The value of k for which x²-4kxy+4y²=0 represent a pair of straight is?​

Please help me!!

Answer:

y= 6x-1

Step-by-step explanation:

6x-y=1

-y= -6x+1  (move x over to the right side)

y= 6x-1 (divide both sides by -1)

Step-by-step explanation:

75-40= 35

[tex] \frac{35}{40} \times 100\% = 87.5\%[/tex]

Answer:

y = 6/5x

Step-by-step explanation:

1. [tex]y = \frac{-1-5 }{-5-0}[/tex]

2. subtract the two number on the top of the fraction bar to get 6

3. do the same for the denominator to get 5

4. your final answer is [tex]\frac{6}{5}[/tex]

Answer:

the answer is 23

Step-by-step explanation:

100/50=2

46/2=23

Answer:

23

Step-by-step explanation:

50/x=100/46

(50/x)*x=(100/46)*x       - we multiply both sides of the equation by x

50=2.17391304348*x       - we divide both sides of the equation by (2.17391304348) to get x

50/2.17391304348=x

23=x

x=23

now we have:

46% of 50=23

Answer:C

Step-by-step explanation:

Notice that the line is heading downward. This is a clue that it has a negative slope. Think of slope as rise over run. Rise being up or down on the y axis and run being left or right on the x axis. If we start at (0,0) and count down 3 squares and left 4 squares we can see that -3/4 is the slope.

Answer:

A. 3/4

Step-by-step explanation:

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

(-8, -6) (-4, -3)

[tex]\frac{-3 + 6}{-4 + 8} = \frac{3}{4}[/tex]

Answer:

20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

WOW, that's a lot of points!!

To find the answer for this problem, you take 80% of 50.

In the bag, 20% of the marbles are blue. That means that the rest of the 80% are not blue. So, take 0.8 * 50 = 40. 40 marbles that are not blue.

Answer:

x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(x−6)+12=20

(4)(x)+(4)(−6)+12=20(Distribute)

4x+−24+12=20

(4x)+(−24+12)=20(Combine Like Terms)

4x+−12=20

4x−12=20

Step 2: Add 12 to both sides.

4x−12+12=20+12

4x=32

Step 3: Divide both sides by 4.

4x

4

=

32

Answer:

  Perimeter: 17 inches

  Area: 8 square inches

Step-by-step explanation:

The ratio of perimeters is the same as the similarity ratio.

  JKLM perimeter / ABCD perimeter = P/68 = 1/4

Multiplying by 68, we get ...

  P = 68/4 = 17 . . . . inches

__

The ratio of areas is the square of the similarity ratio.

  JKLM area / ABCD area = A/128 = (1/4)^2

Multiplying by 128, we get ...

  A = 128/16 = 8 . . . . square inches

__

Perimeter = 17 inches

Area = 8 square inches

x= -36

Step-by-step explanation:

Step 1

from the attachment, Mai's solving is given as

1/3 (1/2x- 9) = 1/2 (x+18)

1/6x-3= 1/2x+9

1/4x-3=9

1/4x=12

x=48

Mai's error started when he subtracted wrongly 1/2 x from 1/6x which gave him 1/4 x instead of - 1/3 x.

Solving correctly, we have that

1/3(1/2x-9) = 1/2(x+18)

1/6x -3= 1/2x+ 9

taking like terms to like terms

1/6x-1/2x= 9+3

(1-3)/6x= 12

-2/6x= 12

-1/3x= 12

multiplying both sides by -3

-1/3x X -3 = 12 X -3

x= -36

Answer:

61 is the rate at which the population changes every year

Step-by-step explanation:

Given

[tex]2000 - 61k = 48[/tex]

Required

Interpret 61

A linear equation has the form:

[tex]y = mk + b[/tex]

or

[tex]b + mk = y[/tex]

Where m is the rate

By comparison:

[tex]mk = -61k[/tex]

[tex]m = -61[/tex]

Hence, 61 represents the rate at which the population changes yearly.

The negative sign implies that the populatiin reduces

Answer:

89 employees

3 uniforms left

Step-by-step explanation:

Number of Uniforms per employee = 5

Uniform per pack = 8

Number of packs = 56

Total number of uniforms :

56 * 8 = 448 uniforms

Number of employees who can get uniform :

1 employee = 5 uniforms

Number of employees = 448 / 5 = 89.6

Hence, 89 employees

Yes, (448 - (89*5)

= 448 - 445

= 3 uniforms left
