What is the value of x?

vivado [14]

Answer:

x = 52/3

Step-by-step explanation:

3x / 7x = (3x+7) / (3x+7+5x-8)

3/7 = (3x+7)/(8x - 1)

Cross multiply

7(3x+7)=3(8x-1)

21x + 49 = 24x - 3

-3x = -52

x = 52/3

Need explanation 20 points The function f is such that f(x) = 2x - 6 Find f^-1(x)

Dvinal [7]

HEYA! <3

Explanation :

GIVEN :

f(x) = 2x - 6

TO FIND :

Inverse of f(x) i.e $f ^{ - 1} (x)$

SOLUTION :

FOLLOW THESE THREE STEPS :

LET Y = f(x)

$\longrightarrow \tt{y = 2x - 6}$

$\longrightarrow{ \tt{ \: 2x - 6 = y}}$

MAKE X A SINGLE TERM IN LHS SIDE

$\longrightarrow{ \tt{2x = y + 6}}$

$\longrightarrow{ \tt{x = \frac{y + 6}{2} }}$

INTERCHANGE THE VALUE OF X AND Y

$\longrightarrow{ \tt{y = \frac{x + 6}{2} }}$

Hence ,

$\boxed{ \boxed{ {f}^{ - 1} (x) = \sf{ \bold{ \frac{x + 6}{2} }}}}$

Hope I helped!

Have a wonderful day / night !

An architect is designing a building that is 157 feet wide. Solve for how tall the building must be if the

lilavasa [31]

254.031336 feet tall

Since the golden ratio is 1.61803398875, we just multiply 157 by it... since 157*1.61803398875=254.031336, we can assume this is the correct answer. Simplified it would be 254.03
