Answer:

3/2

Step-by-step explanation:

The multiplicative inverse also known as reciprocal implies it is something that is the opposite.

The given value is 2/3, so the opposite would just mean you flip the numerator and denominator. Thus, the reciprocal of 2/3 is 3/2.

Answer:

3/2

Step-by-step explanation:

The multiplicative inverse is also known as a reciprocal.

The reciprocal of 2/3 is 3/2.

1 ÷ 2/3 = 1 × 3/2

Reciprocals are always used when you divide by a fraction.

-1/2(-3/2x + 6x + 1) - 3

Simplify.

(3/4x - 3x - 1/2) - 3

Get rid of the parenthesis.

3/4x - 3x - 1/2 - 3

Add like terms.

(3/4x - 3x) + (-1/2 - 3)

Simplify.

-2 1/4x + (-3 1/2)

Get rid of the parenthesis.

-2 1/4x - 3 1/2

Hope I helped! :)

Find a formula for the described function. An open rectangular box with volume 3 m3 has a square base. Express the surface area

Alex73 [517]

Answer:

$SA(x) = x^2 + \frac{12}{x}$

Step-by-step explanation:

Given

$V = 3m^3$ --- volume

$x \to base\ length$

$y \to height$

Required

The surface area as a function of base length

The volume (V) is calculated as:

$V = Base\ Area * Height$

$V = x*x*y$

$V = x^2*y$

Make y the subject

$y = \frac{V}{x^2}$

Substitute 3 for V

$y = \frac{3}{x^2}$

The surface area of the open box is:

$SA = x^2 + 2xy+2xy$

$SA = x^2 + 4xy$

Substitute: $y = \frac{3}{x^2}$

$SA = x^2 + 4x*\frac{3}{x^2}$

$SA = x^2 + 4*\frac{3}{x}$

$SA = x^2 + \frac{12}{x}$

Hence, the function is:

$SA(x) = x^2 + \frac{12}{x}$
