What is the excluded value? 2x/1-2x

Mathematics
1 answer:
Rashid [163]3 years ago
7 0

Answer:

x = \frac{1}{2}

Step-by-step explanation:

Excluded values are values that will make the denominator of a fraction equal to 0

For the given fraction \frac{2x}{1-2x}

The denominator = 1 - 2x

To find the excluded value: 1 - 2x = 0

2x = 1

x = 1/2

So, the excluded value of \frac{2x}{1-2x} is x = \frac{1}{2}

In the year 2005, there were 100 rabbits in a particular region. Since then, the population has increased by 3.4% per year. Writ
Andreas93 [3]

Answer:

Step-by-step explanation:

Your answer

Ok, lets do it systematically.

2005– 100 rabbits

3.4 % per year increasement.

So every year it increase 0.034 *100 = 3.4 per year

Total 2025-2005= 20 years

So expression is : 0.034*100*year(20)

Answer is : 3.4*20 = 68. So, in 2025, total rabbits will be 168

1. is he equation true , false, or open
RideAnS [48]

Question 1:

For this case we have the following equation:

 5x ^ 2 = 6x + 11

We observe that the equation is a polynomial of the second degree.

Therefore, the equation has two possible solutions.

The variable of the equation for this case is x.

In this case, we have an open equation because we have a variable.

Rewriting the equation we have:

5x ^ 2 - 6x - 11 = 0

Answer:

open, there is a variable.


Question 2:

For this case we have the following equation:

 2-8x = -6

From here, we must clear the value of x.

For this, we follow the following steps:

1) Pass the value of 8x adding:

2 = -6 + 8x

2) Pass the value of 6 adding:

2 + 6 = 8x

3) Add the values ​​on the same side of equality:

 8x = 8

4) Pass the 8 to divide:

x = \frac{8}{8} = 1

Answer:

The value of x is given by:

x = 1


Question 3:

For this case we have the following equation:

 y = x-4

The ordered pair solution is the one that satisfies both sides of the equation.

For the point (6, 2) we have:

x = 6  y = 2

Substituting values ​​we have:

2 = 6-4  2 = 2

We observe that both sides of the equation are equal.

Therefore, the ordered pair solution is (6, 2)

Answer:

An ordered pair that is a solution of the equation y = x-4 is:

(6, 2)

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?
Llana [10]
F(x) = -x² + 4
g(x) = 6x

(g - f)(3) = 6(3) - (-(3)² + 4)
(g - f)(3) = 18 - (-9 + 4)
(g - f)(3) = 18 - (-5)
(g - f)(3) = 18 + 5
(g - f)(3) = 23

Match the information on the left with the appropriate equation on the right.
solmaris [256]

Answer:

Step-by-step explanation:

1). Equation of a line which has slope 'm' and y-intercept as 'b' is,

y = mx + b

If slope 'm' = 1 and y-intercept 'b' = -3

Equation of the line will be,

y = x - 3

x - y = 3

2). Equation of a line having slope 'm' and passing through a point (x', y') is,

y - y' = m(x - x')

If the slope 'm' = 1 and point is (-1, 2),

The the equation of the line will be,

y - 2 = 1(x + 1)

y = x + 1 + 2

y = x + 3

x - y = -3

3). Equation of a line passing through two points (x_1, y_1) and (x_2,y_2) will be,

y-y_1=\frac{(y_2-y_1)}{(x_2-x_1)}(x-x_1)

If this line passes through (-2, 3) and (-3, 4),

y-3=\frac{(4-3)}{(-3+2)}(x+2)

y - 3 = -1(x + 2)

y = -x - 2 + 3

y = -x + 1

x + y = 1
