For the given points B(-1, -10) is reflected over the line y = x , the coordinates of B' is given by ( -10 , -1).
As given in the question,
Given points :
B (-1, -10)

Identify the parameter you are trying to estimate for 90%
Write the equation of a line in slope intercept form that passes through (-15, 20) and is parallel to x - 5y = 5
First step is to write the equation in slope-intercept form
[tex]x - 5y = 5\\-5y = -x+5[/tex] To make simplification easier, multiply negative to both sides
[tex]5y = x-5\\[/tex] Now, you must divide 5 to both sides to isolate the variable
[tex]y = \frac{x}{5} - 1[/tex] To tell the slope more easily, turn [tex]\frac{x}{5}[/tex] into [tex]\frac{1}{5} x[/tex]
To rewrite the equation: [tex]y = \frac{1}{5} x - 1[/tex]
Now, you are able to see the slope(m) being [tex]\frac{1}{5}[/tex]
Next, you use the formula y=mx+b to solve for b (replace your newly found slope and points "x" and "y"
[tex]20 = (\frac{1}{5} *-15) + b\\20 = -3 + b\\b -3 = 20\\b = 23[/tex]
Final Answer: [tex]y = \frac{1}{5} + 23[/tex]

Deshaun is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.
Company A charges $84 and allows unlimited mileage.
Company B has an initial fee of $75 and charges an additional $0.60 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Step-by-step explanation:
Deshaun is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices. Company A charges $84 and allows unlimited mileage. Company B has an initial fee of $75 and charges an additional $0.60 for every mile driven. For what mileages will Company A charge less than Company B? (Use m for the number of miles driven, and solve your inequality for m.)
inequality: 0.6m + 75 < 84
subtract 75 from both sides:
0.6m + 75 - 75 < 84 - 75
0.6m < 9
divide both sides by 0.6:
0.6m/0.6 < 9/0.6
m < 15
SO:
For anything less than 15 miles, Company A charges less than Company B.

Answer:
c = 23
Step-by-step explanation:
To start, the interior of ∠L is needed to complete the equation. Since the total value of an interior and exterior angle is equal to 180°, we can confirm that 180° - 83° = 97°. Now, we can plug in the numbers.
(2c + 51)° = 97°
Next, you want to subtract 51 from both sides.
(2c + 51) - 51 = 97 - 51
2c = 46
Lastly, you isolate c by dividing 46 by 2.
c = 46 ÷ 2
c = 23

Figure LMNO is dilated to form figure L'M'NO'.
Where is the center of dilation located?
on a vertex of figure LMNO
What is the scale factor of the dilation?
pls help quickly;;;
The location of the center of dilation in the figure and the image formed following the dilation is the point N
The scale factor of the dilation is 0.5
What is a dilation transformation?A dilation transformation resizes an object such that the lengths of the sides of the image (the object formed) following the dilation of the original image has sides that are a constant multiple of the side lengths of the original object.
The center of dilation is a reference and fixed point, such that the center of is in the same location relative to the preimage and the image.
The location or point shared by both the figure LMNO and the image of LMNO formed following the dilation, which is figure L'M'N'O' is the point N.
Therefore;
The center of dilation is the point NThe scale factor of the dilation is found using the definition of a scale factor, which is the ratio of the scale of a new figure to the scale of an original figure, therefore:
[tex]The \ scale \ factor,\, s.f. = \mathrm{\dfrac{Length \ of \ the \ sides \ of \ L'M'N'O'}{Length \ of \ the \ sides \ of \ LMNO}}[/tex]

Which gives:
[tex]s.f. = \dfrac{M'L'}{ML} =\dfrac{\sqrt{10} }{2 \cdot \sqrt{10} } = \dfrac{1}{2}=0.5[/tex]

PLEASE HELP ASAP (100 POINTS) If the line of best fit is y = 1.416x − 0.76, what is the residual value for the coordinate (7, 8)?
A. −1.152
B. 1.152
C. −3.568
D. 3.568
Answer:
A: -1.152Step-by-step explanation:
y = 1.416x − 0.76
For (7, 8):
residual value = Measured value - Predicted value
residual value = (actual y-coordinate of the point, y2) - (value of y from the equation, y1)
When x = 7:
value of y from the equation, y1 = 1.416*7 - 0.76
y1 = 9.912 - 0.76
y1 = 9.152actual y-coordinate of the point, y2 = 8
From:
residual value = (actual y-coordinate of the point, y2) - (value of y from the equation, y1)
residual value = y2 - y1
residual value = 8 - 9.152
residual value = -1.152Answer:

What is probability?
Probability is defined as the possibility of an event to occur.
An automated weight monitor can detect underfilled cans of beverages with probability [tex]0.98[/tex]
