Pablo is training for a marathon . He ran 5 4/8 miles on Friday 6 5/8 on sat and 7 4/8 on Sunday how many miles did he run A. 1 5/8
B. 12 1/8
C. 19 4/8
D. 19 5/8

Answers

If you would like to know how many miles did Pablo run, you can calculate this using the following steps:

5 4/8 miles on Friday + 6 5/8 miles on Saturday + 7 4/8 miles on Sunday = 5 4/8 + 6 5/8 + 7 4/8 = 44/8 + 53/8 + 60/8 = 157/8 = 19 5/8 miles

The correct result would be D. 19 5/8 miles.

Multiple choice?

Step-by-step explanation:

The inverse of the function f(x) = x + 10 is shown.h(x) = 2x –

What is the missing value?

Answers

we have

$f(x) = (1)/(2)x + 10$

Step $1$

Let

y=f(x)

$y = (1)/(2)x + 10$

Exchange the variable x for y and variable y for x

$x = (1)/(2)y + 10$

Clear variable y

Multiply by $2$ both sides

$2x = y + 20$

$y = 2x-20$

Let

$f(x)^(-1) =y$

$f(x)^(-1)=2x-20$

therefore

the answer is

the inverse of the function is $f(x)^(-1)=2x-20$

the missing value is $20$

Answer:

The Given function is

y= x + 10

To find the inverse of function , we use the following procedure

x=y-10

Now, replace x by y and y by x, we get the inverse of function

y=x -10 , is the inverse of the function, y=x+10.

As, it is given that inverse of f(x) is h(x)

Also, h(x)= 2 x - k-------(1)

Inverse of f(x)=x+10 is ,y= x-10, that is 2 y=2 x- 20------(2)

Comparing 1 and 2, gives

h(x)=2 y

-k=-20

k=20
