Answer:

X= 7

Step-by-step explanation:

x+x+2+3x-6=31 Combine x's

2x+2+3x-6=31 Continue to combine x's

5x+2-6=31 Combine whole numbers

5x-4=31 Add 4 to both sides

5x=35 Divide by 5

x=7

Caroline rolls a fair dice 480 times. How many times would Caroline expect to roll a six?

Gnom [1K]

A fair die has 6 sides so a 1/6 chance for each number
So divide 480/6= 80
80 times for each number, 80 for 6

Need help with this function problem

kotykmax [81]

Answer:

see attached

Step-by-step explanation:

To find the inverse function, solve ...

x = f(y)

x = (y^7)/7 -4 . . . . . . . use the definition of f(x)

x +4 = (y^7)/7 . . . . . . add 4

7(x +4) = y^7 . . . . . . multiply by 7

(7(x +4))^(1/7) = y . . take the 7th root

The inverse function is the one shown in the attachment.

What is 0 + y when y = -11

Mashutka [201]

when y = -11, 0 + y is equal to -11.

the question is asking us to add 0 to the given value of y. the given value of y is -11, so place -11 into 0 + y and you get 0 + -11. since you are adding zero, you are making no changes to the y value, so it stays at -11.
