Answer:

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1-y}{1+x}[/tex]

Step-by-step explanation:

Differentiate xy using the product rule, then

Given

x - y = xy

1 - [tex]\frac{dy}{dx}[/tex] = x. [tex]\frac{dy}{dx}[/tex] + y. 1 = x[tex]\frac{dy}{dx}[/tex] + y ( subtract 1 from both sides )

- [tex]\frac{dy}{dx}[/tex] = x [tex]\frac{dy}{dx}[/tex] + y - 1 ( subtract x [tex]\frac{dy}{dx}[/tex] from both sides )

- [tex]\frac{dy}{dx}[/tex] - x [tex]\frac{dy}{dx}[/tex] = y - 1 ( multiply through by - 1 )

[tex]\frac{dy}{dx}[/tex] + x[tex]\frac{dy}{dx}[/tex] = 1 - y

[tex]\frac{dy}{dx}[/tex] (1 + x) = 1 - y ← divide both sides by (1 + x)

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1-y}{1+x}[/tex]

The differentiation of the function x - y = xy is dy/dx = (1-y)/(x+1).

Differentiation is a method of finding the derivative of a function.

It shows instantaneous rate of change in a function.

The given expression is,

x - y = xy

Differentiate with respect to x,

d/dx (x-y) = d/dx (xy)

Use multiplication formula for differentiation,

d/dx(ab)= a.db/dx+da/dx.b,

1 - dy/dx =  x.dy/dx + y. 1

1 - dy/dx = x.dy/dx + y

1 - y =x.dy/dx + dy/dx

1 - y = (x+1).dy/dx

dy/dx = (1-y)/(x+1)

The differentiation of the function x - y = xy is dy/dx = (1-y)/(x+1).

Answer:

y = -3x + 4

Step-by-step explanation:

So the -3 is the slope and the slope always has an x and the y intercept is b which is 4

Answer:

y = -3x + 4

Step-by-step explanation:

slope-intercept form: y = mx + b

Note that: m = slope

y- intercept = b

m = slope = -3

y-intercept = b = 4

Plug in the corresponding number to the corresponding variables:

y = mx + b

y = -3x + 4 is your answer.

Answer:

y = -7

Step-by-step explanation:

As the slope is m = 0, that means there is no slope. All values of x in the domain will always output -7. Therefore, your equation would be y = -7.

Answer:

y = -7

Step-by-step explanation:

Use the formula:

y = mx + b

Where m is the slope and b is the y-intercept.

The slope of the equation is equal to 0.

The y-intercept is at (0, -7)

y = (0)x + -7

y = -7

The equation of the line is y = -7.

Total interior angles in a triangle=180 degrees

That is: 3x + 10 + 5x - 1 + x =180

9x+9=180

9x=180-9

9x=171

x=171/9

x=19

Therefore

Angle A =67 degrees

Angle B= 94 degrees

Angle C = 19 degrees

Answer:

The height of the triangle is 24 cm.

Answer:

The answer is A

Step-by-step explanation:

The formula used to find the area of a triangle is 1/2base *height

The base is 16 so half of 16 is 8 then multiply it with the height 8 to get 64.

Area of obtuse triangle is 64 sq. units

"A triangle whose any one of the angles is an obtuse angle or more than 90 degrees, then it is called obtuse-angled triangle or obtuse triangle."

Given

Base of triangle = 16

Height of triangle = 8

Formula to find the area of obtuse triangle

A = [tex]\frac{1}{2}[/tex] × [tex]base[/tex] × [tex]height[/tex]

A = [tex]\frac{1}{2}[/tex] × [tex]16[/tex] × [tex]8[/tex]

A = 8 × 8

A = 64

Hence, Area of obtuse triangle is 64 sq. units

answer:

how many can are needed to move?

Step-by-step explanation:

Answer:

-8 ÷ (x + 3)

Step-by-step explanation:

So quotient means that you're dividing, so put a ÷

Next, it says the dividend, or the part being divided is -8, so now you have this: -8 ÷

Lastly, it says the divisor, or the part doing the dividing, is a quantity equal to the sum of "some number" (we'll use x) and 3. Since the divisor is one quantity collectively, you have to put it in parentheses.

This gives you: (x + 3)

When you put it all together, you get -8 ÷ (x + 3).

This can also be written as a fraction: -8/x+3.

Area of patio = 12 x 16

                      = 192 square feet

Cost = 192 x 8

        = $1536

Answer:

Step-by-step explanation:

Given equation of the line is,

y = -x + 1

We will get the output values (y-values) from the given equation for different input values (x-values).

For x = 0,

y = 0 + 1

y = 1

For x = -1,

y = -1 + 1

y = 0

For x = -6,

y = -6 + 1

y = -5

So the table of the ordered pairs will be,

x        0         -1          -6            

y       1           0         -5
