Which of the following expressions is the inverse of the function y=3x+4
zubka84 [21]
To find the inverse of a function, we swap x and y then solve for y
So with this, we take y = 3x + 4 and make it x = 3y + 4. Now we solve for y
x = 3y + 4
Subtract 4 from both sides
x - 4 = 3y
Divide both sides by 3
\frac{x-4}{3} =y

Find the area of the regular polygon.<br>Round to the nearest tenth.<br>16 ft​
Sladkaya [172]

<u>Given</u>:

Given that the side of the regular polygon is 16 feet.

We need to determine the area of the polygon.

<u>Area of the polygon:</u>

The area of the polygon can be determined using the formula,

Area =\frac{s^2 n}{4 \ tan \frac{180}{n}}

where n is the number of sides,

s is the side length.

Substituting n = 3 and s = 16, we get;

Area =\frac{16^2 (3)}{4 \ tan \frac{180}{3}}

Simplifying, we get;

Area =\frac{(256) (3)}{4 \ tan \ 60}

Area = \frac{768}{6.928}

Dividing, we get;

Area = 110.85

Rounding off to the nearest tenth, we have;

Area = 110.9

Thus, the area of the regular polygon is 110.9 square units.

If 3x−y=12, what is the value of 8x/2y ? A) 212 B) 44 C) 82 D) The value cannot be determined from the information given.
Stella [2.4K]

Answer:

D) The value cannot be determined from the information given

Step-by-step explanation:

If 3x−y=12, what is the value of 8x/2y ?

We can progress till:

  • 3x-y=12
  • y= 3x-12
  • 8x/2y= 4x/y= 4x/(3x-12),

we need the value of x to determine the result.

So the answer is the last choice
