The solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

Given the equation in question;

|3x-7| - 7 = x

First, add 7 to both sides.

|3x-7| - 7 + 7 = x + 7

|3x-7|  = x + 7

Next, remove the absolute value term, this creates a ± on the right side of the question.

|3x-7|  = x + 7

3x-7  = ±( x + 7 )

The complete solution is the result of both the negative and positive portions of the solution.

For the first solution, use the positive of ±.

3x-7  = ( x + 7 )

3x - 7  =  x + 7  

3x - x = 7 + 7

2x = 14

x - 14/2

x = 7

For the second solution, use the negative of ±.

3x-7  = -( x + 7 )

3x-7  = -x - 7

3x + x = -7 + 7

4x = 0

x = 0/4

x = 0

Therefore, the solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

Zeros of a Polynomial Function

An important consequence of the Factor Theorem is that finding the zeros of a

polynomial is really the same thing as factoring it into linear factors. In this section we

will study more methods that help us find the real zeros of a polynomial, and thereby

factor the polynomial.

of a polynomial function with integer coefficients.

If the polynomial ( ) 1

As the x-values approach negative infinity, the function's values approach positive infinity, which is the right assertion regarding the graph's final behavior. The right answer is D.

A function in mathematics is an expression, rule, or law that determines the relationship between two variables, one of which is independent, and the other of which is dependent (the dependent variable). Functions can be found everywhere in mathematics, and they are essential for building physical connections in the sciences.

According to given information;

In light of the available data, the graph in the question depicts a function. The graph reveals the conclusions listed below:

At x=0, the function's value is 0.

The value of the function is 0 at x=0.

The function has a minimum value at x=2.4.

As the value of x reaches negative infinity, the function tends to positive infinity because it is open upwards.

As the value of x reaches positive infinity, the function tends to positive infinity because it is open upwards.

From the above conclusions, it can be said that "as the x-values go to negative infinity, the function's values go to positive infinity".

Therefore, option D is correct.

The value of x is 12.

Given on a line lie three points e, f and g.

therefore, ef = x ₋ 4

fg = 2x ₋ 9 and

eg = 13

we can say that ef and fg must add upto eg.

⇒ ef ₊ fg = eg

⇒ x ₋ 4 ₊ 2x ₋ 19 = 13

⇒ 3x ₋ 23 = 13

⇒ 3x = 13 ₊ 23

3x = 36

x = 36/3

x = 12

hence we get the value of x as 12.

now substitute x value to get ef and fg values.

ef = x ₋ 4  = 12 ₋ 4 = 8

fg = 2x ₋ 19 = 2(12) ₋ 19 = 24 ₋ 19 = 5

Hence we get the value of x as 12.

Step-by-step explanation:

Total 330 four-digit numbers can be formed if the number is odd and greater than 6000.

Let's tackle the problem in three steps.

First, take into account the numbers with "6" as the first digit on the left.

Then take the first eight digits of the numbers as the leftmost digit.

Last but not least, we'll use the numbers that begin with "7" as the leftmost digit.

1. As the leftmost digit, think of the numbers that begin with "6."

Any one of the final four odd digits—1, 3, 5, or 7—is acceptable (and recommended).

You are given four options.

You can use any of the remaining 8-1-1 = 6 digits for the second and third digit.

In all, it gives you 4×6×5  = 120 choices/numbers.

2.  Consider  the leftmost digit as the number starting with "6."

You have 120 more options/numbers using the same logic and analysis.

Everything is going well thus far, and you only need 120 + 120 = 240 numbers.

3.  Consider the numbers starting with "7" as leftmost digit.

Any of the final three odd digits—1, 3, and 5—may (and ought to) be used.

You have three options.

Any of the remaining 8-1-1 = 6 digits can be used for the second and third digit.

In all, it gives you 3×6×5  = 90 choices/numbers.

4. You have 120 + 120 + 90 = 330 numbers/options when everything is added up.

Hence we get 330 choices to create four digit numbers.

Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.

Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.

Given:

For 1 1/2 or 3/2 hours tony charges = $37.50

For 1 hour tony charges = 37.50 * 2/3

The general form of the standard deviation is,

[tex]SD=\sqrt{\frac{\sum (x_i-\bar{x})}{n} }[/tex]

where

xi is each value in the data set,

x-bar is the mean, and

n is the number of values in the data set.

Given,

Mean = 21.

Standard deviation = 5

Wayne's standardized score on the act = −0.6 .

Here we need to find the Wayne's Actual ACT score.

Let x be the Wayne's Actual ACT score.

So,

If a chip is randomly drawn from the bag, the probability it will be a red or a blue one is P(red or blue) = 10/19.

Probability of an event A is the number of event A divided by all possible outcomes. Mathematically,

P(A) = n(A)/n(S)

where:

n(A) = number of event A

n(S) = number of all possible outcomes or sample space.

Suppose A and B are independent outcomes, then:

P(A or B) = P(A) + P(B)

In the given problem:

Number of chips:

Blue = 3

Red = 7

Yellow = 4

Green = 5

Total chips = 3 + 7 + 4 + 5 = 19

If a chip is randomly drawn, the probability it will be a red one is:

P(red) = 7/19

Similarly,

P(blue) = 3/19
