Solution:

2/x     +  y/4     =    3/2

Let's solve for y.

2/ x    +   y/ 4    =     3/ 2

Step 1: Multiply both sides by 4x.

xy     +    8    =     6x

Step 2: Add -8 to both sides.

xy    +    8    +    −   8    =    6x    +    −8

xy    =   6x   −    8

Step 3: Divide both sides by x.

xy/x     =       6x    -    8/x

Answer   =====>  y   =    6x     -   8/x




When Graph:  

y     =     6    -   8/x

x- Intercepts Points:

4/3,    and       0




Equation====>  2:

Let's solve for x.

2/ x      +    y/ 4     =      3/ 2

Step 1: Multiply both sides by 4x.

xy     +    8     =    6x

Step 2: Add -6x to both sides.

xy    +    8    +    − 6x    =     6x     +     −  6x

xy    −     6x    +    8    =    0

Step 3: Add -8 to both sides.

xy     −     6x    +    8    +    −    8      =     0    +       −8

xy     −    6x      =   −8

Step 4: Factor out variable x.

x(y   −   6)    =    −8

Step 5: Divide both sides by y-6.

x( y   -    6 )/y   -  6       =        -8/ y    -   6

Answer  ======>      x     =       -8/y    -   6







Hope that helps!!!!                                  : )

Find the perimeter of the figure to the nearest hundredth.
Kryger [21]

Hello!

Your answer should be 26.85.

We can use the formula of pi d or 2 pi r for the circumference.

You would get 5 pi.

But since its not a full circle you would divide it in half and get 2.5 pi.

2.5 pi is equal to 7.85.

Now we can use the equation 7.85 + 7 + 7 + 5

That would equal our answer... 26.85!

Hope this helps!

box with a square base and open top must have a volume of 4,000 cm3. Find the dimensions of the box (in cm) that minimize the am
Naya [18.7K]

Answer:

Hence the width, length is 20 cm and height is 10 cm

Step-by-step explanation:

Since the box has a square base, let length = width = x. Also, let the height = y, therefore:

The volume of box = width * length * height

4000 = x * x * y

4000 = x²y

y=4000/x²

The surface area (SA) = area of the base + sum of the area of each side

SA = x² + xy + xy + xy + xy

SA = x² + 4xy

substitute y = 4000/x²

SA = x² + 4x(4000/x²)

SA = x² + 16000/x

Taking the derivative:

SA' = 2x - 16000/x²

making SA' = 0:

0 = 2x - 16000/x²

2x = 16000/x²

2x³ = 16000

x³ = 8000

x = 20 cm

y = 4000 / x² = 4000 / 20² = 10 cm

Hence the width, length is 20 cm and height is 10 cm

Simplify the rational expression. State any restrictions on the variable. t^2-4t-32/t-8
Leno4ka [110]

1. Factor the expression t^2-4t-32:

t^2-4t-32=(t-8)(t+4).

2. Since t-8 is placed in the denominator of the given expression, then t\neq 8.

3. Now the expression can be simplified:

\dfrac{t^2-4t-32}{t-8}=\dfrac{(t-8)(t+4)}{t-8}=t+4.
