Hello! So...

We are given the following to solve:

Solve for x.

[tex]6(x+3)-8=4x+2(4+x)[/tex]

_______________________________________________________

1. Expand both sides of the equation.

[tex]6(x+3)-8=6x+10[/tex]

[tex]4x+2(4+x)=6x+8[/tex]

[tex]6x+10=6x+8[/tex]

______________________________

2. Subtract 10 from both sides.

[tex]6x+10-10=6x+8-10[/tex]

_______________________________

3. Simplify.

[tex]6x=6x - 2[/tex]

_______________________________

4. Subtract 6x from both sides.

[tex]6x-6x=6x-2-6x[/tex]

_______________________________

5. Simplify.

[tex]0=-2[/tex]

^Notice, the sides are not equal in the solution. This being said, there would be no solution.

The equation of the circle in standard form whose center is at (h, k) = (4, 0) is (x - 4)² + y² = 26.

In this question we find the coordinates of the endpoints of the diameter of the circle, then, the center of the circle is the midpoint of the line segment. The center of the circle is found by midpoint formula:

(h, k) = 0.5 · (5, 5) + 0.5 · (3, - 5)

(h, k) = (4, 0)

And the radius of the circle is determined by Pythagorean theorem:

r = √[(4 - 5)² + (0 - 5)²]

r = √[(- 1)² + (- 5)²]

r = √26

Then, the equation of the circle in standard form is describe below:

(x - h)² + (y - k)² = r²

If we know that (h, k) = (4, 0) and r = √26, then the equation of the circle is:

(x - 4)² + y² = 26

First of all, we have to find the mean of x values.

According to the given graph, the x values are: 0, 1, 2, 2, 3, 3, 4, 5, 6, 7.

So, the mean is

The mean of x values is 3.3.

The y values are: 2, 2, 3, 4, 4, 4, 5, 6, 8, 9.

The mean would be

The mean of y values is 4.4.

Now, we find the standard deviation for x values and y values.

The real and complex zeros for the function given as .f(x) = x³ - x² + 3x - 3 are x = 1 and x = ±i√3, respectively

The equation of the function is given as

f(x) = x³ - x² + 3x - 3

Group the terms of the function in two's

So, we have the equation

f(x) = (x³ - x²) + (3x - 3)

Factor each group in the function

f(x) = x²(x - 1) + 3(x - 1)

Factor out x - 1

f(x) = (x² + 3)(x - 1)

Set to 0

(x² + 3)(x - 1) = 0

This gives

x² = - 3 and x = 1

Evaluate the roots

x = ±i√3 and x = 1

Hence, the zeros of the equation are x = ±i√3 and x = 1

The sum of the first 7 terms for the geometric sequence with first term 3, seventh term 46,875, and common ratio 5 is 58,583.

A geometric progression is a sequence where each and every succeeding term is formed by multiplying the preceding term by a constant number. That constant number is called common ratio.

The common ratio is provided to be 5. While the first term is 3.

The seventh term is 46875.

The formula for sum of n terms of a GP is,

Sn = a(rⁿ-1)/(r-1)

We have to find sum of seven terms,

Sn = a(r⁶.r - 1)/(r-1)

Putting,

a = 3

r = 5

n =6

Sn = 3(5⁶.5 - 1)/(5-1)

Sn = (3.5⁶.5 - 3)/4

Sn = (46875×5 - 3)/4

Sn = (234375-3)/4

Sn = 234372/4

Sn = 58593.

In order to determine which person is the first to win both prizes, you have to find the least common multiple to both numbers 14 and 10.

To determine what is the least common multiple number you proceed as follow:

You list different multiples of each number 14 and 10.

For 14: 14 28 42 56 70 84 98 112

For 10: 10 20 30 40 50 60 70 80

The least common multiple is 70, becasue is the first common number in each list.

Hence the 70th person in the line will win both prizes.

If a ball is thrown directly upward with a velocity of 88 ft/s, its height (in feet) after t seconds is given by y = 88t - 16t².The ball will reach its maximum height at 121 feet.

Given equation:

y = 88t - 16t²

Maximum height dy/dt = 0

88-32t = 0

32t = 88

t = 88/32sec

t = 2.75sec

Hence,

Maximum height attained by the ball :

Maximum height attained by the ball = 88(2.75)-16(2.75)²

Maximum height attained by the ball = 242 - 121

Maximum height attained by the ball = 121 feet

Therefore the maximum height is 121 feet.

The mean increases by 23 and the median stays the same.

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the middle value.

Given the data set: 352, 409, 424, 471, 497, 503, 515, 525, 561

(a) Mean = [tex]\frac{352+409+424+471+497+503+515+525+561}{9}[/tex]

Mean = [tex]\frac{4257}{9}[/tex]

= 473

The number 561 from this list changes to 768.

New mean = [tex]\frac{352+409+424+471+497+503+515+525+768}{9}[/tex]

= [tex]\frac{4464}{9}[/tex]

= 496

Thus, the mean increases by 496 - 473 = 23.

(b) Median = mid value

= 497

When the number 561 changes to 768, still the mid value will remain the same i.e. the median remains the same.

Therefore, the mean increases by 23 and the median stays the same.

nothing has been done yet, the statement is given as stated above the statement

The score required for the exam so that the score is higher than 30.85% is 412 for certain standardized test.

The formula for finding the z-score is;

z = (x - μ)/σ

x = sample size

μ = mean of the population

σ = standard deviation of the population.

The given values are-

μ = 421

σ = 18

Probability = 30.85% = 0.3085

Check the z-score from the negative z table for 0.3085

z score = -0.5

Put the values in z formula and find x.

z = (x - μ)/σ

-0.5 = (x - 421)/18

Simplifying;

x = -9 + 421

x = 412

Thus, the score required for the standardized test is found as 412.

Answer:

B

Step-by-step explanation:

it is simple.

because AB > AD, their size representations must have the same relationship.

therefore,

9x - 16 > 1.5x + 42

that could be simplified to

7.5x > 58

The inequality that represents AB > AD is B: 9x - 16 > 1.5x + 42.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, In Rectangle ABCD the length of AB is greater than the length of AD.

∴ The inequality that represents this is AB > AD which is,

As you can see in the given figure the minute hand of a clock rotate from 12:40 to 1:10 formig a straigth angle.

A straight angle in radians is π radians.

It is known that any exponential function with the form f(x)=a^x is an increasing function while a function of the form g(x)=a^(-x) is a decreasing function.

Furthermore, it a function h(x) is increasing, then the function -h(x) is decreasing. By analogy, if a function k(x) is decreasing, then -k(x) is increasing.

Now let's analyze the functions from the problem.

Since (6/7)^x is increasing and the multiplying factor of 10 is positive, then the function f(x) is also increasing.

Use these rules to find whether each function is increasing or decreasing.

Remember that increasing functions are used to represent growth while decreasing functions are used to represent decay.
