The table below shows the amount of money, in hundreds of dollars, Elliot has saved after different numbers of years: Identify the function that represents Elliot's savings and the amount that Elliot will have saved in 9 years.

y = 15x, in 9 years he will have saved $13,500
y = x + 15, in 9 years he will have saved $2,400
y = 6x, in 9 years he will have saved $5,400
y = x + 90, in 9 years he will have saved $9,900

Table:
Years (x)                                      1     2     3     4     5     6 
Money (y) (hundreds of dollars) 15   30   45   60   75   90

y = 15(x)
y = 15(9)
y = 135 hundreds of dollars

y = 15x, in 9 years he will have saved $13,500

−1 1/2−(+3 1/2)−(−5/8)

Answers

Answer:

-35/8

Step-by-step explanation:

−1 1/2−(3 1/2)−(−5/8)

Convert all fractions into improper fractions:

- 3/2 - (7/2) - (-5/8)

Make all denominators:

(-3*4)/(2*4)

-12/8 - ((7*4)/(2*4)) - (-5/8)

-12/8 - ((28)/(8)) + 5/8

-35/8

What is the inverse of the function f(x)=1/9x+2

Answers

Answer:

f^(-1)(x)=9x-18

Step-by-step explanation:

we have

f(x)=(1)/(9)x+2

Let

y=f(x)

y=(1)/(9)x+2

Exchange variables x for y and y for x

x=(1)/(9)y+2

Isolate the variable y

x-2=(1)/(9)y

y=9(x-2)

y=9x-18

Let

f^(-1)(x)=y

f^(-1)(x)=9x-18 -------> inverse function
f(x) = 1/9x+2

-2 from both sides

f(x)-2 = 1/9x

*2 to both sides

9(f(x)-2) = x

replace 'f(x)' with 'x'

9(x-2) = f(x^-1)

simplify and reverse sides

f(x)^-1 = 9x-18
