Step-by-step explanation:

x = 1 - i sqrt(2) ^ y = 10 + i sqrt(2)

x = 1 + i sqrt(2) ^ y = 10 - i sqrt(2)

Answer:

Step-by-step explanation:

y = 11 - x  ----------(I)

y  = 2x² - 4x + 6 -----------(II)

Substitute y = 11- x in (II)

11 - x = 2x² - 4x + 6

0 = 2x² - 4x + x + 6 - 11

0 = 2x² - 3x - 5

2x² - 3x  - 5 = 0

Sum = -3

Product = -10

Factors = -5 , 2

2x² - 5x + 2x - 5 = 0

x(2x - 5) + (2x - 5) = 0

(2x -5 )(x +1)=0

2x - 5 = 0  ; x + 1 = 0

2x = 5      ; x = -1

  x = 5/2

When x = -1   ;  y = 11 - (-1) = 11 + 1 = 12

[tex]When x = \dfrac{5}{2} ; y = 11- \dfrac{5}{2}= \dfrac{22}{2}- \dfrac{5}{2}= \dfrac{17}{2}[/tex]

Solution:  (-1 , 12)  and (5/2 , 17/2)

The equivalent ratio of 9:25 is 36:100.

Ratio expresses the degree of proportionality between two or more numbers. It expresses the number of times one number is contained in another number.  

In order to make the ratios equal, the relationship that exists between 9 and 36 has to be determined. 36 is a multiple of 9. It is 9 multiplied by 4. So, in order to make the ratios equal, multiply, 25 by 4.

25 x 4 = 100

Answer: D) y = -3x + 5

Step-by-step explanation:

Move x.

3y = -9x + 15

Divide by 3.

y = -3x + 5

Hope it helps :) and let me know if you want me to elaborate.

Answer:

D. y = -3x + 5

Step-by-step explanation:

Subtract 9x from both sides

3y = 15 - 9x

y = 15/3 - 9x/3

y = 5 - 3x

y = -3x + 5

Step-by-step explanation:

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Answer:

  dy/dx = y/(2x)

Step-by-step explanation:

The product formula can be used, along with the power rule.

  d(uv) = du·v +u·dv

__

  d(y^2/x) = d(18)

  2y·dy/x -y^2/x^2·dx = 0

  2x·dy -y·dx = 0 . . . . . . . . multiply by x^2/y

  dy/dx = y/(2x) . . . . . . . . add y·dx, divide by 2x·dx

Step-by-step explanation:

Justice needs $72 to fence in his garden.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Justice needs 24 feet of fencing to surround his garden.

The fencing is priced at $0.25 per inch.

Since, 1 foot = 12 inch

Hence, 24 feet = 24 x 12 inch = 288 inch.

Cost of the fencing in one inch = $0.25

So, Cost of the fencing in 288 inch = 288 x 0.25

                                                      = $72

Thus, Justice needs $72 to fence in his garden.

k = -1

Step-by-step explanation:

Plug the known values into the linear equation:

[tex]2x + ky = 8\\2(6) + k(4) = 8\\12 + 4k = 8\\[/tex]

Subtract 12 from both sides to isolate 4k:

Divide both sides by 4:

How can you determine if the relationship is a direct variation or an inverse variation?

Direct Variation: Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases.
