What makes the equation true?<br>20- 4=6+4+?
Ede4ka [16]
The answer would be 6 because 20-4=16. So to make it equal to that 6+4=10. Since it is not you need 6 more so answer is 6.

F(x) = ^3 Squared 3x g(x) = 32 + 2 Find (f/g) (x)
Lunna [17]

By applying the <em>functional</em> theory related to <em>binary</em> operations of functions, we conclude that the resulting expression is equal to (f \,\circ \,g) (x) = \frac{\sqrt[3]{3\cdot x} }{3\cdot x + 2}.

<h3>How to find the expression of a division between two functions</h3>

In <em>functional</em> theory, there are five operations that can be used between two functions:

  1. Addition - (f + g) (x) = f(x) + g(x)
  2. Subtraction - (f - g) (x) = f(x) - g(x)
  3. Multiplication - (f · g) (x) = f(x) · g(x)
  4. Division - (f/g) (x) = f(x) / g(x)
  5. Composition - (f ο g) (x) = f (g (x))

In this question we are asked to derive the expression of the division between two functions given. If we know that f(x) = \sqrt[3]{3\cdot x} and g(x) = 3 · x + 2:

(f \,\circ \,g) (x) = \frac{\sqrt[3]{3\cdot x} }{3\cdot x + 2}

By applying the <em>functional</em> theory related to <em>binary</em> operations of functions, we conclude that the resulting expression is equal to (f \,\circ \,g) (x) = \frac{\sqrt[3]{3\cdot x} }{3\cdot x + 2}.

<h3>Remark</h3>

The statement is poorly formatted and reports many typing mistakes. Correct statement is shown below:

Let f(x) = \sqrt[3]{3\cdot x} and g(x) = 3 · x + 2. Find (f/g) (x).

Solve the system by elimination.(show your work)
PilotLPTM [1.2K]

Answer:

x = 1 , y = 1 , z = 0

Step-by-step explanation by elimination:

Solve the following system:

{-2 x + 2 y + 3 z = 0 | (equation 1)

-2 x - y + z = -3 | (equation 2)

2 x + 3 y + 3 z = 5 | (equation 3)

Subtract equation 1 from equation 2:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x - 3 y - 2 z = -3 | (equation 2)

2 x + 3 y + 3 z = 5 | (equation 3)

Multiply equation 2 by -1:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+3 y + 2 z = 3 | (equation 2)

2 x + 3 y + 3 z = 5 | (equation 3)

Add equation 1 to equation 3:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+3 y + 2 z = 3 | (equation 2)

0 x+5 y + 6 z = 5 | (equation 3)

Swap equation 2 with equation 3:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+5 y + 6 z = 5 | (equation 2)

0 x+3 y + 2 z = 3 | (equation 3)

Subtract 3/5 × (equation 2) from equation 3:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+5 y + 6 z = 5 | (equation 2)

0 x+0 y - (8 z)/5 = 0 | (equation 3)

Multiply equation 3 by 5/8:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+5 y + 6 z = 5 | (equation 2)

0 x+0 y - z = 0 | (equation 3)

Multiply equation 3 by -1:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+5 y + 6 z = 5 | (equation 2)

0 x+0 y+z = 0 | (equation 3)

Subtract 6 × (equation 3) from equation 2:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+5 y+0 z = 5 | (equation 2)

0 x+0 y+z = 0 | (equation 3)

Divide equation 2 by 5:

{-(2 x) + 2 y + 3 z = 0 | (equation 1)

0 x+y+0 z = 1 | (equation 2)

0 x+0 y+z = 0 | (equation 3)

Subtract 2 × (equation 2) from equation 1:

{-(2 x) + 0 y+3 z = -2 | (equation 1)

0 x+y+0 z = 1 | (equation 2)

0 x+0 y+z = 0 | (equation 3)

Subtract 3 × (equation 3) from equation 1:

{-(2 x)+0 y+0 z = -2 | (equation 1)

0 x+y+0 z = 1 | (equation 2)

0 x+0 y+z = 0 | (equation 3)

Divide equation 1 by -2:

{x+0 y+0 z = 1 | (equation 1)

0 x+y+0 z = 1 | (equation 2)

0 x+0 y+z = 0 | (equation 3)

Collect results:

Answer: {x = 1 , y = 1 , z = 0

Please help me answer this question
sergejj [24]

Answer:

72km

Step-by-step explanation:

alex : tomos : annabelle = 2 : 3 : 4

if tomos drove 24km

tomos ratio is 3

so 3 --> 24

<em>1 --> 8 </em>

<u>total ratios --> 2 + 3 + 4 = 9</u>

so total journey is 9 --> 9 * 8 = 72km

Solve for X 2x-20=30
svetlana [45]

Answer:

x = 25

Step-by-step explanation:

2x-20=30

First, isolate the term with x in it by moving everything else to the other side:

2x = 30 + 20

Simplify like terms:

2x = 50

Further isolate the x by dividing by 2 on both sides:

2x/2 = 50/2

The 2 cancels out on the left, leaving:

x = 25
