The relation between the values described for x and g(x) are satisfied by the last table. When x = 1; g(x) = 2, x = 2; g(x) = 8 and x = 3; g(x) = 14.

The given two functions are,

f(x) = 3x - 4

g(x) = f(2x)

Here by, putting x as 2x in f(x),

f(2x) = 3(2x) - 4

f(2x) = 6x - 4

Because, g(x) = f(2x),

g(x) = 6x - 4

Now, putting the value of x in g(x) as 1, 2, and 3.

Putting x = 1 in g(x),

g(1) = 6(1)-4

g(1) = 2

Now, putting x = 2 in g(x)

g(2) = 6(2) - 4

g(2) = 12 - 4

g(2)  = 8

Finally, putting x = 3 in g(x),

g(3) = 6(3) - 5

g(3) = 18 - 4

g(3) = 14

So, as we can see from the options, the last of the provided four tables is satisfying the values of x and g(x).

Two numbers total 63 and have a difference of 31. Find the two numbers
Anastaziya [24]

Answer: 47 and 16

Step-by-step explanation:

- Make Two Equations

x + y = 63

x - y = 31

- Set one of the equations equal to one of the variables

x + y = 63

x = 31 + y

- Substitute the equation back into the other one

(31 + y) + y = 63

31 + 2y = 63

2y = 32

y = 16

- Substitute the answer back into the equation

x + y = 63

x + 16 = 63

x = 47

PART A: Maria rented a coat at $285 for 3 days. If she rents the same coat for 60 days, she has to pay a total rent of $510. Wri
Dmitriy789 [7]
<span>1) Name the variables

Number of days: x

rent: y

2) state the initial points

   x           y
days        $

  3           285

60           510


3) assume linear relation:

=> (y - yo) / (x - xo) = (y1 - yo) / (x1 - xo)

=> (y - 285) / (x - 3) = (510 - 285) / (60 - 3)

=> (y - 285) / (x - 3) = 225 / 57 = 75 / 19

=> 19 (y - 285) = 75 (x - 3)

=> 19y - 19*285 = 75x - 75*3

=> 19y - 75x = 5415 - 225

=> 19y  - 75x = 5190

=> standar form = -75x + 19y = 5190


PART B: Write the equation obtained in Part A using function notation.

-75x + 19y = 5190

=> 19y = 5190 + 75x

=> y = 5190/19 + (75/19)x

=> function notation = f(x) = (75/19)x + 5190 / 19

PART C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.

1) Coordinate axes:

x: number of days

y: rent

2) draw the two given points: (3,285) and (60, 510)

3) draw the line that joins those points from the interception of the y-axis until some points further (60, 510).
