Answer? I’m confused

Answer:

x=4

Step-by-step explanation:

First, you need to isolate the variable and constant terms. So, we need to get rid of 36. To do this, we need to take away 36. Now, we have to do this on the other side. 64-36 is 28. Now, the equation is 7x=28.

To isolate the variable, you divide by 7. Again, do this on the other side. 28/7 is 4. Now we have x=4.

Therefore, the correct answer is 4!

Answer: (b-20)/4

Step-by-step explanation: Liam has b beads. He gives 20 to his sister. That means he has b-20 left. He uses the remaining beads to make four equal necklaces. That means he has (b-20)/4 beads on each necklace.

Answer: 15cm by 20cm

3cm by 4cm

9cm by 12cm

Step-by-step explanation:

From the question, we are informed that a 12 cm by 16 cm painting hangs in a museum. We are given several options and told to choose the paintings' dimensions that are proportional to the original painting. This will be:

12cm by 16cm when divided by 4 gives 3cm by 4cm. This means that we have to look out for the options that are in the ratio 3:4.

A. 6 cm by 12 cm

6cm by 12cm reduced to lowest term gives 1:2

B. 15 cm by 20 cm

15cm by 20cm reduced to lowest term gives 3:4

C. 3 cm by 4 cm

D.6 cm by 9 cm

6cm by 9cm reduced to lowest term gives 2:3.

E. 9 cm by 12 cm

9cm by 12cm reduced to lowest term gives 3:4.

Therefore the correct options are:

15cm by 20cm

3cm by 4cm

9cm by 12cm

Responder:

57288.35 kN

Explicación paso a paso:

Paso uno:

datos dados

diámetro del tubo de entrada = 2 cm = 0.02 m

área = πd ^ 2/4

área = 3.142 * 0.02 ^ 2/4

área = 0.0003142m ^ 2

A1 = 3.14 * 10 ^ -4 m ^ 2

diámetro del pistón de salida = 32cm

masa del coche = 1800 kg

peso del coche = 1800 * 10 = 18000N

carga F2 = 18000N

Segundo paso:

Se requiere la presión aplicada P2

Aplicando la ecuación de presión para un fluido incompresible tenemos

P1 = F2 / A1

P1 = 18000 / 0,0003142

P1 = 57288351.36

P1 = 57288.35 kN

Answer:

The correct answer is:

The graph will be the same width as the parent graph f(x) = x², but the vertex has been shifted to (1, 2).

Step-by-step explanation:

Since the value of a, the coefficient of x², is 1, this means the graph has not been stretched or shrunk. However, since the function is different than f(x)=x², we know that the vertex is not at (0, 0). We can write the function in vertex form to find the new vertex.

To write the function in vertex form, we find the value of b/2. The value of b in this function is -2; -2/2 = -1. We then square this: (-1)² = 1. This is what we add and subtract to the function (we must do both to preserve equality), giving us:

f(x) = x²-2x+1+3-1

The first three terms of this function can be written as the square (x+(b/2))²; this is (x-1)², and gives us f(x) = (x-1)²+3-1. Combining like terms, we have:

f(x) = (x-1)²+2

This is vertex form, f(x) = a(x-h)²+k, where (h, k) is the vertex. This means the vertex is at (1, 2) instead of (0, 0).

Answer:

Step-by-step explanation:

-5n-3(1+2n)= -25

-5n-3-6n= -25            Distributive property (-3*1) and (-3*2n)

-11n-3= -25                 -5n-6n = -11n

    +3    +3                  Add 3 to both sides to leave n alone

-11n= -25                    

-----   -----                    Divide by -11 on both sides to get n alone.

-11     -11

n= -2.2727272....

Answer:

The function [tex]f(x)=x^3+\mathbf{1}x^2-\mathbf{17}x+\mathbf{15}[/tex]

Step-by-step explanation:

We have the polynomial having zeros 1,3,-5

We can write them as:

x=1,x=3,x=-5

or

x-1=0, x-3=0,x+5=0

Multiplying all terms:

[tex](x-1)(x-3)(x+5)\\=(x(x-3)-1(x-3))(x+5)\\=(x^2-3x-1x+3)(x+5)\\=(x^2-4x+3)(x+5)\\=(x^2-4x+3)+5(x^2-4x+3)\\=^3-4x^2+3x+5x^2-20x+15\\=x^3-4x^2+5x^2+3x-20x+15\\=x^3+x^2-17x+15[/tex]

So, The function [tex]f(x)=x^3+\mathbf{1}x^2-\mathbf{17}x+\mathbf{15}[/tex]
