Answer: x=5
Step-by-step explanation:
3x appears two times and so does 2x +2. That created the equation 3x + 3x + 2x + 2 + 2x + 2=54. Combine like terms. You get 10x +4=54. Then you solve. Inverse operation: You subtract 4 from 54. Which is 50, then divide by 10. X=5
The value of the x for the given rectangle is 5 units.
What is the perimeter of a rectangle?The whole distance that a rectangle's boundaries, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the sum of its four sides.
Given, The perimeter of the rectangle below is 54 units.
Also given the length of the rectangle = 3x
and the width of rectangle = 2x + 2
Since, Perimeter of rectangle = 2 *( length + width)
Perimeter of rectangle = 2 * (3x + 2x + 2)
Since we have a perimeter
54 = 2 *(5 x + 2)
5x + 2 = 27
5x = 25
x = 5
Therefore, For the given rectangle, the value of x is 5 units.

How many solutions does the following equation have ?
-42 – 7 + 10x = -7 + 6x
Pls help and explain
The equation -42 - 7 + 10x = -7 + 6x has one solution x = 10.5.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows:
-42 - 7 + 10x = -7 + 6x
Combine like terms in the equation,
-49 + 10x = -7 + 6x
Add 49 to both sides,
10x = 42 + 6x
Subtract 6x from both sides,
4x = 42
Divided both sides by 4 into the equation, and we get
x = 10.5
Thus, the equation has one solution x = 10.5.

find the slop
-4 1
-1 - 4
2 -9
5 -14
8 -19
Answer:
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .Teachers use different words for the y-coordinates and the the x-coordinates . Some call the y-coordinates the rise and the x-coordinates the run . Others prefer to use Δ notation and call the y-coordinates Δ , and the x-coordinates the Δ .These words all mean the same thing, which is that the y values are on the top of the formula (numerator) and the x values are on the bottom of the formula (denominator)!The slope of a line going through the point (1, 2) and the point (4, 3) is 13. Remember: difference in the y values goes in the numerator of formula, and the difference in the x values goes in denominator of the formula.Can either point be (1,1) ? There is only one way to know! First, we will use point (1, 2) as 1,1, and as you can see : the slope is: 13 . Now let's use point (4, 3) as 1,1, and as you can see , the slope simplifies to the same value: 13point (4, 3) as (1,1) =2−12−1=3−24−1=13 point (1, 2) as (1,1) =2−12−1=2−31−4=−1−3=13 Answer: It does not matter which point you put first. You can start with (4, 3) or with (1, 2) and, either way, you end with the exact same number! 1/3
Example 2 of the Slope of A line The slope of a line through the points (3, 4) and (5, 1) is −32 because every time that the line goes down by 3(the change in y or the rise) the line moves to the right (the run) by 2.This is because any vertical line has a Δ or "run" of zero. Whenever zero is the denominator of the fraction in this case of the fraction representing the slope of a line, the fraction is undefined. The picture below shows a vertical line (x = 1). vertical line The slope of a horizontal line is zero This is because any horizontal line has a Δ or "rise" of zero. Therefore, regardless of what the run is (provided its' not also zero!), the fraction representing slope has a zero in its numerator. Therefore, the slope must evaluate to zero. Below is a picture of a horizontal line -- you can see that it does not have any 'rise' to it.

Answer:
x = 3Step-by-step explanation:
given:
f(x) = g(x)
f(x) = x³ - 3x² + 2
g(x) = x² - 6x + 11
find: the value of x
solution:
as given f(x) = g(x) equate each side x³ - 3x² + 2 = x² - 6x + 11 combine similar terms and equate to zero: x³ - 4x² + 6x - 9 = 0 solve by factoring: (x - 3) (x² - x + 3) use the Zero factor principle: x - 3 = 0 x = 3 for x² - x + 3 = 0 ----this is a complex solution.
therefore, the value of x = 3

Jordan surveys the first five bicyclists to finish the race. Which best explains which sample is likely to be the most valid?
Answer: A) Nathan’s because his sample was more random
Step-by-step explanation: sampling methods quiz on edge
Nathan's sample is likely to be the most valid. Nathan's because his sample contained elements of the population.
What is a Survey?In order to gather information on a service, product, or process, a survey is described as an act of looking at a process or asking a predetermined sample of people. Surveys used to gather data ask a specific set of individuals about their beliefs, actions, or knowledge.
Given, To find out how much time cyclists are in a race train on average each week, Nathan and Jordan develop questionnaires. Every fifth cyclist who crosses the finish line after a race is surveyed by Nathan. Jordan takes a survey of the top five cyclists who cross the finish line.
Since Nathan's sample contained elements of the population.
and it is more random.
The sample used by Nathan is probably the most reliable. Nathan's because the population was represented in his sample.

Jenny works in a picture framing shop. She has a function f(x) equals X +2 that find the size of a square frame, given a picture of side length X in inches. She has a function p(x) equals 3X that gives the price in dollars for the frame. What is the single function that Jenny can use to give a customer a price for a picture with an edge length of X
Given:
The function for size of a square frame is
[tex]f(x)=x+2[/tex]
where, x is the side length of the picture.
The function for the price in dollars for the frame is
[tex]p(x)=3x[/tex]
To find:
The single function for the price of a picture with an edge length of x.
Solution:
We know that, for a picture with an edge length of x.
Size of a square frame = f(x)
Price in dollars for the frame = p(x)
Single function for the price of a picture with an edge length of x is
[tex](p\circ f)(x)=p(f(x))[/tex]
[tex](p\circ f)(x)=p(x+2)[/tex] [tex][\because f(x)=x+2][/tex]
[tex](p\circ f)(x)=3(x+2)[/tex] [tex][\because p(x)=3x][/tex]
Let the name of this function is c(x). So,
[tex]c(x)=3(x+2)[/tex]
Therefore, the required function is [tex]c(x)=3(x+2)[/tex].

Find the equation of the line shown.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
First we need the slope which is finding from the following equation.
slope = y(B) - y (A) / x (B) - x(A)
Suppose ;
A = ( 0 , 0 ) & B = ( 10 , 5 )
Thus :
slope = 5 - 0 / 10 - 0
slope = 5 / 10
slope = 1 / 2
__________________________
We have following equation to find the point-slope form of the linear functions.
y - y(0) = s × ( x - x(0) )
__________________________
y(0) & x(0) are the coordinates of the point which line through it like A = ( 0 , 0 ) or B = ( 10 , 5 ).
s = slope
__________________________
I choose point A to put in the equation.
So :
y - ( 0 ) = 1/2 × ( x - ( 0 ) )
y - 0 = 1/2 × x - 1/2 × 0
y = 1/2 × x
y = x/2

Step-by-step explanation:
The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 30 hours and the median is 26.2 hours. Twenty-four of the families in the sample turned on the television for 15 hours or less for the week. The 11th percentile of the data is 15 hours. Step 4 of 5 : What is the value of the 50th percentile?
Answer:
26.2 hours
Step-by-step explanation:
From the given information:
The objective is to determine the value of the 50th percentile.
The median is the 50th percentile, which categorically divides the data into two equal parts. It is a number separating the higher half of a data sample from the lower half. This implies that the median stands in place for the 50th percentile of the data.
Thus, the 50th percentile value is 26.2 hours
