Write an equation of the line in slope-intercept form.
Answer:
y = 2x+3
Step-by-step explanation:
You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.
To find the slope, compare the coordinates of the two points marked on the line, (0,3) and (-3,-3).
slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2
Slope-intercept equation for line of slope 2 and y-intercept 3:
y = 2x+3

If 40 chairs are bought for Rs
10000 then how many
chairs must be
Sold
for
10000
gain 60%?
Answer:
25 chairs
Step-by-step explanation:
If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?
The percent gain = 60%
Number of chairs to be sold = x
Hence:
40 chairs = 10,000
60/100= 40 - x/x × 100
0.6= 40 - x/x
Cross Multiply
0.6x = 40 - x
0.6x + x = 40
1.6x = 40
x = 40/1.6
x = 25 chairs

Find the length of side x in simplest radical form with a rational denominator.
Answer:
X = 4
Step-by-step explanation:

Which situation can be represented by 4x + 20 = 9x ?
The price of 9 books is $20 more than the price of 4 books. What is the price of a book?
The price of 4 books is $20 more than the price of 9 books. What is the price of a book?
The price of 9 books equals $24. What is the price of a book? Joyce bought x number of $4 books and $9 books. She spent $20. How many books of each price did she buy?
Answer:
The price of 9 books is $20 more than the price of 4 books. What is the price of a book?Step-by-step explanation:
Target equation is
4x + 20 = 9xComparing this with situations below
The price of 9 books is $20 more than the price of 4 books. What is the price of a book?
9x = 20 + 4x, correctThe price of 4 books is $20 more than the price of 9 books. What is the price of a book?
4x = 9x + 20, incorrectThe price of 9 books equals $24. What is the price of a book?
9x = 24, incorrectJoyce bought x number of $4 books and $9 books. She spent $20. How many books of each price did she buy?
4x + 9x = 20, incorrectA professor grades a set of exams and then computes the quartiles:
Q0 = 60. Q1 = 70. Q2 = 80 Q3 = 87. Q4 = 95
If the professor curves every grade up by 10 points, then how will Q2 be affected by the curve?
I. It will increase by 10 points
ii. It will be 10 points higher than the median for the noncurved data
III It will be halfway between Q1 and Q3 for the curved data
a. I only
b. II and III
c. I, II and III
d. I and II
e. I and III
Answer:
Answer is c. I, II and II
Step-by-step explanation:
Solution:
Answer is c. I, II and II
It will be increase by 10 points and it will be 10 points higher than the median for the noncurved data. and it will be halfway between Q1 and Q3 for the curved data.
Median for noncurved data = Q2 = 80
Median for curved data = 90
It will increase by 10 points = 90
It will be 10 points higher than the noncurved data = 90-80 = 10 points
if the set contains 20 values then, noncurved data will be:
60 _ _ _ _ 70 _ _ _ _ 80 _ _ _ _ 87 _ _ _ _ 95
Curved data will be: (all grades increased by 10 points)
70 _ _ _ _ 80 _ _ _ _ 90 _ _ _ _ 97 _ _ _ _ 105
Here, we can see median = Q2 = 90, exactly, halfway between Q1 =80 and Q3 = 97
Hence, C is the right answer
What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.
A) 7.2
B) 6.0
C) 2.8
D) 6.3
Answer:
We conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.
Step-by-step explanation:
Given
L(3,4)M(1,-2)Determining the length of LM
(x₁, y₁) = (3, 4) (x₂, y₂) = (1, -2)The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)
[tex]=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}[/tex]
[tex]=\sqrt{2^2+6^2}[/tex]
[tex]=\sqrt{4+36}[/tex]
[tex]=\sqrt{40}[/tex]
[tex]=\sqrt{4\times 10}[/tex]
[tex]=\sqrt{2^2\times \:10}[/tex]
[tex]=2\sqrt{10}[/tex]
[tex]=6.3[/tex]
Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.

Answer: No, it is not commutative. If used a square as an example, centered at (1,1). If a dilation is performed on the square of a scale factor of 3, and the square is translated 5 units downward, then the result would be different than if I switched the order, doing the translation downward first and then performing the dilation centered at (1,1).

From the attachment, we have:
[tex]BC = x + 4[/tex]
[tex]BD = 2x - 7[/tex]
[tex]GE = 51[/tex]

Because both triangles are similar, we use the following equivalent ratios:
[tex]BC : BD = GE : GF[/tex]
Substitute values for each parameter
[tex]x + 4 : 2x- 7 = 51 : 57[/tex]
Convert to fractions
[tex]\frac{x + 4}{2x- 7} = \frac{51 }{ 57}[/tex]

The diagram show a 5cm x 6cm x 7cm cuboid pls help you
Answer:
d ≈ 10.5
Step-by-step explanation:
The formula for the diagonal of a retangular prism (cuboid) is
[tex]d=\sqrt{l^2+w^2+h^2}[/tex]
1.) Plug in all the values for l, w, and h
[tex]d=\sqrt{5^2+6^2+7^2}[/tex]
2.) simplify by squaring the terms inside the square root
5 * 5 = 25
6 * 6 = 36
7 * 7 = 49
[tex]d=\sqrt{25+36+49}[/tex]
3.) Add the terms

Describe the possible lengths of the third side of the triangle given that the lengths of the other two sides are 12 feet and 18 feet.
I attached the picture too.
Answer:
6 ft < L₃ < 30 ft
Step-by-step explanation:
To obtain the answer to the question given above, we must bear in mind that:
The sum of the length of two sides of any triangle is always greater than the 3rd length i.e
L₁ + L₂ > L₃
With the above information in mind, we can obtain the answer to the question given above as follow:
Length 1 (L₁) = 12 feet
Length 2 (L₂) = 18 feet
Length 3 (L₃) =..?
Case 1:
L₁ + L₂ > L₃
12 + 18 > L₃
30 > L₃
L₃ < 30 feet
Case 2:
L₁ + L₃ > L₂
12 + L₃ > 18
Collect like terms
L₃ > 18 – 12
L₃ > 6 feet
Thus,
6 feet < L₃
Combining case 1 and 2,we obtained:
6 ft < L₃ < 30 ft
Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft

Step-by-step explanation:
The statements that are correct are:
B) The model predicts that studying for 1.5 hours will result in an exam score of 60.
C) The model predicts that studying for 2.5 hours will result in an exam score of 70.
A scatter plot is a collection of points plotted on two axes, horizontal and vertical. Scatter plots are useful in statistics because they illustrate the extent, if any, of correlation between the values of observed quantities or phenomena (called variables).
The scatter plot shows a positive relationship between study time and exam scores, with exam scores generally increasing as study time increases. However, the relationship is not linear and the increase in exam score is not always 10 points for each additional hour of study.
A) is not correct because the relationship between study time and exam score is not linear, and the increase in exam score is not always 10 points for each additional hour of study.
D) is not correct because the wording is unclear, it should be "The model predicts that studying for 4 hours will result in an exam score of (a specific number)".
