Answer:

3, 15, 14

Step-by-step explanation:

x + 5x + ( 5x -1) = 32

11x - 1 = 32

11x = 32 + 1

11x = 33

11x/11 = 33/11

x = 3

therefore

the first number is 3

the second is 5 × 3 = 15

the third number is 15 - 1 = 14

if (20,14) is an ordered pair of the inverse of f(x) which of the following is an ordered pair of the function f(x)
Strike441 [17]
<h3>(14, 20) is the ordered pair of the function f(x)</h3>

<em><u>Solution:</u></em>

Given that,

(20, 14) is an ordered pair of the inverse of f(x)

We have to find the ordered pair of the function f(x)

In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain

To find the ordered pair of the function f(x),  we swap the variables x and y

(y, x) of inverse of f(x) becomes (x, y) of f(x)

Therefore, (14, 20) is the ordered pair of the function f(x)

Graph the function. Describe its position relative to the graph of the indicated basic function.
masya89 [10]

Answer:

The answer is (b) moved right 3 units and moved down 3 units

Step-by-step explanation:

∵ f(x) = 4^x ⇒ red in the graph

∵ f(x) = 4^(x-3) - 3 ⇒ blue in the graph

∵ x  becomes x - 3 ⇒ means:

 The graph moved right 3 units

∵ f(x) = 4^x becomes 4^(x-3) - 3 ⇒ means:

  The graph moved down 3 units

∴ The answer is (b)
