Answer:

2=k^1/x

3=k^1/y

12=k^1/z.......we get...

(atq)------k^1/x=k^1/y=k^1/z

(*a^m=b^m......b=a)

~1/x=1/y=1/z

1/z=1/y+1/x×2

(12=3+2×2)

1/z=1/y+2/x.....proved

Which function is a linear function?
Anettt [7]

For this case we have that by definition, a linear function is of the form

y = mx + b

We have the following options:

A) 1-3x ^ 2 = -y

Rewriting:

y = 3x ^ 2-1

It's a quadratic function!

B) y + 7 = 5x

Rewriting:

y = 5x-7

It's a linear function!

C)x ^ 3 + 4 = y

Rewriting:

y = x ^ 3 + 4

It's a cubic function.

D) 9 (x ^ 2-y) = 3

Rewriting:

9x ^ 2-9y = 3\\9y = 9x ^ 2-3\\y = x ^ 2- \frac {3} {9}

It's a quadratic function!

E)y-x ^ 3 = 8

Rewriting:

y = x ^ 3 + 8

It's a cubic function!

Answer:

The linear function is option B
