Find pairs of points with a slope of ²/₅
Answer:
Look below
Step-by-step explanation:
To find a slope with 2/5, you can use y2 - y1/x2 - x1. The 1 and 2's can be different but you cannot mistake the x and y.
1st example:
(1, 5), (6, 7)
Reason: (7-5)/(6-1) = 2/5
2nd example:
(2, 8), (7, 10)
Reason: (10 - 8)/(7 -2) = 2/5
3rd example:
(5, 2), (10, 4)
Reason: (4-2)/(10 -5) = 2/5

How is online school going so far?
I need help please.
Answer:
10. y=the total amount of money
A) y=4m
B) y= 4(5.25)
y= $21
11. y= total amount of money
A) y= 40m + 35
B) y= 40(10) + 35
y= $435
Number 10:
You know five people, you and four friends, are contributing the same amount of money for food. Lets say F = Food and M=Money. Since they are contributing the same amount of money, it would be 5 * m, or 5m. So, F would equal 5m. F=5m.
Part B- You would do the same expression, F=5m, but you would instead plug 5.25 in for m. So, 5.25 times 5 would equal 26.25 dollars.
Number 11:
Part A- Let M equal months. $40 times the number of months + 35 is the total cost, so 40m +35 is the expression.
Part B- Since the total cost is 40 dollars times the number of months + $35, you would multiply 40 * 10, to get 400 dollars over 10 months. Then you would add the $35 fee, so the answer would be $435.

[tex]\angle q, \angle s[/tex] and [tex]\angle r, \angle t[/tex].
Kindly refer to the attached image for details of the given angles and lines.
Proof that [tex]\angle q\cong \angle s[/tex] :
[tex]\begin{center}\begin{tabular}{ c c}Statements & Reasons \\ m\angle q+m\angle r=180^\circ & \angle q\ and\ \angle r\ are\ supplementary \\ m\angle r+m\angle s=180^\circ & \angle r\ and\ \angle s\ are\ supplementary \\ \angle q+\angle r=\angle q+\angle r & Algebraic substitution \\ m\angle q = m\angle s & Subtraction property of equality\end{tabular}\end{center}[/tex]
Here, subtraction property of equality is used in the last step shown in the above.
As per the Subtraction property of equality, when some value is subtracted from both the sides of the equality, equality remains the same.

The HHS band sold 250 dinners at a barbeque a child's plate cost $3.50 and a adult plate cost $7.00 a total of $1347.50 was collected how many adult plates are served
Answer:
There were 135 adults that were served.
Step-by-step explanation:
Let's use c for child's cost and a for adult's cost.
The total amount is 1347.50. With this, we can create an equation to solve for adults.
a + c = 250
3.50c + 7a = 1347.50
Using system of equations, we can plug in values to get our answer.
c = 250 - a
3.50(250 - a) + 7a =
875 - 3.5a + 7a =
3.5a = 472.5
135 = a
115 = c (when you plug a into the equations)
There were 135 adults that were served.
Answer:
135
Step-by-step explanation:
x = number of child's plate
y= number of adult's plate
x+y=250 => 1
3.50x+7y=1347.50 => 2
Multiplying equation 1 by 3.50,
3.50x+3.50y=875 =>
Subtracting equation 3 from equation 2,
3.50x +7y - 3.50x - 3.50y = 1347.50 - 875
3.50y = 472.50
y= 135
A 2×2 square is divided into four 1×1 squares. Each of the small squares is to be painted either green or red. In how many different ways can the painting be accomplished so that no green square shares its top or right side with any red square? There may be as few as zero or as many as four small green squares.
Answer:
2
Step-by-step explanation:
Let's denote all the four square by 1, 2, 3, and 4 as shown in the figure.
Each of the small squares is to be painted either green or red
The total numbers of the possible cases are:
(1) The number of cases if there is no green color square = 1 (all red)
(2) The number of cases, if there is 1 green color square = 4 as either of 4 small squares can be green (1G,2G,3G,4G).
(3) The number of cases if there is 2 green color square = 2+4=6 as
for diagonal positions: 2 which are (1G,3G), (2G,4G).for non-diagonal positions:4 which are (1G,2G), (1G,4G), (2G,3G), (3G,4G)(4) The number of cases, if there is 3 green color square = The number of cases, if there is 1 red color square= 4 as either of 4 small squares can be red (1R,2R,3R,4R).
(5) The number of cases if there is 4 green color square = 1 (all green)
So, the total numbers of possible cases = 1+4+6+4+1=16.
Now, possible positions for which no green square shares its top or right side with any red square are the diagonal positions as mentioned in point (3), i.e (1G,3G), (2G,4G)
So, the total numbers of favorable cases = 2
Hence the total number of different ways for painting each of the small squares so that no green square shares its top or right side with any red square is 2.

If the leading coefficient is negative, always factor out the negative.
-x^2+5x-6
Answer:
-1(x-2)(x-3)
Step-by-step explanation:
first we factor the negative:
-1 (x^2 - 5x +6 )
the next step, (if possible) is to guess 2 numbers that multiplied are 6
and added are -5
in this case is easy to see that those numbers are -2 and -3
The solution then is:
-1(x-2)(x-3)
If guessing the 2 numbers doesn't work, you need to complete the square

Henry predicted whether he got answers right or wrong in his 50 question exam. He identified the 31 questions he thought he got right. It turns out that Henry got 6 questions wrong that he thought he got correct and he only got 12 of the questions wrong he had predicted. What is the percentage accuracy he had with predicting his scores?
Answer:
74%
Step-by-step explanation:
Given that :
Total number of questions = 50
Total correct prediction :
Correct and right prediction = ( 31 - 6) = 25
Correct wrong prediction = 12
Total correct predictions = (25 + 12) = 37
Percentage prediction accuracy :
(Total correct prediction / total questions) * 100%
(37/ 50) * 100%
0.74 * 100%
= 74%

Answer:
see attached
Step-by-step explanation:
Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change) and "rise" (vertical change) between the marked points.
In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.
The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.
If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)
What is the slope of a line that is parallel to the line joining (7,-5) and (-5,7)
Answer:
Step-by-step explanation:
If two lines are parallel then they will have the same slope. So all you need to do is find the slope of the line that joins the two given points. You can use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. You can also graph the two points and use rise over run. [tex]\frac{7-(-5)}{-5-7} =\frac{12}{-12}=-1[/tex]
-1 is the slope of a line that is parallel to the line joining (7,-5) and (-5,7)
What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given, a line that is parallel to the line joining (7,-5) and (-5,7)
Since lines are parallel to each other thus their slope will be the same.
From the general formula of slope:
Slope = (y₂ - y₁)/(x₂ - x₁)
Slope = (7 + 5)/ -5 - 7)
Slope = -1
Therefore, the slope of a line that is parallel to the line joining (7,-5) and (-5,7) is -1.

An art gallery owner purchases art at flea markets and sells the art for a 14% profit in the gallery. If the owner purchases a piece of art for $885 at a flea market, what will be its selling price in the gallery?
Answer:
$1008.9
Step-by-step explanation:
Given
Cost of piece of art = $885
Percent profit made = 14%
Profit amount = 14% of $885
Profit amount = 14/100×885
Profit amount = 12390/100
Profit amounts to $123.90
Selling price = cost price + profit amount
Selling price = $885+$123.90
Selling price = $1008.9
Hence the selling price for the art at the gallery is $1008.9

Sara pays $4.50 for 3 pounds of bananas and 2 pounds of oranges. One pound of oranges costs $0.75 more than one pound of bananas. Let b represent the price per pound of bananas. What equation represents the situation, and what is the price per pound of each fruit?
The price of one pound of banana = b
As one pound of oranges costs $0.75 more than one pound of bananas, so, the price of one pound of orange = b+0.75.
The price of 3 pounds of banana = 3b,
and the price of 2 pounds of oranges = 2(b+0.75).
Now, as she pays $4.50 for 3 pounds of bananas and 2 pounds of oranges.
So, for this situation the required equation is
3b + 2(b+0.75) =4.5
On solving this equation, we have
[tex]\Rightarrow 3b+2b+2\times0.75=4.5[/tex]
[tex]\Rightarrow 5b +1.5=4.5[/tex]
[tex]\Rightarrow 5b =4.5-1.5=3[/tex]
[tex]\Rightarrow b =\frac 3 5=0.6[/tex]
Hence, the price of one pound of banana = $ 0.60
and the price of one pound of orange
=b+0.75= 0.60+0.75=$1.35.
