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:

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

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

Answer:

Step-by-step explanation:

using the sine ratio in the right triangle.

sin23° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{7}[/tex] ( multiply both sides by 7 )

7 × sin23° = x , then

x ≈ 2.7 ( to the nearest tenth )

----------------------------------------------------

using the tangent ratio in the right triangle

tan x = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{27}{17}[/tex] , then

x = [tex]tan^{-1}[/tex] ( [tex]\frac{27}{17}[/tex] ) ≈ 57.8° ( to the nearest tenth )

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.

Answer:

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

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: 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.

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.

Answer:

x = -1, y = 1

Step-by-step explanation:

Multiply the top equation by 2:

[tex]2x - 2y = - 4[/tex]

Leaving the bottom equation unchanged, add the two resulting equations to eliminate y, obtaining:

[tex]9x = - 9[/tex]

Solve this for x, and then substitute this value of x into the bottom equation. Finally, solve for y.

[tex]x = - 1[/tex]

[tex]7( - 1) + 2y = - 5[/tex]

[tex] - 7 + 2y = - 5[/tex]

[tex]2y = 2[/tex]

[tex]y = 1[/tex]

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

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°

Based on the outcomes, the estimated probability of the spinner landing on blue which has equal sections colored blue, yellow, and red is 0.22 or 22%.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

This table shows outcomes of a spinner with 3 equal sections colored blue, yellow, and red.

The total number of outcome is 100. The total number of favorable outcome to land blue is 22.

Thus, the estimated probability of the spinner landing on blue has to be found out is,

[tex]P=\dfrac{22}{100}\\P=0.22\\P=22\%[/tex]

Hence, based on the outcomes, the estimated probability of the spinner landing on blue which has equal sections colored blue, yellow, and red is 0.22 or 22%.
