Answer: Your question options are not legible but the inverse of the function is f-1(x) = (x + 2) / 2

Step-by-step explanation:

y = 2x + 2

Make x the subject of formula:

2x = y - 2

x = (y - 2) / 2

Now substitute y for x:

(x - 2) / 2

Y = (x - 2) / 2 is the inverse equation of the above graph.

Simplify. Assume that no denominator is equal to zero. ([3^2]^3g^3h^4)^2
mariarad [96]

Answer:

531,441·g^6·h^8

Step-by-step explanation:

The operative rule of exponents is ...

(a^b)^c = a^(b·c)

Working from the inside out, according to the order of operations, we get ...

= (9^3·g^3·h^4)^2

= 729^2·g^(3·2)·h^(4·2)

= 531,441·g^6·h^8

There are 160 people in a grade. The ratio of boys to girls is 3 to 5. Which proportion can you use to find the number x of boys
Nezavi [6.7K]

Answer:

60 boys

Step-by-step explanation:

boys : girls = 3 : 5

Total number of people = 160

Let y = common factor:

Therefore, 3y + 5y = 160

⇒ 8y = 160

⇒ y = 160 ÷ 8 = 20

Boys = 3y = 3 x 20 = 60

Girls = 5y = 5 x 20 = 100

So there are 60 boys and 100 girls

Evaluate lim x=π/4(3x - tanx)​
Karo-lina-s [1.5K]

Answer:

 \lim_{x \to\frac{\pi }{4} } (3x-tanx) =  3(\frac{\pi }{4}  )

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that

         \lim_{x \to\frac{\pi }{4} } (3x-tanx)

  =  \lim_{x \to\frac{\pi }{4} } (3x) -  \lim_{x \to\frac{\pi }{4} }  tanx)

 = 3(\frac{\pi }{4} )+tan(\frac{\pi }{4} )

=  3(\frac{\pi }{4} )+ 1 )

=  3(\frac{\pi }{4}  )
