What is the value of b in the equation below? 9^-8 x 9^-2 = a^b <br> -10 <br> -6 <br> 9 <br> 16

lys-0071 [83]

Answer:

-10

Step-by-step explanation:

9^-8 x 9^-2 = a^b

We know that x^y * x^z = x^(y+z)

9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)

a= 9

b = -10

Which equation is the inverse of 2(x-2)squared=8(7+y)

dsp73

Answer:

$f^{-1}(x)=2(+/-)2\sqrt{(7+x)}$

Step-by-step explanation:

we have

$2(x-2)^{2}=8(7+y)$

step 1

Exchange x for y and y for x

$2(y-2)^{2}=8(7+x)$

step 2

isolate the variable y

$(y-2)^{2}=4(7+x)$

take the square root both sides

$y-2=(+/-)\sqrt{4(7+x)}$

$y=2(+/-)\sqrt{4(7+x)}$

step 3

Let

$f^{-1}(x)=y$

$f^{-1}(x)=2(+/-)\sqrt{4(7+x)}$

$f^{-1}(x)=2(+/-)2\sqrt{(7+x)}$ ----> equation of the inverse
