Answer:

f

−

1

(

x

)

=

9

x

+

5

6

−

x

Step-by-step explanation:

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=9x+56−x f - 1 ( x ) = 9 x + 5 6 - x is the inverse of f(x)=6x−5x+9 f ( x ) = 6 x - 5 x + 9 .

2(n-1)+ 4n= 2 (3n -1)
muminat

Answer:

Infinitely many solutions.

Step-by-step explanation:

2 (n - 1) + 4n = 2 (3n - 1) Let's simplify this to solve it.

2n - 2 + 4n = 6n - 2 Distribute 2(n-1) and 2(3n-1)

2n + 4n - 2 = 6n - 2 Rearrange the left side of the equation.

6n - 2 = 6n - 2 Add 2n + 4n.

-6n        -6n Subtract 6n from both sides.

-2 = -2

the answer is infinitely many solutions, meaning that n can be any real number.

The perimeter of a rectangle is 354 km. Its side lengths are 81 km, 81 km, and 96 km. The fourth side length is given as "f" km.
k0ka [10]

The fourth side = f, now let's solve for f

  • f + 81 + 81 + 96 = 354

  • f + 258 = 354

  • f = 354 - 258

  • f = 96

value of fourth side = f = 96 km

How do you write an equation in slope- intercept form of the line passing through the given points ? (0,7), (1,9)
Airida [17]

y = 2x + 7

the equation of a line in ' slope-intercept form ' is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the ' gradient formula '

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 7 ) and (x₂, y₂ ) = (1, 9)

m = \frac{9-7}{1-0} = 2

given the point (0, 7 ) then c = 7

y = 2x + 7  ← in slope-intercept form

Jim wants to know how much his family spends on water for showers. Water costs $1.50 for 1,000 gallons. His family averages 4 sh
Setler [38]
Since the family spends ten minutes on average per shower and there is 2.5 gallons spent per minute, 25 gallons are used per shower and with 4 shows per day, 100 gallons are used per day, so in 30 days they use 3,000 gallons of water, since water costs $1.50 per 1000 gallons, showering only costs them $4.50 per month
