Answer:

The answer is  [tex]y^2+2y+1[/tex]

Explanation:

- Properties of Exponent -

[tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

Our a is y+1

Our m is 5

Our n is 3

[tex]\frac{(y+1)^5}{(y+1)^3}=(y+1)^{5-3}\\(y+1)^2[/tex]

- Multiply The Polynomial -

As for the Quadratic Polynomial and being squared, we use the following formula:

[tex](x+y)^2=x^2+2xy+y^2[/tex]

Our x is y

Our y is 1

Thus,

[tex](y+1)^2=y^2+2(y)(1)+1^2\\(y+1)^2=y^2+2y+1[/tex]

As our simplified, multiplied form is [tex]y^2+2y+1[/tex]

We know that four snacks and three movie tickets cost $40 dollars, and when you take away 2 snacks but still keep the tickets, its $32.

2 snacks= $8

What i did to find the cost of each ticket is I divided 8 by 2 (8/2) and ended getting $4

1 snack= $4

Now to find the cost of each ticket, i divided 2 snacks ($8) and got this equation:

32 - 8= 24

3 tickets= $24

Now to find the amount for each ticket, i divided 24 by 3 (24/3) and got the answer:

1 ticket= $8

Therefore, snacks are $4 and movie tickets are $8

Thank you! Btw can i please get brainly :3

Step-by-step explanation:

Answer:

The difference $2.733.30

Step-by-step explanation:

Let the total money be x

The remaining money will be (x-1400)

40% of this on a bed

= 40/100 (x-1400)

= 0.4(x-1400)

cost of bed is 25% of x

Thus;

0.4(x-1400) = 25/100 * x

0.4(x-1400) = 0.25x

0.4x - 560 = 0.25x

0.4x-0.25x = 560

= 0.15x = 560

x = 560/0.15

So the difference between the tv and. bed, will be ;

560/0.15 - 1400

= (560-210)/0.15 = $2,333.33

Answer:

[tex]x=12(\sqrt2-1)[/tex]

Step-by-step explanation:

The given equation is :

[tex]\sqrt{2} x-7+x=5[/tex]

Add 7 to both sides of the equation.

[tex]\sqrt{2} x-7+x+7=5+7\\\\\sqrt{2} x+x=12[/tex]

Taking x common from both sides of the equation.

[tex]x(\sqrt{2} +1)=12\\\\x=\dfrac{12}{\sqrt2+1}[/tex]

Multiplying both numerator and denominator by [tex]\sqrt2-1[/tex]

[tex]x=\dfrac{12}{\sqrt2+1}\times \dfrac{\sqrt2-1}{\sqrt2-1}\\\\=\dfrac{12(\sqrt2-1)}{2-1}\\\\=12(\sqrt2-1)[/tex]

Hence, the value of x is [tex]12(\sqrt2-1)[/tex].

Answer:

1) £2 = €2.32

£5 = €5.80

£50 = €58

2) The graph will be a straight line

3) (0, 0)

4) Label the independent variable, £ on the x-axis and dependent variable € on the y-axis

Step-by-step explanation:

1) The given conversion factors is £1 = €1.16

Therefore;

£2 = 2 × €1.16 = €2.32

£2 = €2.32

£5 = 5 × €1.16 = €5.80

£5 = €5.80

£50 = 50 × €1.16 = €58

£50 = €58

2) The shape of the plot of the directly proportional currencies graph will be a straight line

3) Given that the £ is directly proportional to the € and that the value of the € can be found directly by multiplying the amount in £ by 1.16, without the addition of a constant, the graph crosses the axes at the origin (0, 0)

4) The y-axes which is the dependent variable should be labelled €, while the x-axis which is the independent variable should be labelled £

Answer:

When x=2, both expressions have a value of 18.

The expressions have equivalent values for any value of x.

The expressions have equivalent values if x=8

Step-by-step explanation:

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply. 7 x + 4 and 3 x + 5 + 4 x minus 1

When x = 2, both expressions have a value of 18.

7x + 4

= 7(2) + 4

= 14 + 4

= 18

3x + 5 + 4x - 1

3(2) + 5 + 4(2) - 1

6 + 5 + 8 - 1

= 18

The expressions are only equivalent for x = 4 and x = 6.

• This is not true because the expression is also equivalent for x = 2

The expressions are only equivalent when evaluated with even values.

When x = 1

7x + 4

7(1) + 4

= 7 + 4

= 11

3x + 5 + 4x - 1

3(1) + 5 + 4(1) - 1

3 + 5 + 4 - 1

= 11

The expressions have equivalent values for any value of x.

Yes, it has an equivalent value at any value of x

The expressions should have been evaluated with one odd value and one even value.

When x = 0, the first expression has a value of 4 and the second expression has a value of 5.

7x + 4

7(0) + 4

= 0 + 4

= 4

3x + 5 + 4x - 1

3(0) + 5 + 4(0) - 1

0 + 5 + 0 -1

= 4

The expressions have equivalent values if x = 8.

7x + 4

7(8) + 4

56 + 4

= 60

3x + 5 + 4x - 1

3(8) + 5 + 4(8) - 1

24 + 5 + 32 - 1

= 60

Answer:

1,4,7

Step-by-step explanation:

Responder:

$ 131.25

Explicación paso a paso:

Dado que :

Importe pagado tras sucesivos descuentos del 10% y 20%

Sea el costo original = x

Importe final tras ambos descuentos = 94,5

Primer descuento = (1 - 0.1) x = 0.9x

Segundo descuento: (1 - 0.2) de 0.9x = 0.8 de 0.9x = 94.5

Es decir ; 0,8 * 0,9x = 94,50

0,72x = 94,50

Dividir ambos lados por 0,72

0,72x / 0,72 = 94,50 / 0,72

x = 131,25

Por lo tanto, precio original = $ 131.25

Answer:

18 square centimeters

Step-by-step explanation:

To find the area of a rectangle follow the formula, A=lw. Where A is the area, l is the length, and w is the width. So to find the area plug the dimensions into the formula. This would be A=6 x 3, which equals 18. Therefore the answer is 18 centimeters squared.

Answer:

9 cm

Step-by-step explanation:

Area is length x width

3 cm x 3 cm = 9 cm

But if you are doing the problem from the picture it is

A = 6 cm x 3 cm

= 18 cm

Answer:

The number of clay flower pots = x = 19

The number of ceramic flower pots = y = 16

Step-by-step explanation:

Let

The number of clay flower pots = x

The number of ceramic flower pots = y

Tara bought 35 flower pots

= x + y = 35

x = 35 - y

The gardening store sells clay flower pots, which hold 2 litres of dirt, and ceramic flower pots, which hold 7 litres. Tara bought 35 flower pots, which will hold a total of 150 litres of dirt.

Hence:

2x + 7y = 150.... Equation 2

Substitute 35 - y for x in Equation 2

2 (35 - y) + 7y = 150

70 - 2y + 7y = 150

-2y + 7y = 150 - 70

5y = 80

y = 80/5

y = 16 flower pots

x = 35 - y

x = 35 - 16

x = 19 flower pots

The number of clay flower pots = x = 19

The number of ceramic flower pots = y = 16

Answer:

The number of clay flower pots = 19

The number of ceramic flower pots = 16

Step-by-step explanation:

Answer:

c = 88

Step-by-step explanation:

c = 88

Answer:

0.857 weeks

Step-by-step explanation:

Using the information provided we can create the following equations for the total amount Mallory (M) and Aimee (A) will save after x number of weeks...

M = 35 + 15x

A = 5 + 50x

Now we would need to make both of these equations equal one another and solve for x to calculate after how many week both Aimee and Mallory will have saved the same amount of money

35 + 15x = 5 + 50x  ... subtract 5 and 15x from both sides

30 = 35x  ... divide both sides by 35

[tex]\frac{30}{35}[/tex] or 0.857 = x

Finally, we can see that after 0.857 weeks both Mallory and Aimee will have saved the same amount of money.

*** The process provided is correct but I believe that the actual values for Aimees savings should be $50 and plans to save $5 a week, this would make the final result 1.5 weeks which would make more sense***

Answer:

multiply -7 by 6x and then multiply-7 by 7

-7(6x)-7(7)

-42x-49=-133

+49. +49

the 49 cancel out

-42x=-84

divide both sides by -42

-42x/-42=-84/-42

the -42 cancel out

leaving x=2 the negatives cancel out making it positive

Answer:

k = 4

Step-by-step explanation:

The formula for binomial probability distribution is;

P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)

Where C(n, k) is the number of possible ways that n number of people choose k.

While p is probability of success

In this question, 20 children want to choose from 4 toys namely tricycle, blocks, a train set, and puzzles.

This means that from binomial probability distribution formula, n = 20 and k = 4.

Given:

Point A (4, -3) is translated 3 units horizontally and -5 units vertically, rotated 90° clockwise, reflected over the x-axis, and dilated by a factor of 5.

To find:

The rule and coordinates of A'.

Solution:

Let a point be P(x,y).

If a point translated 3 units horizontally and -5 units vertically, then

[tex]P(x,y)\to P_1(x+3,y-5)[/tex]

Then, rotated 90° clockwise.

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

[tex]P_1(x+3,y-5)\to P_2(y-5,-(x+3))[/tex]

Then, reflected over the x-axis.

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

[tex]P_2(y-5,-(x+3))\to P_3(y-5,x+3)[/tex]

Dilated by a factor of 5.

[tex](x,y)\to (5x,5y)[/tex]

[tex]P_3(y-5,x+3)\to P'(5(y-5),5(x+3))[/tex]

[tex]P_3(y-5,x+3)\to P'(5y-25,5x+15)[/tex]

So, the rule of transformation is

[tex](x,y)\to (5y-25,5x+15)[/tex]

We have a point A(4,-3). So, put x=4 and y=-3.

[tex]A(x,y)\to A'(5(-3)-25,5(4)+15)[/tex]

[tex]A(x,y)\to A'(-15-25,20+15)[/tex]

[tex]A(x,y)\to A'(-40,35)[/tex]

Therefore, the coordinate of point A' are (-40,35).
