Therefore ∠ACB = 38°

The interior angles of any triangle always sum to 180°.

In the triangle, angles C and D are labeled congruent, so the missing angle has measure

180° - 2 (6x - 5)°

This angle is supplementary to the one labeled (11x + 1)°, which means

180° = (11x + 1)° + (180° - 2 (6x - 5)°)

Solve for x :

180° = (11x + 1)° + 180° - 2 (6x - 5)°

0 = (11x + 1)° - 2 (6x - 5)°

0 = (11x)° + 1° - (12x)° + 10°

(12x - 11x)° = 1° + 10°

x° = 11°

x = 11

The total growth, in inches, of Isabella's plant is [tex]4\frac{1}2[/tex] inches

From the line plot, the total growth can be represented as:

[tex]Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3[/tex]

Evaluate the products

[tex]Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8[/tex]

Evaluate the sum

[tex]Total = \frac{4+4+9+4+15}8[/tex]

Evaluate the numerator

[tex]Total = \frac{36}8[/tex]

Evaluate the quotient

The interquartile range for Group A employees is 1 more than the interquartile range for Group B students is true.

Given

Data represented as a number of hours spent studying by Group A Students:

1, 2, 1, 1, 3, 3, 2, 2, 3

Arranging it in ascending order: 1, 1, 1 ,2, 2, 2, 3, 3, 3,

As a number of terms are odd,

The median will be the middle value of observation.

Which is 2.

The interquartile range (IQR) is the range of values that resides in the middle of the scores.

The Data arranged in ascending order are; (1,1,1,2,2,2,3,3,3).

Median of (1, 1, 1, 2) = 1 [tex]\rm Q_1=1[/tex]

Median of (2, 3, 3, 3) =3 [tex]\rm Q_3=3[/tex]

Interquartile Range = [tex]\rm Q_3-Q_1[/tex] = 3- 1 =2

For Data Set 2,

The Data for group B students are:  3   2 3 2 2 2 1 1 2

Arranging in ascending order: 1,1,2,2,2,2,2,3,3

The total number of observations = 9

Median = 2

Arranging the data as : (1,1,2,2) 2,(2,2,3,3)

Median of (1,1,2,2)= Number of observations is 4 which is even;

[tex]\rm Median = \dfrac{1+2}{2}\\\\Median = \dfrac{3}{2}[/tex]

Median of (2,2,3,3) = [tex]\rm Q_3 =\dfrac{3+2}{2} = \dfrac{5}{2}[/tex]

S = Interquartile Range = [tex]\rm Q_3-Q_1=\dfrac{5}{2}-\dfrac{3}{2}=1[/tex]

The interquartile range for Group A Students =Interquartile range for Group B students + 1.

[tex]\rm D=S_1+1[/tex]

Hence, the interquartile range for Group A employees is 1 more than the interquartile range for Group B students is true.

Answer:

y=3/2x+15

Step-by-step explanation:

Hi there!

We are given that a line passes through the point (-4,9) and has a slope of 3/2

We want to write the equation of this line in slope-intercept form

Slope-intercept form is  y=mx+b, where m is the slope and b is the y intercept

Since we are given the slope of the line already (3/2), we can plug it in as m into the equation.

y=3/2x+b

Now we must solve for b

As the equation passes through the point (-4, 9), it means that the point is a solution to the equation, meaning that it will result in a true statement when you plug its values into the equation

So let's plug the -4 as x and 9 as y into the equation

9=3/2(-4)+b
Multiply

9=-6+b
Add 6 to both sides

15=b
Substitute 15 as b into the equation

y=3/2x+15
