Answer:

f^-1(x)= 1/3 x

Step-by-step explanation:

y = 3x

To find the inverse, exchange x and y

x = 3y

Solve for y by dividing by 3 on each side

x/3 = 3y/3

1/3x = y

The inverse is 1/3x

Schaum earns (x4 + 16x) every month. His wife earns (3x4 + 11x) every

damaskus [11]

Given:

Schaum's earnings in a month = $x^4+16x$

His wife's earnings in a month = $3x^4+11x$

Where x is the number of working days in a month.

To find:

The total earnings in a month.

Solution:

We know that,

Total earnings = Schaum earnings + His wife's earnings in a month

$=x^4+16x+3x^4+11x$

$=(x^4+3x^4)+(16x+11x)$

$=4x^4+27x$

Therefore, the correct option is A.

Write an equation perpendicular to the line y=2/3x+6, and passing through the point (-3,6)

shepuryov [24]

Answer:

y = -3/2x + 1 1/2

Step-by-step explanation:

the slope would be -3/2 because you have to find the reciprocal and switch the sign. To find the y intercept you would plug in the points to the equation.

6 = -3/2(-3) + b

6 = 4.5 + b

1.5 = b
