If m = (3x-1) and n = (3x+1),sjow that x² = mn+1 by 9
Step-by-step explanation:
[tex] {x}^{2} = \frac{mn + 1}{9} [/tex]
[tex](3x - 1)(3x + 1)[/tex]
[tex]9 {x}^{2} - 1[/tex]
[tex] {x}^{2} = \frac{9 {x}^{2 } - 1 + 1 } {9} [/tex]
[tex] {x}^{2} = \frac{9 {x}^{2} }{9} [/tex]
[tex] {x}^{2} = {x}^{2} [/tex]
So this identity is true.

Answer:
the change in x is 1, the change in y is 4, the slope is 1/4
Step-by-step explanation:
the time increases by one minutes as the temperature increases by 4 degrees. therefore, every one minutes the temperature increases by four degrees. 1/4
Answer:
1, 4 and 4
Step-by-step explanation:
x = 10-9 = 1
y = 64-60 = 4
Rate of change = temperture / time
= 4/1
= 4.

Answer:
10, 11, 12, 13
Step-by-step explanation:
2 + 8 = 10
3 + 8 = 11
4 + 8 = 12
5 + 8 = 13
x | y
2 | 10
3 | 11
4 | 12
5 | 13
y = x + 8, so take x, add 8 to it, and you get y
The amount of money that Maria had in a savings amount at the beginning of 2018 was $2,750. At the beginning of 2019, the same saving account
Complete question :
The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750. At the beginning of 2019, the same savings account now had $3,201 in it.
By what percent did Maria’s savings increase from 2018 to 2019? Show the work that leads to your answer and do not round.
Answer:
16.4%
Step-by-step explanation:
Given that:
Amount in 2018 = 2750
Amount in 2019 = 3201
Percentage increase in savings :
[(amount saved in 2019 - Amount saved in 2018) / Amount saved in 2018] * 100%
[(3201 - 2750) / 2750] * 100%
= 451 / 2750 * 100%
= 0.164 * 100%
= 16.4%
Find the measure of an angle
in a regular polygon with 28
sides.
[?] degrees
Round to the nearest whole number.
Answer:
167º
Step-by-step explanation:
The interior angles in an n-gon add up to 180(n-2). So, the interior angles in a 28-gon add up to 180(28-2)=180(26)=4680. To find out the measure of one angle divide 4680 by 29. 4680/28 is about 167.

what is the surface area of this rectangle prison of 6 9 4
Answer:
You need to be specific on which is the length, height and width. Making the most basic assumption I would have to assume the answer is 228
Step-by-step explanation:
Formula for the surface area of a rectangular prism is A=2(wl+hl+hw)
A = 2 x (9 x 6 + 4 x 6 + 4 x 9)
A = 2 x (54 + 24 + 36)
A = 2 (114)
A = 228
A bookcase is to have 5 shelves including the top. The height of the bookcase is to be 3 feet more than the width and only 20 feet of lumber is available. Use an equation to determine the width and height of the bookcase?
Answer:
The width and height is 1.375 and 4.375 respectively
Step-by-step explanation:
The computation of the width and height of the book case is shown below:
Let the width be w
And, the height be h
So, the following equations should be made
5w+3h=20 ......(i)
h = w + 3......(2)
Now
put the value of h in equation (1)
5w + 3(w + 3) = 20
5w + 3w + 9 = 20
8w = 20-9
8w = 11
w = 11 ÷ 8
= 1.375
And, the height would be
= 1.375 + 3
= 4.375

if pqrs is a square solve for x what do I do?
Answer:
x = 11
Step-by-step explanation:
Properties of a square,
1). Diagonal of a square bisect the opposite angles.
2). All interior angles of a square measure 90°.
From these properties,
m∠PQR = 90°
Since, diagonal QS bisects angle PQR,
m∠PQS = m∠RQS = 45°
(6x - 21)° = 45°
6x = 45 + 21
6x = 66
x = 11

An advertising company is curious about the impact the lengths of their television advertisements have on viewers' feelings about a product. They showed advertisements of different lengths to a group of volunteers and asked the volunteers to rate how positive they felt about the product on a scale of 111 to 101010. Their data is shown in the table below.
Avg. product rating/ 6.0/ 7.0/ 5.0/ 3.0/ 2.5
Ad length (seconds) 30/ 45/ 60/ 75/ 90
Answer:
Graph C
Step-by-step explanation:
Khan Academy
The correct graph that represents the given data effectively would be:
Graph C
The given data offers the average ratings of the product and the length of their advertisements in seconds.The third graph most effectively shows the data as it contains provided variables on the appropriate axis i.e. ad length on the x-axis and the average rating on the y-axis. The other graphs fail to represent the explanatory variable and the other variable effectively.Thus, 'graph C' in the scatter plot format is the correct answer.

3x^2-4x-7
3x^2+3x-7x -7
Common factor from two pairs
3x^2 +3x-7x-7
3x(x+1) - 7(x+1
Rewrite in factored form
3x(x+1) - 7(x+1)
(3x-7) (x+1)

Answer: 50+10w=200 w=15
Step-by-step explanation:
So we know that Kareem starts off with $50 and every week he gains an additional $10 so as many weeks it takes to get $150 in addition to the $50 he already has to get $200. so $50+$10w=$200 where w represents the number of weeks it takes until the sum is 200
