Answer:

Step-by-step explanation:

let the no. be 'x'

By question,

2x-8=6

or, 2x =6+8

or,2x = 14

or,x = 7

therefore, the no. is 7.

The line which passes through -2,5 and 6,8

babunello [35]

Answer:

y=(3/8)x+5.75

Step-by-step explanation:

y=mx+b

m=slope

b=y-intercept

m=(8-5)/(6+2)=3/8

y=mx+b

5=3/8(-2)+b

5=-3/4+b

b=5.75

y=mx+b

y=(3/8)x+5.75

The inverse function theorem says

$\dfrac{\mathrm df^{-1}}{\mathrm dx}(16)=\dfrac1{\frac{\mathrm df}{\mathrm dx}(f^{-1}(16))}$

We have

$f(x)=x^2+4x-5$

defined on $x>-2$ , for which we get

$f^{-1}(x)=-2+\sqrt{x+9}$

and

$f^{-1}(16)=-2+\sqrt{16+9}=3$

The derivative of $f(x)$ is

$f'(x)=2x+4$

So we end up with

$\dfrac{\mathrm df^{-1}}{\mathrm dx}(16)=\dfrac1{\frac{\mathrm df}{\mathrm dx}(3)}=\dfrac1{10}$
