#1,

The domain is all of the x-values.

The x-values of the set are: 2, 15, 21, 24

Your answer is C.

#2,

Part A)
Yes, the data in the table represents a function because each x-value has exactly one y-value. Also, the function passes the vertical line test.

Part B)
f(x) = 5x - 21
f(11) = 5(11) - 21
f(11) = 55 - 21
f(11) = 34

The table has a y-value of 8, when x = 11.

Therefore, f(x) = 5x - 21 has a greater value than the table when x = 11

Part C)
f(x) = 99
f(x) = 5x - 21

5x - 21 = 99
5x = 120
x = 24

The value of x is 24.

A quantity and its 2/3 are added together and from thesum 1/3 of the sum is subtracted, and 10 remains.What is the quantity?

musickatia [10]

Answer:

$14\frac{1}{3}$

Step-by-step explanation:

Let's write this out as an equation. Let the unknown quantity be x:

$x+\frac{2}{3} - \frac{1}{3} (x+\frac{2}{3}) = 10\\\\3x+2-x -\frac{2}{3} = 30\\\\9x+6-3x-2=90\\\\6x= 86\\\\x = \frac{86}{6} =\frac{43}{3} =14\frac{1}{3} \\$
