Second option: [tex]3 + 4 x\leq 2 (1 + 2x)[/tex]

Step-by-step explanation:

Let's solve for "x" from each inequality:

[tex]a.\ 6 (x + 2)>x-3\\\\6x+12>x-3\\\\6x-x>-3-12\\\\5x>-15\\\\x>\frac{-15}{5}\\\\x>-3[/tex]

[tex]b.\ 3 + 4 x\leq 2 (1 + 2x)\\\\3+4x\leq 2+4x\\\\3-2\leq 4x-4x\\\\1\leq 0\  (FALSE.\ IT\ HAS\ NO\ SOLUTION)[/tex]

[tex]c.\ -2 (x + 6)<x-20\\\\-2x-12<x-20\\\\-12+20<x+2x\\\\8<3x\\\\x>\frac{8}{3}[/tex]

[tex]d.\ x-9<3(x-3)\\\\x-9<3x-9\\\\x-3x<-9+9\\\\-2x<0\\\\x>0[/tex]

The inequality that has no solution is: 3 + 4x ≤ 2(1 + 2x).

The correct option is 2nd.

Given are inequalities, we need to check which of them has no solution.

Let's solve each inequality to determine if it has a solution:

1) 6(x + 2) > x - 3

First, distribute the 6:

6x + 12 > x - 3

Now, let's isolate the variable x on one side:

6x - x > -3 - 12

5x > -15

Finally, divide by 5 to solve for x:

x > -3

This inequality does have a solution, and x can take any value greater than -3.

2) 3 + 4x ≤ 2(1 + 2x)

First, distribute the 2 on the right side:

3 + 4x ≤ 2 + 4x

Now, subtract 4x from both sides:

3 ≤ 2

This is not true, and there is no value of x that satisfies this inequality.

So, this inequality has no solution.

3) -2(x + 6) < x - 20

First, distribute the -2:

-2x - 12 < x - 20

Now, let's isolate the variable x on one side:

-2x - x < -20 + 12

-3x < -8

Finally, divide by -3 to solve for x (note the sign change when dividing by a negative number):

x > 8/3 or x > 2.67

This inequality has a solution, and x can take any value greater than 2.67.

4) x - 9 < 3(x - 3)

First, distribute the 3 on the right side:

x - 9 < 3x - 9

Now, move the variables to one side:

x - 3x < 9 - 9

-2x < 0

Finally, divide by -2 to solve for x (note the sign change when dividing by a negative number):

x > 0

This inequality has a solution, and x can take any value greater than 0.

Hence, the inequality that has no solution is: 3 + 4x ≤ 2(1 + 2x).

The correct option is 2nd.

Answer:

$486

Step-by-step explanation:

First you find the area of the window. The area of a square is equal to h×w, so we take 9×9 which equals 81. Since it costs $6 per square foot, we now take 81×6, which gives us an answer of $486.

The glass to replace the window will cost $486 to Linda.

The Area of a figure is the space inside its 2D perimeter.

To determine the area of a square we just square the length of its side.

Area of a square = (side)²

We are said that the window is in the shape of a square, with 9 feet as its side's length.

∴ Area of the window = 9² square feet = 81 square feet.

Cost of 1 square foot of glass = $6/square foot

∴ Cost of the glass for window = Area of the window * rate of glass

= $81*6 = $486.

∴ The glass to replace the window will cost $486 to Linda.

No. The differences between two elements should be same. For example 4-7-10-13 is a arithmetic sequence.

Step-by-step explanation:

Answer: OPTION C.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope of the line and "b" is the y-intercept.

In order to verify which fucntion is not linear, you can solve for "y" from each function. Then:

[tex]A.\ y+1= x\\\\y=x-1[/tex]

This is a Linear function.

[tex]B.\ x=2y-3\\\\x+3=2y\\\\y=\frac{1}{2}x+\frac{3}{2}[/tex]

This is a Linear function.

[tex]C.\ xy=2\\\\y=\frac{2}{x}[/tex]

This is NOT a Linear function.

[tex]D.\ x+1=\frac{3}{4}y\\\\4x+4=3y\\\\y=\frac{4}{3}x+\frac{4}{3}[/tex]

This is a Linear function.

Final answer:

Option C) xy = 2 does not represent a linear function because it cannot be rewritten in the form y = mx + b, which is characteristic of linear equations. Instead, it represents a hyperbola.

Explanation:

The question asks: "Which does NOT represent a linear function?" with the options being A) y+1= x, B) x=2y-3, C) xy=2, and D) x+1=3/4y. To determine which equation does not represent a linear function, we must recall that linear functions can always be written in the form y = mx + b, where m is the slope and b is the y-intercept.

A) y+1 = x can be rewritten as y = x - 1, which is linear.

B) x = 2y - 3 can be rewritten as y = 1/2x + 3/2, which is linear.

C) xy = 2 cannot be rewritten in the form y = mx + b because it involves both x and y being multiplied together, which is characteristic of a hyperbola, not a linear equation.

D) x + 1 = 3/4y can be rearranged to y = 4/3x + 4/3, which is linear.

Therefore, the equation that does NOT represent a linear function is C) xy = 2.

The mileages for which company A charge less than company B when , y [tex]>[/tex] 50 .

Step-by-step explanation:

Given as :

The two truck companies have following prices

Company A

The initial fee = i = $110

And unlimited mileage

Company B

The initial fee = I = $65

Additional charge = $0.90 per mile driven

Let it driven x mile

Let The mileages for which company A charge less than company B = y

Now, According to question

Charges of company A = charges of company B

i.e i = I + 0.90 × x

Or, $110 = $65 + 0.90 × x

Or, $110 - $65 = 0.90 × x

Or, $45 = 0.90 × x

∴    x = [tex]\dfrac{45}{0.90}[/tex]

i.e  x = 50

i.e  Company B driven x = 50 miles

So, The mileages for which company A charge less than company B = y

Hence, The mileages for which company A charge less than company B when , y [tex]>[/tex] 50 . Answer

The equation of the line perpendicular to line AB, which is a vertical line with an undefined slope, and passing through the point (2, 4) is y = 4.

Determine the equation of the perpendicular line:

Find the slope of line AB:

Since both points A and B have the same x-coordinate (-6), the line AB is a vertical line.

Vertical lines have an undefined slope.

Determine the slope of the perpendicular line:

The slope of a line perpendicular to a vertical line is 0. This means the perpendicular line will be a horizontal line.

Use the point-slope form to find the equation of the perpendicular line:

The point-slope form of a linear equation is: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

We know the slope (m = 0) and we have a point on the line (2, 4).

Plugging these values into the point-slope form, we get: y - 4 = 0(x - 2)

Simplify the equation:

Since the slope is 0, the term 0(x - 2) becomes 0.

Therefore, the equation simplifies to: y - 4 = 0

Add 4 to both sides to isolate y:

y = 4

Therefore, the equation of the line perpendicular to line AB and passing through the point (2, 4) is y = 4.

If bills new porch is rectangular with an area of 50 square feet if the length of the porch is two times the width. Then 30 feet is the perimeter of the porch

The area of Rectangle is length times of width.

Given,

bills new porch is rectangular with an area of 50 square feet

Area=50  square feet

Length of the porch is two times the width

Length=2Width

Area=Length×Width

x and y show what points are on the line. We know (4, 12). x= 4 and y = 12

b is the y-intercept, which b = -2.

m is the slope.

To write the equation, you need the slope and y-intercept. Find the slope by putting x, y and b into the formula.

y = mx + b

Let X = the number of weeks.

Jeanette will pass 3 per week, so 3x, and she already passed 8, so Jeanette would be 3x +8

Paul would be 4x + 3

Set them to equal to solve for x ( the number of weeks.)

3x +8 = 4x +3

Subtract 3x from both sides:

8 = x +3

Subtract 3 from both sides:

X = 5

So it will take 5 weeks to be the same.

Replace X with 5 to find the number of scales.

3x + 8 = 3(5) + 8 = 15 +8 = 23

⇒ (15x-1) + (13x+1) + 3×\sqrt[3]{15x-1}× \sqrt[3]{13x+1} (\sqrt[3]{15x-1} +  \sqrt[3]{13x+1}) = 64 x.

(since (a+b)³ = a³ + b³ + 3ab(a+b) ).

⇒ 28x + 3×\sqrt[3]{15x-1}× \sqrt[3]{13x+1} (\sqrt[3]{15x-1} +  \sqrt[3]{13x+1})  = 64x.        

(since from (1), \sqrt[3]{15x-1} + \sqrt[3]{13x+1} = 4\sqrt[3]{x} )

⇒ 12×\sqrt[3]{15x-1}× \sqrt[3]{13x+1} (\sqrt[3]{15x-1}×\sqrt[3]{x}= 36x.

⇒ 3x = [tex]\sqrt[3]{(15x-1)(13x+1)(x)}[/tex] .

Now, once again cubing on both sides, we get

(3x)³ = ([tex]\sqrt[3]{(15x-1)(13x+1)(x)}[/tex])³.

⇒ 27x³ = (15x-1)(13x+1)(x).

⇒ 27x³ = 195x³ + 2x² - x

⇒ 168x³ + 2x² - x = 0

⇒ x(168x² + 2x -1) = 0

⇒ by, solving the equation we get ,

x = 0 ; x = \frac{1}{14}   ; x = \frac{-1}{12}

therefore, solution is x= 0 , x = \frac{1}{14}   ,  x = \frac{-1}{12}

Answer:

First fund: $4000

second account: $2000

Step-by-step explanation:

invest x for first fund (A) and y for second fund (B)

interest for A: x * 0.05

interest for B: y * 0.09

0.05 x + 0.09 y = 380 ....(1)

x + y = 6000 ..... (2)

y = 6000 - x   ....substitute y in (1)

0.05 x + 0.09 (6000 - x) = 380

0.05x + 540 - 0.09x = 380

0.04 x = 160

x = 4000

y = 6000 -4000 = 2000

check: 4000 x 0.05 + 2000 x 0.09 = 200 + 180 = 380
