Acc. to midpoint theorem,

15={(2x+9) + (4x-15)}/2
⇒ 30=2x+9+4x-15
⇒ 30-9+15=6x
⇒ 36/6=x
⇒6=x

WZ= 4x-15
=4*6-15
=24-15=9

Answer:

Step-by-step explanation:

Given that:

Ava bring 34 food to the picnic

Kate bring 16 food to the picnic

JIn brings 112 food to the picnic

To enter these digits by applying equivalent fractions with a denominator of 12;

Their respective numerical expression is:

Ava = $\dfrac{34}{12}$

Ava brought $2 \dfrac{5}{6}$ food to the picnic

Kate = $\dfrac{16}{12}$

Kate brought $1 \dfrac{1}{3}$ food to the picnic

Jin = $\dfrac{112}{12}$

Jin brought $9 \dfrac{1}{3}$ food to the picnic

If f(x) = 9x – 8, which of the following is the inverse of f(x)?

zheka24 [161]

Answer: $f^{-1}$ (x) = $\frac{x+8}{9}$

Step-by-step explanation:

f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes

y = 9x - 8 , then make x , the subject of the formula ,

9x = y + 8

x = $\frac{y+8}{9}$

Finally , replace x , with $f^{-1}$ (x) and y with x , so we have

$f^{-1}$ (x) = $\frac{x+8}{9}$
