On a coordinate plane, line M N goes through points (2, 3) and (negative 3, 2). Point K is at (3, negative 3).
Which point could be on the line that is perpendicular to Line M N and passes through point K?
(0, −12)
(2, 2)
(4, 8)
(5, 13)
Answer:
suitable is (4, 8)
Step-by-step explanation:
slope of MN (y2-y1)/(x2-x1) = (2-3)/(-3-2)= -1/-5 = 1/5
line MN and line K is perpendicular
(1/5)*(m2) = -1
slope of k which is m2 is -5
slope of K (y2-y1)/(x2-x1)= 5
slope of MN (-3-y1)/(3-x1)=5
suitable is (4, 8)

Answer:
D
Step-by-step explanation:
As is often the case with multiple choice questions, a simple check of the reasonableness of the answers will identify the correct one.
Here, the key is that the center of mass will be at the non-zero mass if one of them is zero. Assuming m2 = 0, the center of mass will have coordinates (x1, y1).
Checking the offered expressions when m2=0, we have ...
A. (m1x1/(2m1), m1y1/(2m1)) = (x1/2, y1/2) ≠ (x1, y1)
B. (m1(x1 +x2)/(2m1), 0) = ((x1+x2)/2, 0) ≠ (x1, y1)
C. (m1x2/m1, m1y2/m1) = (x2, y2) ≠ (x1, y1)
D. (m1x1/m1, m1y1/m1) = (x1, y1) . . . . . the answer we're looking for

i. Total cost price
ii. Total selling price
iii. Profit or loss percent correct to one decimal place.
Answer:
1.1%
Step-by-step explanation:
cost price=1.10×12
=$13.20
selling price=(12-3)×1.45
=9×1.45
=$13.05
loss= cost price-selling price
=13.20-13.05
=0.15
loss percent=0.15/13.20×100

Answer:
K = (-5, 14)
Step-by-step explanation:
For writing equations of parallel and perpendicular lines, it is convenient to start with equations in general form:
ax +by +c = 0
Rewriting the given equations, we have ...
y = 1/2x -1
x -2y -2 = 0 . . . . . line d
y = -3x +2
3x +y -2 = 0 . . . . . line d'
__
A parallel line will have the same coefficients, but a constant appropriate to the required point on the line.
Parallel to d' through A(-1, 2):
3(x -(-1)) +(y -2) = 0
3x +y +1 = 0 . . . . . . . . simplify
__
A perpendicular line will have the coefficients swapped and one of them negated. Again, the constant is appropriate to the required point.
Perpendicular to d through B(3, -2):
2(x -3) +(y -(-2)) = 0
2x +y -4 = 0 . . . . . . . . simplify
__
The solution to this system of equations can be found by subtracting the second equation from the first:
(3x +y +1) -(2x +y -4) = (0) -(0)
x +5 = 0
x = -5
Substituting into the second equation gives ...
2(-5) +y -4 = 0
y -14 = 0
y = 14
The coordinates of point K are ...
K = (-5, 14)
_____
Additional comment
The general line through the origin ...
ax +by = 0
can be translated to go through point (h, k) by the usual method for translating functions. The variable x is replaced by (x -h), and the variable y is replaced by (y -k). Using the general form equation means we can keep the variables and constants all on the same side of the equal sign, saving a bit of work and confusion.
a(x -h) +b(y -k) = 0 . . . . . . line through point (h, k)

A student's workout is graphed on the grid below. What’s the domain and range?
Answer:
Domain [0,50] and Range [0,100]
Step-by-step explanation:
The domain of a graph is the values that x takes on in the graph.
We see the x values for the graph go from 0 to 50.
Since both ends of the graph are closed circles we will use brackets:
D [0,50]
The range of a graph is the values that y takes on in the graph.
We see the y values for the graph go from 100 to 0.
R [0,100]
We can also write them in interval notation:
Domain: [tex]0\leq x\leq 50[/tex]
Range: [tex]0\leq y\leq 100[/tex]

Consider the line 3x+8y= 1.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
slope of a line parallel to this line= -3/8
slope of a line perpendicular to this line= 8/3
Step-by-step explanation:
The general equation of a line in terms of a and b is:
y=ax+b where a=slope
in order to get the slope of the line we have to write its equation as the form shown above:
3x+8y=1
8y= -3x+1
y= (-3/8)x+(1/8)
so slope= -3/8
Parallel lines have equal slopes
⇒ slope of parallel line= -3/8
The slope of the line perpendicular to another line is the opposite reciprocal of the original line's slope. This means that we have to exchange the numerater by the denomenator and multiply the obtained number by a negative sign:
⇒ slope of perpendicular line= -(-8/3) = 8/3
Solve the following system of equations using substitution.
3x + 2y = 16
3x - 1 = y
Answer:
x=2
y=5
Step-by-step explanation:
Since we have an equation that is set equal to why with x in it, we can multiply it by 2 to get 6x-2=2y.
We can then plug that in for 2 +2y in the equation above, giving us 3x+6x-2=16 or 9x-2=16.
From there we add 2 to both sides and get 9x=18.
Then divide both sides by 9 to get x=2.
Then plug x=2 in for the equation below and get 6-1, or 5.
Giving us our answers, x=2 and y=5

Answer:
y = 120°
Step-by-step explanation:
If AC ≅ AD and BC ≅ BD then the shape of the figure is a kite.
Therefore, ∠D ≅ ∠C
Sum of interior angles in a kite = 360°
⇒ ∠A + ∠B + ∠C + ∠D = 360°
⇒ 120° + ∠B + 100° + 100° = 360°
⇒ ∠B = 40°
Sum of interior angles of a triangle = 180°
⇒ ∠B + ∠BDY + ∠y = 180°
⇒ 40° + 20° + ∠y = 180°
⇒ ∠y = 120°
what is the equation of the straight line that passes through the point (2,-4) with the slope -2?
Answer:
y = - 2x
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 2 . then
y = - 2x + c ← is the partial equation
to find c substitute (2, - 4 ) into the partial equation
- 4 = - 4 + c (add 4 to both sides )
0 = c
y = - 2x + 0 , that is
y = - 2x ← equation of line

Answer:
0,24 m
Step-by-step explanation:
La table est un rectanble donc l'angle en haut à droite est de 90°.
Tu connais donc un angle et le côté opposé à l'angle et tu cherche le côté adjacent.
On sait que tan(â) = [tex]\frac{Cote oppose}{Cote adjacent}[/tex] donc :
tan(40)= [tex]\frac{1,27}{x}[/tex]
[tex]\frac{1,27}{tan(40)} = x[/tex]
donc x ≈ 1,51 m
Le trou du mileu est à [tex]\frac{2,54}{2}[/tex] soit 1,27m du bord.
Donc elle doit taper à 1,51 - 1,27 = 0,24m du trou du milieu.

At a community fund raiser event, bracelets cost $3 and necklaces cost $6. Complete the patterns in
the first two columns for the cost of 0, 1, 2, 3, and 4 pieces of jewelry. Write the ordered pair for the
corresponding terms in the third column. Then graph the ordered pairs
Answer: Attached photos, and the last question of my explanation.
Step-by-step explanation: If "bracelets cost $3 and necklaces cost $6" that means we will multiply.
1. for Bracelets (1 bracelet = $3)
(0 x 3 = 0) 1. $0
(1 x 3 = 3) 2. $3
(2 x 3= 6) 3. $6
(3 x 3 = 9) 4. $9
(3 x 4 = 12) 5. $12
Explanation: We have to multiply 5 different numbers to fill in the 5 rows of bracelets & necklaces. (0,1,2,3,4 = 5 numbers). For example, if we buy 2 bracelets, 1 bracelet = $3 and 3*2=6 so it would be 6.
2. for Necklaces (1 necklace equals $6)
(0 x 6 = 0) 1. $0
(1 x 6 = 6) 2. $6
(6 x 2 = 12) 3. $12
(6 x 3 = 18) 4. $18
(6 x 4 = 24) 5. $24
3. coordinates
1. (0,0)
2. (3,6)
3. (6,12)
4. (9,18)
5. (12,24)
Putting the coordinate pairs on the graphs: the first number is x and the second is y.
4. I displayed a photo of what the chart, and graph should look like.5. What is the relationship between the corresponding terms in the two sequences: The second sequence is the product of multiplying sequence 1 and sequence 2.
Sam filled 4 large bottles and 6 small bottles with 6.8 litres of orange juice . Each large bottle could hold 0.5 litres more than each small bottle. How much orange juice can a small bottle hold?
Answer:
0.48 litres
Step-by-step explanation:
let the large bottles be x and small bottles be y
4x + 6y = 6.8
x = 0.5 + y
so substituting x in equation 1:
4(0.5 + y) + 6y = 6.8
2 + 4y + 6y = 6.8
10y = 4.8
y = 0.48

Use the greatest common factor of 84 and 48 to write the sum 84+48 as a product. Write a whole number in each black.
Answer: Below
Step-by-step explanation:
Looking at the numbers, they already seem to be multiples of fours. If we try to scale four up, 12 is the next biggest factor.
84 = 12 * 7
48 = 12 * 4
7 + 4 = 13
12 * 13 = 84 * 48
12 * 13 = 132
