please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
Answers
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

F. 8
E. 7
G. x/2-7

Answers
Blue Eyes: 1/2x-6
Let the students who have green eyes be y.
1/2x-1+1/2x-6= x-y (Because the RHS is the students with brown and blue eyes and hence x-y on the LHS)
x-7=x-y
-y=-7
y=7
Therefore 7 students have green eyes.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answers
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.

Angle 4 is congruent to angle 8. This is enough information to prove that 'u' parallel to 'v'.
What are parallel lines?For a pair of lines, the perpendicular distance is equal at every point, then the pair of lines are called parallel lines.
The given information are:
1. Angle 2 is congruent to angle 4.
Angle 2 and Angle 4 are opposite angles. They are always equal.
This information does not prove that 'u' parallel to 'v'.
2. Angle 4 is congruent to angle 8.
Angle 4 and Angle 8 are corresponding angles.
This information proves that 'u' parallel to 'v'.
Angle 6 + angle 7 = 180 degrees.
The sum of the angle 6 and angle 7 are always 180 degrees.
This information does not prove that 'u' parallel to 'v'.

Step-by-step explanation:
\(if \: z = -3 + 5i \\then \: \overline{z} = - (3 + 5i) \\ hence \: z\overline{z} = (-3 + 5i)( - 3 - 5i) \\ z\overline{z} = 9 + 15i - 15i - {(5i)}^{2} \\ z\overline{z} = 9 - (25 ){i}^{2} \\ z\overline{z} = 9 - (25)( - 1) \\ z\overline{z} = 9 + 25 \\ \underline{ \boxed{z\overline{z} = 34}}\)

The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.
Answers
- Range: The range is the difference between the maximum and minimum values in a data set.
- IQR: The IQR is the range of the middle 50% of the data values. It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1).
In the given box plot:
- The lines outside the box represent the minimum and maximum values.
- The box represents the middle 50% of the data, with the line inside the box representing the median (or second quartile, Q2).
- The distance between the lower whisker and the bottom edge of the box represents the first quartile (Q1), and the distance between the upper whisker and the top edge of the box represents the third quartile (Q3).
Based on the information provided in the box plot, we can determine the range and IQR as follows:
- The minimum value is represented by the lower whisker, which ends at 15.
- The maximum value is represented by the upper whisker, which ends at 52.
- Q1 is located at the bottom edge of the box, which is 26.
- Q3 is located at the top edge of the box, which is 49.
Now we can calculate the range and IQR:
- Range: maximum value - minimum value = 52 - 15 = 37
- IQR: Q3 - Q1 = 49 - 26 = 23
Therefore, the correct statement is:
The range is 37, and the IQR is 23.
Answer:
The range is 37, and the IQR is 23.
Step-by-step explanation:
A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.
Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.From the given information, the five-number summary of the Jumping Jacks box plot is:
Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52RangeThe range is the difference between the maximum and minimum values. Therefore, the range for the data is:
\(\sf Range = 52 - 15 = \boxed{\sf 37}\)
Interquartile range (IQR)The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:
\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)
SummaryThe range is 37, and the IQR is 23.
