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

Answer:

Let x = the number

A negative number is 42 less than its square ⇒

x = x2 - 42

x2 - x - 42 = 0

(x - 7)(x + 6) = 0

x = 7 or -6

But since it is given that x is negative, the final answer is x = -6.

A function can be represented on graphs and a graph can also be represented as a function.

The values of f(x) = 3 are -1 and -4

The graph of the function is given as:

[tex]\mathbf{y = f(x)}[/tex]

Substitute 3 for y

[tex]\mathbf{f(x) = 3}[/tex]

From the graph;

x = -4 and x = -1, when f(x) = 3

This means that:

The solutions for f(x) = 3 are x = -4 and x = -1

Answer:

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)

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.

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.
