Finding Equations for the Values

The result of the unknown variable x is equivalent to 7

Linear equations are equation that has a leading degree of 1. Given the expression below:

5(3x − 15) + 16 = 5x + 11

Expand the expression

5(3x) - 5(15) + 16 = 5x + 11

15x - 75 + 16 = 5x + 11

15x - 5x - 59 - 11 = 0

10x - 70 = 0

10x = 70

Divide both sides by 10

10x/10 = 70/10

x = 7

Hence the value of x makes the equation true is 7

Answer:

Step-by-step explanation:

Use the coordinates of the given points to find the slope.

difference in y-coordinates = -3 - 6 = -9

difference in x-coordinates = 2 - (-1) = 3

slope = -9/3 = -3

Answer:

(3, -4)

Step-by-step explanation:

For this problem you just need to find the distance between each of the x values and each of the y values.

The difference between -2 and -7 (-7 - -2) is -5, so the x coordinate of point B should be 3 (-2 - -5).

The difference between 2 and -1 (2 - -1) is 3, so the y coordinate of point B should be -4 (-1 - 3).

Hi there!

The two angles are alternate-interior angles, so:
∠A ≅ ∠B

6x + 18 = x + 93

Solve for x. Subtract x from both sides:

5x + 18 = 93

Subtract 18 from both sides:

5x = 75

Divide both sides by 5.

x = 75/5 = 15°

Now, solve for angle B by plugging in this value into the equation.

∠B = 15 + 93 = 108°

The solution of the system of equations is (8, 11).

We know that one of the equations of the system is:

y = x + 3

And the other line passes through the points (3, 1) and (4, 3), then the slope of that line is:

a = (3 - 1)/(4 - 3) = 2

So the line is something like:

y = 2*x + b

To find the value of b, the y-intercept, we can replace the values of one of the points.

I will use (3, 1)

1 = 2*3 + b

1 = 6 + b

1 - 6 = b

-5 = b

So the other line is y = 2x - 5

Then the system of equations is:

y = x + 3

y = 2x - 5

Now we can solve the system:

x + 3 =2x - 5

3 + 5 = 2x -x

8  =x

The x-value of the solution is 8, then the only option that can be correct is.

So 275 gallons of melted cheese is equivalent to 2,200 pints.

The probability that he will have to wait 5 minutes or less for the next bus is given by P ( A ) = 5/12

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

A bus picks up passengers at a bus stop every 12 minutes in the morning

And , Adrian arrives at the bus stop at a random time

where he has to wait 5 minutes or less for the next bus

Now , since buses arrive every 12 minutes, Adrian will have to wait between 0 and 5 minutes if he arrives during a 5-minute window that occurs every 12 minutes.

Therefore, the probability that Adrian will have to wait between 0 and 5 minutes is the ratio of the length of the 5-minute window to the length of the 12-minute interval:

P(waiting ≤ 5 minutes) = 5/12

Hence , the probability is P ( A ) = 5/12

To find the height of the shuttle, we can use trigonometry and the concept of similar triangles. The height of the shuttle is approximately 468.675 meters.

Let's assume that the height of the shuttle is represented by 'h' meters. From the information given, we know that the distance between the camera and the launch pad is 750 meters, and the angle of elevation from the camera to the shuttle is 32 degrees.

Using trigonometry, we can set up the following equation:

tan(32°) = h / 750

To find the value of h, we can rearrange the equation:

h = tan(32°) * 750

Using a calculator, we can find the value of tan(32°) ≈ 0.6249.

Now we can calculate the height of the shuttle:

h ≈ 0.6249 * 750

h ≈ 468.675 meters

Therefore, the height of the shuttle is approximately 468.675 meters.

Step-by-step explanation:

Substituting the values of x, y, and z into the expression, we get:

2x² - y + 2(z-1) = 2(2)² - 3 + 2(4-1)

= 2(4) - 3 + 2(3)

= 8 - 3 + 6

= 11

Therefore, if x = 2, y = 3, and z = 4, then the value of the expression 2x² - y + 2(z-1) is 11.

Answer:

11

Step-by-step explanation:

if x = 2, y = 3, and z = 4.

2x²-y + 2(z-1)

Substituting the given values of x, y, and z, we get:

2x² - y + 2(z-1) = 2(2)² - 3 + 2(4-1)

= 2(4) - 3 + 2(3)

The solution to the inequality 6x - 6 < -30 is x < -4, and it is graphically represented as a closed circle at -4 and shading to the left of -4 on the number line.

To solve the inequality 6x - 6 < -30, we can follow these steps:

Step 1: Add 6 to both sides of the inequality to isolate the variable:

6x - 6 + 6 < -30 + 6

6x < -24

Step 2: Divide both sides of the inequality by 6 to solve for x:

(6x)/6 < (-24)/6

x < -4

The solution to the inequality is x < -4. This means that any value of x less than -4 will satisfy the inequality.

To graph the solution on the number line, we represent -4 as a closed circle (since it is not included in the solution) and shade the region to the left of -4 to indicate all values less than -4.

On the number line, mark a point at -4 with a closed circle:

As given in the question,

Given condition for required polynomial is given by :

Zeros of ( 5 / 6) with multiplicity 2 means zeros repeats two times we get,

= ( 6x - 5 )²  

Zeros of (- 1/ 6) with multiplicity 1 means only once

= 6x + 1

Required polynomial is :

f(x) = a  ( 6x - 5 )²  ( 6x + 1 )  __(1)

Now, f(0) = -25

Now substitute x = 0 we get,

f(0) = a [ 6(0) - 5 ]² ×  [ 6(0) + 1 ]

⇒ -25 = a ( -5)² ×  (1)

⇒ -25 = a (25)

⇒ a = -1

Substitute value of a in (1) we get,

f(x) = - ( 6x - 5 )²  ( 6x + 1 )

Open the parenthesis we get,

f(x) = - [ ( 36x² -60x + 25)( 6x + 1) ]

⇒ f(x) = - ( 216x³ -324x² + 90x + 25 )

Therefore, required polynomial of lowest degree with zeros of multiplicity of 2 for (5/6) and multiplicity of 1 for (-1/6) and f(0) = -25 is given by : f(x) = - ( 216x³ -324x² + 90x + 25 ).

The coefficient of \(x^{7}\) is 16796160.

For this, we have to find the coefficient of \(x^{7}\) in \((3x+4)^{10}\)

General Term: This term symbolizes all of the terms in the binomial expansion of (x + y)^n.

The general term in the binomial expansion of (x + y)^n is

T(r+1) = nCr x^(n-r)y^r.

Here the r-value is one less than the number of the term of the binomial expansion. Also, nCr is the coefficient, and the sum of the exponents of the variables x and y is equal to n.

We can use the general term for this.

\(T_{r+1} = (nCr) a^{n-r} x^{r}\)

Since we have to find  \(x^{7}\),

\(T_{3+1} = (10C3)(3x)^{7} 4^{3} \\T_{3+1} = [(10C3)3^{7} 4^{3} ]x^{7}\)

This is the coefficients of \(x^{7}\)

Calculating,

10C3 = 120 (using combinations)

\(3^{7} = 2187\\4^{3} = 64\)

Therefore, multiplying the 3,

Coefficients of \(x^{7}\) = 120 * 2187 *64

When applying the some rule, we only combine two equal ratios at once. Consequently, we deal with pairs of sides and angles that have equivalent ratios.

When two ratios are equal, a percentage is formed; alternatively, two equal ratios can be said to produce a proportion. When we understand that two ratios are equal, you can write a proportion. The ratios of these two numbers are equal.

When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant. Two angles are said to be complimentary if their sum is 90 degrees. Alternatively put, two angles are said to be complimentary if they combine to make a right angle.
