Find all whole values for y for which the double inequality is true: a) −5b) 28

kolezko [41]

Answer: -5 ≤ y ≤ 28 or y = -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28

Step-by-step explanation:

This is the double inequality equation:

a ≤ y ≤ b

Plug in your values:

-5 ≤ y ≤ 28

y can be greater than or equal to -5 but has to be less than or equal to 28.

So, here are all of the values:

y = -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28

-5 ≤ y ≤ 28

Hope this helps! :)

What is the inverse of the function f(x) = 2x – 10?

strojnjashka [21]

Answer:

see explanation

Step-by-step explanation:

let y = f(x) then rearrange making x the subject

y = 2x - 10 ( add 10 to both sides )

y + 10 = 2x ( divide both sides by 2 )

$\frac{y+10}{2}$ = x

Change y back into terms of x

$f^{-1}$ (x) = $\frac{x+10}{2}$

What is the equation of the function that is graphed as line a

levacccp [35]

Answer:

Step-by-step explanation:

From the graph we have:

y-intercept = -1

x-intercept = -1

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

Therefore we have: y = mx - 1

Put the coordinates of the x-intercept to the equation:

(-1, 0) → x = -1 and y = 0:

0 = -1m - 1 add m to both sides

0 + m = -m + m - 1

m = -1

Finally we have the equation:

y = -1x - 1

Describe each of the following values as (A) a discrete random variable, (B) a continuous random variable, or (C) not a rand

ANEK [815]

Answer:

1. Is a continuous random variable

2. Is a discrete random variable

3. Is not a random variable

Step-by-step explanation:

1. The exact Weight of quarters in circulation in the united states is a continuous random variable. This is because a random variable such as this can take uncountable and infinite number of values.

2. The shoe sizes if humans is an example of discrete random variable. This is a discrete random variable because it has countable number of values.

3. Political party affiliation is not a random variable.

Thank you!
