Find The Value Of X When 6-2x = 6x-10x+6. The Value Is

Answers

Answer:

x = 0

Step-by-step explanation:

6 - 2x = 6x - 10x + 6

1. Isolate the variable (x)

Add 2x to both sides

    6 - 2x = 6x - 10x + 6 -> 6 = 6x - 10x + 2x + 6

Subtract 6 from both sides

    6x - 10x + 2x + 6 -> 0 = 6x - 10x + 2x

2. Combine like terms

      0 = 6x - 10x + 2x -> 0 = -2x

3. Solve

Divide both sides by -2

       0 = x

*Note: 0 divided by anything is 0 so 0/-2 is 0

(unless it is 0/0 which equals 1)

PLEASE HURRY A triangle and two of its side lengths are shown in the diagram. Which measurement is closest to the value of x in feet? The diagram show a triangle that has 3.7ft on the left side, 14.3 ft on the right/slanted side, and x at the bottom PLEASE HELP ME

Answers

Answer:

[tex] x = 13.8 ft [/tex]

Step-by-step explanation:

Since it's a right triangle, apply pythagorean theorem.

The formula is given as a² + b² = c²

Where,

a = 3.7 ft

c = 14.3 ft

b = x

Plug in the values into the formula:

[tex] 3.7^2 + x^2 = 14.3^2 [/tex]

[tex] 13.69 + x^2 = 204.49 [/tex]

Subtract 13.68 from both sides

[tex] x^2 = 204.49 - 13.69 [/tex]

[tex] x^2 = 190.8 [/tex]

[tex] \sqrt{x^2} = \sqrt{190.8} [/tex]

[tex] x = 13.8 [/tex] (nearest tenth)

Answer:

C. x=3 and y=−6

Step-by-step explanation:

Step: Solvex−2y=15for x:

x−2y=15

x−2y+2y=15+2y(Add 2y to both sides)

x=2y+15

Step: Substitute2y+15forxin2x+4y=−18:

2x+4y=−18

2(2y+15)+4y=−18

8y+30=−18(Simplify both sides of the equation)

8y+30+−30=−18+−30(Add -30 to both sides)

8y=−48

8y8=−488(Divide both sides by 8)

y=−6

Step: Substitute−6foryinx=2y+15:

x=2y+15

x=(2)(−6)+15

x=3(Simplify both sides of the equation)

Where are the choices?

F(x)= 2x^2-3x-9 G(x)= 4x^2-9 find (f/g) (x)

Answers

This is about division of polynomials.

(f/g)(x) = (x + 1)/(2x + 3)

(f/g) (x) simply means we divide f(x) by g(x)

We are given;

f(x) = 2x² - 3x - 9

g(x) = 4x² - 9

To divide this, let's simplify each function to its factors using the sun-product pattern.

f(x) = 2x² - 3x + 6x - 9

Let's collect like terms;

f(x) = x(2x - 3) + 1(2x - 3)

Rewriting in factored form gives;

f(x) = (x + 1)(2x - 3)

Similarly;

g(x) = 4x² - 9

g(x) = 4x² + 6x - 6x - 9

g(x) = 2x(2x + 3) - 3(2x + 3)

Rewriting in factored form gives;

g(x) = (2x + 3)(2x - 3)

Thus;

(f/g)(x) = ((x + 1)(2x - 3))/((2x + 3)(2x - 3))

(f/g)(x) = (x + 1)/(2x + 3)

Two adults and 9 students cost $50 to attend
the game. If one adult and 8 students cost
$39 how much do adult and student tickets
cost?

Answers

Answer:

The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Let x = number of $3 tickets

Let y = number of $2 tickets

Total = quantity × value

Step-by-step explanation:

x + y = 350                    (equation 1)

3x + 2y = 950                 (equation 2)

Use Substitution Method

Isolate variable x in equation 1

x = 350 – y                     (equation 3)

Substitute equation 3 into equation 2

3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100

Substitute y = 100 into equation 1

x + 100 = 350

x = 250

Answer: 250 $3 tickets and 100 $2 tickets were sold.

HELP ME PLEASE!!!
Because it is always the substance’s density divided by the density of water which is 1 g/cm 3
Because it is always the substance’s density multiplied by the density of water which is 1 g/cm 3
Because specific gravity is the inverse of density
Because these represent the same measurement

Answers

greetings i may be late but yes answer A is correct

Option A is correct, Because it is always the substance’s density divided by the density of water which is 1 g/cm 3

What is Density?

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.

Given that the value of a substance’s specific gravity always the same numerically as its density.

Because density has units and specific gravity is dimensionless, the two are never the same, but they are numerically equal when three conditions are met

Density is measured in grammes per cubic centimetre, grammes per millilitre, or kilogrammes per litre

Density and Specific Gravity are measured at the same temperature

Hence, option A is correct, Because it is always the substance’s density divided by the density of water which is 1 g/cm 3

GET ECKED

Answer:

13

Step-by-step explanation:

This is my first time posting, so sorry if this isn't that clear.

Anyways:

We want to find the x-intercept, and the y-intercept. The x-intercept will always have 0 as y, and the y-intercept will always have 0 as x.

We can find the x-intercept by plugging in 0 as y. So:

x/4+0/12=1

x/4=1

x=4

a=4 (since a is equal to the x-intercept.)

We can find the y intercept by plugging in x as 0:

0/4+y/12=1

y/12=1

y=12

b=12

We can find the slope by using the equation y2-y1/x2-x1, but theres an easier way. Simplifying the original equation x/4+y/12=1 into y=--3x+12 immediatly gets us the slope of -3.

So, 12+4-3=13.

(In case you didn't know how I got y=-3x+12. This is how:

x/4+y/12=1

12(x/4+y/12)=1(12)

3x+y=12

y=-3x+12 )
