if f(x)=√2x+3/6x-5, then f(-1/2)=

Answers

Answer 1

answere=-1

this is the answere and the explanation.

If F(x)=2x+3/6x-5, Then F(-1/2)=
Answer 2

By substituting x = -1/2, the expression [tex]\(f(x) = \frac{\sqrt{2x} + 3}{6x - 5}\)[/tex] can be simplified to[tex]f(x) = \(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\).[/tex].

To find [tex]\(f(-\frac{1}{2})\)[/tex], substitute [tex]\(-\frac{1}{2}\)[/tex] into the function f(x):

[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{2 \cdot (-\frac{1}{2}) + 3}}{6 \cdot (-\frac{1}{2}) - 5}\)[/tex]

Now, simplify the expression inside the square root:

[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{-\sqrt{2} + 3}}{-3 - 5}\)\\\(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\)[/tex]

So, [tex]\(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\)[/tex].

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Set Up Equation

"Difference" is subtraction

"y" is y

"8.1" is 8.1

"is" is equal

"20" is 20

y - 8.1 = 20

Step 2: Solve for y

Add 8.1 to both sides:                    y = 28.1

1/4x+3/8 factored by the GCF

Answers

Given:

[tex]\dfrac{1}{4}x+\dfrac{3}{8}[/tex]

To find:

The factor form of given expression by the GCF.

Solution:

First we need to find the GCF of [tex]\dfrac{1}{4}[/tex] and [tex]\dfrac{3}{8}[/tex].

So, make denominators same.

[tex]\dfrac{1}{4}=\dfrac{1\times 2}{4\times 2}=\dfrac{2}{8}[/tex]

Now,

[tex]GCF\left(\dfrac{2}{8},\dfrac{3}{8}\right)=\dfrac{1}{8}[/tex]

[tex]GCF\left(\dfrac{1}{4},\dfrac{3}{8}\right)=\dfrac{1}{8}[/tex]

We have,

[tex]\dfrac{1}{4}x+\dfrac{3}{8}[/tex]

It can be written as

[tex]=\dfrac{2}{8}x+\dfrac{3}{8}[/tex]

Taking out the GCF [tex]\dfrac{1}{8}[/tex], we get

[tex]=\dfrac{1}{8}(2x+3)[/tex]

Therefore, the required factor form is [tex]\dfrac{1}{8}(2x+3)[/tex].

For the function F(x) = }, which of these could be a value of F(x) when xis
close to zero?

Answers

Given:

The graph of the function [tex]f(x)=\dfrac{1}{x}[/tex].

To find:

The value of the function f(x), when x is close to zero.

Solution:

From the given graph it is clear that, f(x) approaches towards infinity and negative infinity as x approaches towards 0.

[tex]f(x)\to \infty[/tex] as [tex]x\to 0^+[/tex]

[tex]f(x)\to -\infty[/tex] as [tex]x\to 0^-[/tex]

In means, the value of must be very large positive value or very large negative if x is close to zero.

From the given options -10,000 is very large negative value.

So, the possible value of f(x) could be -10000 if x is close to 0.

Therefore, the correct option is A.

Mr. Thompson drew a rectangle on the chalkboard with a length to width ratio of 5 to 2. He asked students to draw a rectangle with the same ratio of length to width in their journals. Audrey plans to draw a rectangle with a width of 6 centimeters. What length should Audrey's rectangle have?

Answers

Answer:

15 centimeters

Step-by-step explanation:

Ratio of Mr. Thompson rectangle = length : width

= 5 : 2

Audrey plans to draw a rectangle with a width of 6 centimeters.

Ratio of Audrey rectangle = length : width

= x centimeters : 6 centimeters

Equate the two ratios to find the value of x

5 : 2 = x : 6

Cross product

5 * 6 = 2 * x

30 = 2x

Divide both sides by 2

x = 30 / 2

= 15

x = 15 centimeters

Audrey's rectangle should have a length of 15 centimeters

Find the inverse when f(x)=3x^2-3x-2

Answers

Answer:

The inverse of f(x) is [tex]f^{-1}[/tex](x) =  ± [tex]\sqrt{\frac{x+\frac{11}{4}}{3}}[/tex] + [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

To find the inverse of the quadratic function f(x) = ax² + bx + c, you should put it in the vertex form f(x) = a(x - h)² + k, where

h = [tex]\frac{-b}{2a}[/tex] k is the vlue f at x = h

f(x) = 3x² - 3x - 2

→ Compare it with the 1st form above to find a and b

a = 3 and b = -3

→ Use the rule of h to find it

∵ h = [tex]\frac{-(-3)}{2(3)}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

h =  [tex]\frac{1}{2}[/tex]

→ Substitute x by the value of h in f to find k

∵ k = 3( [tex]\frac{1}{2}[/tex])² - 3( [tex]\frac{1}{2}[/tex]) - 2

k = [tex]-\frac{11}{4}[/tex]

→ Substitute the values of a, h, and k in the vertex form above

∵ f(x) = 3(x -  [tex]\frac{1}{2}[/tex])² + [tex]-\frac{11}{4}[/tex]

f(x) = 3(x -  [tex]\frac{1}{2}[/tex])² - [tex]\frac{11}{4}[/tex]

Now let us find the inverse of f(x)

∵ f(x) = y

y = 3(x -  [tex]\frac{1}{2}[/tex])² - [tex]\frac{11}{4}[/tex]

→ Switch x and y

∵ x = 3(y -  [tex]\frac{1}{2}[/tex])² - [tex]\frac{11}{4}[/tex]

→ Add [tex]\frac{11}{4}[/tex] to both sides

∴ x + [tex]\frac{11}{4}[/tex] = 3(y - [tex]\frac{1}{2}[/tex])²

→ Divide both sides by 3

∵ [tex]\frac{x+\frac{11}{4}}{3}[/tex] = (y - [tex]\frac{1}{2}[/tex])²

→ Take √ for both sides

∴ ± [tex]\sqrt{\frac{x+\frac{11}{4}}{3}}[/tex] = y - [tex]\frac{1}{2}[/tex]

→ Add  [tex]\frac{1}{2}[/tex] to both sides

∴ ± [tex]\sqrt{\frac{x+\frac{11}{4}}{3}}[/tex] + [tex]\frac{1}{2}[/tex] = y

→ Replace y by [tex]f^{-1}[/tex](x)

∴ [tex]f^{-1}[/tex](x) =  ± [tex]\sqrt{\frac{x+\frac{11}{4}}{3}}[/tex] + [tex]\frac{1}{2}[/tex]

The inverse of f(x) is [tex]f^{-1}[/tex](x) =  ± [tex]\sqrt{\frac{x+\frac{11}{4}}{3}}[/tex] + [tex]\frac{1}{2}[/tex]

the length of a rectangle is one unit more than its width. if the area of the rectangle is 56 square units,find the dimensions of the rectangle​

Answers

Given:

The length of a rectangle is one unit more than its width.

Area of rectangle = 56 units

To find:

The dimensions of the rectangle​.

Solution:

Let, width of the rectangle be x.

Then, length of the rectangle = x+1

Area of a rectangle is

[tex]Area=length\times width[/tex]

[tex]56=(x+1)\times x[/tex]

[tex]56=x^2+x[/tex]

[tex]0=x^2+x-56[/tex]

By splitting the middle term, we get

[tex]x^2+8x-7x-56=0[/tex]

[tex]x(x+8)-7(x+8)=0[/tex]

[tex](x-7)(x+8)=0[/tex]

Using zero product property, we get

[tex]x-7=0[/tex] and [tex]x+8=0[/tex]

[tex]x=7[/tex] and [tex]x=-8[/tex]

Width cannot be negative. So, x=7.

Now,

Width = 7 units

Length = 7+1

            = 8 units

Therefore, the length of the rectangle is 8 units and width is 7 units.

One tank is filling at a rate of 5/8 gallon per 7/10 hour. A second tank is filling at a rate of 5/9 gallon per 2/3 hour. Which tank is filling faster?

Answers

Answer:

First tanks

Step-by-step explanation:

Rate for the first tank

One tank is filling at a rate of 5/8 gallon per 7/10 hour.

= 5/8 gallon ÷ 7/10 hour

= 5/8 ×10/7 (gallon/hour)

= 25/28 gallon/hour

= 0.8928571429 gallon /hour

Rate for the second tank

A second tank is filling at a rate of 5/9 gallon per 2/3 hour.

5/9 gallon ÷ 2/3 hour

5/9 × 3/2 (gallon per hour)

= 5/6 (gallon per hour)

= 0.8333333333 gallon/hoir

The tank that is filling faster the first tank at the rate of 0.8928571429 gallon /hour

Answers

Answer:

The slope of the parallel line to the given line is [tex]-\frac{1}{4}[/tex]

The equation of the parallel line to the given line and passes through the given point is y + 4 =  [tex]-\frac{1}{4}[/tex] (x + 2)

The y-intercept of the parallel line to the given line and passes through the given point is  [tex]-\frac{9}{2}[/tex]

Step-by-step explanation:

The rule of the slope of the line that passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]The point-slope form of the linear equation is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the lineThe slope-intercept form of the linear equation is y = m x + b, where m is the slope and b is the y-interceptParallel lines have the same slopes and different y-intercepts

In the given figure

∵ The given line passes through points (2, 6) and (-6, 8)

x1 = 2 and y1 = 6

x2 = -6 and y2 = 8

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{8-6}{-6-2}[/tex] = [tex]\frac{2}{-8}[/tex] = [tex]-\frac{1}{4}[/tex]

The slope of the given line is [tex]-\frac{1}{4}[/tex]  

∵ Parallel lines have the same slopes

The slope of the parallel line to the given line is [tex]-\frac{1}{4}[/tex]

∵ The parallel line passes through the point (-2, -4)

x1 = -2 and y1 = -4

∵ m = [tex]-\frac{1}{4}[/tex]

→ Substitute them in the point-slope form above

∵ y - (-4) = [tex]-\frac{1}{4}[/tex] (x - (-2))

y + 4 =  [tex]-\frac{1}{4}[/tex] (x + 2)

The equation of the parallel line to the given line and passes through

   the given point is y + 4 =  [tex]-\frac{1}{4}[/tex] (x + 2)

∵ m = [tex]-\frac{1}{4}[/tex]

→ Substitute it in the slope-intercept form above

y =  [tex]-\frac{1}{4}[/tex] x + b

→ To find b substitute x by -2 and y by -4 (coordinates the given point)

∵ -4 = [tex]-\frac{1}{4}[/tex](-2) + b

∴ -4 = [tex]\frac{1}{2}[/tex] + b

→ Subtract  [tex]\frac{1}{2}[/tex]  from both sides

[tex]-\frac{9}{2}[/tex] = b

∵ b is the y-intercept

The y-intercept of the parallel line to the given line and passes

   through the given point is  [tex]-\frac{9}{2}[/tex]
