12x -20=n (3x-5)

I need help I don’t get it please help me.

Answers

Answer:

The value of n = 4 and  

The value of x = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Method I:

As given, 12x -20=n (3x-5)      .........(1)

Firstly , take 12x - 20

As 12x - 20 can be written as 4(3x - 5)

∴ equation (1) becomes

4(3x - 5) = n (3x-5)

Divide the equation by (3x-5) , we get

4 = n

Method II:

As given, 12x -20=n (3x-5)

⇒12x - 20 = 3nx - 5n

⇒12x - 3nx = 20 - 5n

⇒3x(4 - n) = 5( 4 - n)

Divide the equation by (4-n) , we get

3x = 5

⇒ x = [tex]\frac{5}{3}[/tex]

∴ we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

Now, check that value of n and x satisfies the equation or not

12([tex]\frac{5}{3}[/tex]) - 20 = 4( 3([tex]\frac{5}{3}[/tex]) - 5)

⇒4(5) - 20 = 4(5 - 5)

⇒20 - 20 = 4(0)

⇒ 0 = 0

Hence , we get

The values of x and n satisfies the equation

so, we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

What single decimal multiplier would you use to decrease by 14% followed by a 9% decrease?

Answers

Answer:

the single decimal multiplier is 0.7826

Step-by-step explanation:

The computation of the single decimal multiplier is given below:

Given that

It is reduced by 14% that followed by 9% decrease

So according to this, the following calculation is required

= (1 - 0.14) × (1 - 0.09)

= 0.86 × 0.91

= 0.7826

Hence, the single decimal multiplier is 0.7826

What is trigonometry?

Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine, cosine, and tangents are their names and acronyms (tan).

Given:

Sinx = 2 / 5  and  tan(x) > 0,

Calculate the value of tan x as shown below,

B² = 5² - 2²  (Using Pythagoras theorem)

B² = 25 - 4

B = √21

Hence, Tan x = 2 / √21

Calculate the value of Sin 2x as shown below,

Sin2x = 2 Tan x / (1 + tan² x)

Sin2x = 2 × 2 / √21 / (1 + (2 / √21)²)

Sin2x = 4 / √21 / (1 + 4 / 21)

Sin2x = 4 / √ 21 / (25 / 21)

Sin2x = 4 √21 / 25

Thus, the value of Sin2x  is 4 √21 / 25.

Identify the zeros of each function. y=(x-7)^2

Answers

9514 1404 393

Answer:

  x = 7 (multiplicity 2)

Step-by-step explanation:

When the function is written in factored form, the zeros are the values of the variable that make the factors zero.

  y = (x -7)(x -7)

The values x = 7 and x = 7 will make the factors zero. The zero is said to be x=7 with multiplicity 2.

__

On the graph, the zeros are the x-intercepts (where y=0). The graph only touches the x-axis, but does not cross. With some experience, you can recognize that this is a zero with even multiplicity (2).

a = 180-120

a = 60

a = b = 60

This is because they are corresponding angles and corresponding angles are equal

c = 120

This is because they are alternate exterior angles and alternate exterior angles are equal

solve using substitution
-5x+7y=-5
y=-5
x=?

Answers

So if you solve for x using the first equation, you get: x = 5y - 5.

From there you can plug that into the second equation which would give you:

7y-5y+5=-23

Simplifying from that point, you get y = -9.

Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.

Manufacturing a company is designing a new rectangular shipping box that must have a

volume of 24 cubic inches. The company has created a box with a width that is 2 inches less

than its length. The height is 5 inches greater than the length. What are the dimensions?

Answers

Answer:

3in by 1in by 8in

Step-by-step explanation:

Volume of the box = Length × Width × Height

Given

Volume = 24in³

If the width is 2inhes less than the length

W = L-2... 2

Also if the height is 5 inches greater than the length, then;

H = L+5 ... 3

Substitite 2 and 3 into the formula.

V= LBH

24 = L(L+5)(L-2)

24 = L(L²+3L-10)

24 = L³+3L²-10L

L³+3L²-10L-24 =0

Factorize

The factored form is

(L+2)(L²+L−12) = 0

L²+L-12 = 0

L²+4L-3L-12 = 0

L(L+4)-3(L+4) = 0

(L+4) = 0 and L-3 = 0

L = 3in

W = L-2

W = 3-2

L = 1in

H = L+5

H=3+5

H = 8in

Hence the dimension is 3in by 1in by 8in
