Geometry!

Answer:

L- 23

P-53

O-28

U-43

H-58

Step-by-step explanation:

For this question you must simply replace N in the equation with the number in every letter for example L is 23 because a = 5 x (4) + 3, thus these are your answers!

Answer:

n=4   a=23

n=10  a=53

n=5   a=28

n=8   a=43

n=11   a=58

I dont know what the letter are for but here ya go.

Hope this Helps your sister! :)

Given:

The vertices of a quadrilateral are v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6).

To find:

The vertices of the image of quadrilateral vwxy after 180° about the origin.

Solution:

If a figure rotated 180° about the origin, then the rule of rotation is

[tex](x,y)\to (-x,-y)[/tex]

Using this rule, we get

[tex]v(-2,-1)\to v'(2,1)[/tex]

[tex]w(-5,-2)\to w'(5,2)[/tex]

[tex]x(-8,-7)\to x'(8,7)[/tex]

[tex]y(1,-6)\to y'(-1,6)[/tex]

Therefore, the vertices of image of quadrilateral vwxy after 180° about the origin are  v'(2,1), w'(5,2), x'(8,7), y'(-1,6).

(15y+x)^2

That’s your answer. I hope i helped!

Answer:

Answers provided below

Step-by-step explanation:

From the simultaneous linear equation, we have the coefficient matrix as;

(3 4 5)

(2 -1 8)

(5 -2 7)

The x-matrix is Dx is given by;

(18 4 5)

(13 -1 8)

(20 -2 7)

Similarly, the y-matrix Dy is given by;

(3 18 5)

(2 13 8)

(5 -20 7)

Also,the z-matrix Dz is given by;

(3 4 18)

(2 -1 13)

(5 -2 -20)

Determinant of the coefficient matrix from online determinant calculator is;

D = 136

Determinant of the x-matrix from online determinant calculator is; Dx = 92

Determinant of the y-matrix from online determinant calculator is; Dy = 696

Determinant of the z-matrix from online determinant calculator is; Dz = 576

From crammers rule;

x = Dx/D = 92/136

y = Dy/D = 696/136

z = Dz/D = 576/136

Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Step-by-step explanation:

The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-

[tex](n-2)\times180^{\circ}[/tex]

Given: The sum of the measures of the interior angles of a polygon is 1920°.

i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]

[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]

But number of sides cannot be in decimal.

Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Answer:

[tex]\huge\boxed{\sf 18 cm\²}[/tex]

Step-by-step explanation:

The figure consists of 2 rectangles.

Rectangle 1 Area:

Length = 5 cm

Width = 2 cm

Area = Length * Width

A = 5 * 2

A = 10 cm²

Rectangle 2 Area:

Length = 4 cm

Width = 2 cm

Area = 2 * 4

A = 8 cm²

Area of the whole figure:

= Rectangle 1 + Rectangle 2

= 10 + 8

= 18 cm²

Answer: n=1,2,3

Step-by-step explanation: if we plug in these numbers 2*1+3*1=5*1 this works. If we do this for 2 then we have 2*2+3*2=10 and 5*2= 10 this also works. The same thing with 3.  2*3+3*3=15     5*3=15

Hope this helps!

Answer:

yay i got the spam answerer reported

Step-by-step explanation:

Answer:

y=-17, x=-8

Step-by-step explanation:

x-9=3x+7

Isolate x for x-9=3x+7;

x-9=3x+7

Add 9 to both sides:

x-9+9=3x+7+9

Simplify;

x=3x+16

Subtract 3x from both sides;

x-3x=3x+16-3x

Simplify;

-2x=16

Divide both sides by -2;

-2x/-2=16/-2

simplify: -2x/-2

=x

Simplify 16/-2:

x=-8

For y=x-9 substitute x=-8;

y=-8-9

Simplify;

y=-17

The solutions to the System of equations are;

y=-17, x=-8

Answer:

y = 10(3)x

Step-by-step explanation:

The exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.

For any function y = f(x), Domain is the set of all possible values of [x] for which [y] exists. Range is the set of all values of [y] that exists for the given domain.

Given is rate of increase of a rabbit's population.

The exponential function that can represent the population of rabbits after [x] years can be written as -

y = 10(3)ˣ

Refer to the graph attached.

Hence, the exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.

Answer:

$33.6

Step-by-step explanation:

24*1.4=33.6

the 1.4 represents the added 40% to find the original price of the sled

Answer:

original price = 40

Step-by-step explanation:

make an equation using the information given in the question, x will represent the original price

x - 0.4x = 24

or

x - 2/5x = 24

solve for x

x - 2/5x = 24

3/5x = 24

x = 40

Answer:

A:

probability of red = 4/16 = 1/4

prob(blue) = 7/16

probability of red, then blue is (1/4)(7/16) = 7/64

B:

probability red = 1/4

probability blue = 7/15

probability of red, then blue = (1/4)(7/15) = 7/60

c) your decision

Step-by-step explanation:

i took the test

The solution is,

A. 7/64 is the probability of selecting a red marble, replacing it, and then selecting a blue marble.

B. 7/60 is the probability of selecting a red marble, setting it aside, and then selecting a blue marble.

C. the answer is no.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given,

There are 4 red marbles.

There are 7 blue marbles.

There are 5 green marbles.

There are 16 marbles in total.

A:

Answer = (probability of selecting a red marble)(probability of selecting a blue marble)

First, the probability of selecting a red marble.

probability of red = 4/16 = 1/4

probability(blue) = 7/16

probability of red, then blue is (1/4)(7/16) = 7/64

B:

Answer = (probability of selecting a red marble)(probability of selecting a blue marble)

First, the probability of selecting a red marble.

probability red = 1/4

probability blue = 7/15

probability of red, then blue = (1/4)(7/15) = 7/60

c) obviously,

7/64 ≠ 7/60

So the answer is no.
