8. triangle ABC ( 3,2)
9. triangle ABC (4 , 4)
Given,
A set of values called coordinates helps to display a point's precise location in the coordinate plane.
we can observe the points from the graph we get the values for B' and C'.
P(x,y) P'(x₊,y₋)
P(2,5) P'=(6,4) ⇒(2₊4,5₋1)
P(3,6) P' = (3₊x' , 6₋y') ⇒ (3₊4 , 6₋1) = (7,5)
P'(7,1) P = (x'₋4 , y'₊1) ⇒ (7₋4 , 1₊1) = (3,2)
P'(8,3) P = (x'₋4 , y'₊1) ⇒ (8₋4 , 3₊1) = (4,4)
hence we acquired the desired values of the points from the graph given.

Answer:
[tex]\frac{211}{500}[/tex]
Step-by-step explanation:
[tex].4\bar{2}[/tex] means the 2 repeats till infinity
[tex].4\bar{2}[/tex] = .4222222222.....
To convert to fraction just take the first three decimal place digits 422 and divide by 1000 to convert to fraction
[tex].4\bar{2} = \frac{422}{1000}[/tex]
Dividing numerator and denominator of this fraction by 2 gives
[tex]\frac{422/2}{1000/2} =\frac{211}{500}[/tex]
This cannot be simplified further and therefore
[tex].4\bar{2} = \frac{211}{500}[/tex]
If we had chosen first 4 decimal digits then it would be[tex].4\bar{2} = \frac{4222}{10000} = \frac{2111}{5000}[/tex]
i.e. we divide by 10,000

Saturn from Earth, it looks like it has a diameter of 20 μm.
d₁=20μm
Through a telescope, the diameter looks 9,000 μm long.

A scale factor is a number that can be used to adjust the size of any geometrical figure or object in relation to its original size. It's used to draw the enlarged or reduced shape of any given figure, as well as to calculate the missing length, area, or volume of an enlarged or reduced figure. It should be noted that the scale factor only affects the figure's size and not its shape.
A scale factor is a number or conversion factor used to adjust the size of a figure without changing its shape. It is used to enlarge or reduce the size of an object. If the dimensions of the original figure and the dimensions of the dilated (increased or lowered) figure are known, the scale factor can be determined. A rectangle, for example, has a length of 5 units and a width of 2 units. If we raise the size of this rectangle by a factor of two, the sides will become 10 and 4, respectively. As a result, we can use the scale factor to determine the dimensions of the altered figures.

Which equation represents the line with slope −2/3 that passes through (3, 0)?
The following equation [tex]y=\frac{-2x}{3}+2[/tex] represents the given line.
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=3x+1. Where:
a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex].
b= the constant term that represents the y-intercept.
For solving linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.
For the given example: a=3 and b=1
The question gives:
the value of the slope (a) = -2/3the coordinates of a point = (3,0)Thus, you can write from the question information :
y=ax+b
0= -2/3*(3)+b
0= -2 + b
b=2
Now, you know the value of the slope and the constant term.
Therefore, the standard form for the linear equation is:

a company makes widgets from three machines. machine m1 makes 3000/hour, and 80% are good. machine m2 makes 4000/hour, and 90% are good. machine m3 makes 3000/hour, and 60% are good. all widgets are mixed together. what is the probability that a widget drawn at random is good
If all the widgets from the three machines are mixed together, then the probability that a good widget will be drawn at random is 0.78 or 78%.
Probability is defined as how likely an event is to occur, or how likely it is that a proposition is true.
If machine 1 makes 3000/hour and 80% are good, then the chances of it being good is 80% also or, 2400 out of 3000.
80% of 3000 is 2400
If machine 2 makes 4000/hour and 90% are good, then the chances of it being good is 90% also or, 3600 out of 4000.
90% of 4000 is 3600
If machine 3 makes 3000/hour and 60% are good, then the chances of it being good is 60% also or, 1800 out of 3000.
60% of 3000 is 1800
Mixing together the widgets from the three machines, use the formula to calculate the probability of an event which is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Probability(good) = (2400 + 3600 + 1800)/(3000 + 4000 + 3000)
Probability(good) = 7800/10000
Probability(good) = 0.78 or 78%
Hence, the probability that a good widget drawn at random is 0.78 or 78%.

The amount the restaurant needs to earn on Sunday to average $1000 per day over the three-day period is $819.
What is average ?
The average is the ratio of the sum of the number of a given set of values to the total number of values present in the set.
It is given that restaurant earns $1073 on Friday and $1108 on Saturday.
The amount which restaurant needs to earn on Sunday to average $1000 per day over the three-day period can be calculated by finding the average.
The average is given by ratio of sum of amount on each day from Friday to Sunday and divide it by number of days.
Let's assume amount earn on Sunday is $x.
So ,
[tex]\frac{1073 + 1108 + x}{3}[/tex] = 1000
1073 + 1108 + x = (1000 × 3)
2181 + x = 3000
Let's solve this equation to get the value of x.
x = 3000 - 2181
x = $819
So , amount earn by restaurant is $819.
Therefore , the amount the restaurant needs to earn on Sunday to average $1000 per day over the three-day period is $819.
