What is the solution for the following system of equations? x +2y=6

john because 1 yard is equal to 3 ft, 4x3=12 ft

Final answer:

Jane has more fabric than John with a difference of 24 inches.

Explanation:

To compare the amount of fabric John and Jane have, we need to convert their measurements into the same unit. Since John has 4 yards of fabric and Jane has 120 inches, we need to convert yards to inches or inches to yards.
To convert yards to inches, we know that 1 yard is equal to 36 inches. So, multiplying 4 yards by 36 inches per yard, we get 144 inches of fabric for John.
Comparing the two measurements, we can see that Jane has more fabric with 120 inches compared to John's 144 inches. The difference is 144 inches - 120 inches = 24 inches. Therefore, Jane has 24 inches more fabric than John.

Step-by-step explanation:

Existing walkway

 l = 10 ft

w = 4 ft

A₁ = lw = 10 ft × 4 ft = 40 ft²

New walkway

Expanding a measurement by 25 % means that you multiply it by a factor of 1.25.

New length = 10 × 1.25 = 12.5 ft

New width =    4 × 1.25 =   5    ft

A₂ = lw = 12.5 ft × 5 ft = 62.5 ft²

Increase in area

A₂ - A₁ = 62.5 – 40 = 22.5 ft²

( 19/3 , 2 )

Step-by-step explanation:

Given in the question,

point D(7,1)

x1 = 7

y1 = 1

point F(5,4)

x2 = 5

y2 = 4

Location of point E which is 1/3 of the way from D to F

which means ratio of point E from D to F is 1 : 2

1 : 2

xk = [tex]x1 + \frac{a}{a+b}(x2-x1)[/tex]

yk = [tex]y1 + \frac{a}{a+b}(y2-y1)[/tex]

Plug values in the equation

xk = 7 + (1)/(1+2) (5-7)

xk = 19/3

yk = 1 + (1)/(1+2)(4-1)

yk = 2

Answer:

This is a Pythagorean triple.

Step-by-step explanation:

In order to find this, use the Pythagorean Theorem to and see if it gives a true statement.

a^2 + b^2 = c^2

15^2 + 20^2 = 25^2

225 + 400 = 625

625 = 625

Since this is a true statement, we know that this is a Pythagorean Triple.

Answer:

f(x) = x² + 9x - 22

Step-by-step explanation:

Given that x = 2 and x = - 11 are zeros, then

(x - 2) and (x + 11) are factors

and f(x) equals the product of the factors

f(x) = (x - 2)(x + 11) ← expand factors

f(x) = x² + 9x - 22 ← is a possible function

The quadratic function [tex]\( f \)[/tex] with zeros at [tex]\( x = 2 \) and \( x = -11 \)[/tex] can be written in factored form as: [tex]\[ f(x) = x^2 + 9x - 22 \][/tex]

The standard form of a quadratic function is:

[tex]\[ f(x) = ax^2 + bx + c \][/tex]

To convert the factored form to standard form, we expand the factors:

[tex]\[ f(x) = a(x^2 + 11x - 2x - 22) \] \[ f(x) = a(x^2 + 9x - 22) \] \[ f(x) = ax^2 + 9ax - 22a \][/tex]

[tex]\[ b = 9a \] \[ c = -22a \][/tex]

So, the quadratic function with zeros at [tex]\( x = 2 \) and \( x = -11 \) is:[/tex]

[tex]\[ f(x) = ax^2 + 9ax - 22a \] \[ f(x) = x^2 + 9x - 22 \][/tex]

Area of 81 sq in: 40.2

Perimeter of 36 in : 9

Step-by-step explanation:

Hope I'm right! :)

Answer:

9 inches

Step-by-step explanation:

A square has an area of 81 in^2

A = s^2

81 = s^2

Take the square root of each side

sqrt(81) = sqrt(s^2)

9 = s

The side length is 9 inches

A square has a perimeter of 36 in

P = 4s

36 = 4s

Divide each side by 4

36/4 = 4s/4

9 = s

Each side is 9 inches

Answer:

(1/3)³c = 5

(1/27)c = 5

c = 5 × 27 = 135 cubes

The Main Answer is 135. It takes [tex]135[/tex] of the [tex]1/3[/tex] unit cubes to fill the rectangular prism.

To find out how many [tex]1/3[/tex] unit cubes it takes to fill the rectangular prism with a volume of [tex]5[/tex] cubic units, we need to divide the volume of the prism by the volume of each individual cube.

The volume of the rectangular prism is given as [tex]5[/tex] cubic units. Since the prism is a rectangular shape, we can calculate its volume using the formula:

[tex]Volume of prism=length*width*height[/tex]

Given that the side length of each cube is [tex]1/3[/tex] unit, the volume of each cube is:

[tex]Volume of cube=(side length)^{3} =(1/3)^{3}=1/27 cubic[/tex]

Now, to find out how many cubes are needed to fill the prism, we divide the volume of the prism by the volume of each cube:

[tex]Number of cubes=Volume of prism/Volume of cube \\Number of cubes=5/(1/27)\\Number of cubes=5*27\\Number of cubes=135[/tex]

So, it takes [tex]135[/tex] of the [tex]1/3[/tex] unit cubes to fill the rectangular prism.

Answer:

Exact volume = 294π in³

Approximate volume = 923.6 in³

Explanation:

The volume of a cylinder can be calculated using the following rule:

volume = πr²h

where r is the radius and h is the height of the cylinder

In the given cylinder:

radius = r = 7 in

height = h = 6 in

Substitute with the givens in the formula to get the volume:

Volume of cylinder = πr²h = π(7)²(6) = 294π in³ ≈ 923.6 in³ to the nearest tenth

Hope this helps :)

For this case we have that the equation of a line in the slope form intersection is given by:[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut point with the y axis.

In the green graph we observe that[tex]b = 2[/tex], then its equation is [tex]y = 5x + 2[/tex]

We have the slope of the red line substituting two points:

[tex](0,2)\\(-1,0)[/tex]

[tex]m = \frac {0-2} {- 1-0} = 2[/tex]

Thus, the red line has equation[tex]y = 2x + 3[/tex]

Finally, the blue line is [tex]y = 3x + 3[/tex]

Answer:

Green line, y = 5x + 2

Red line, y = 2x + 3

Blue line, y = 3x + 3

Answer:

1 - green line: y = 5x + 2

2 - red line: y = 3x + 3

3 - blue line: y = 2x + 3

Step-by-step explanation:

1 - green line

The graph with the green line is the easiest to match with an equation.

If you look at the graph, you see that when x = 0, the y-value is 2.

There's only one of the given equations that y = 2 when x = 0, the first one.

y = 5x + 2

y = 5 (0) + 2 = 0 + 2 = 2

It's easy to spot, because in the format y = mx + b, the b is the value of Y when x = 0, as we just demonstrated.

2 - Red line

In this case, when x = 0, y = 3.  And there are 2 equations for which it's true... which is normal because the blue line (in next graph) also passes by this point.

Then to know which equation goes with the red line graph, we have two choices...

A. determine the slope (rate of change) of the red line and see if it matches one of the equations.

B. See what value of X yields a value of 0 for Y and see where it would land on the X-axis.

The second method is faster.  If you see on the graph, when y = 0, x = -1

If we take the 2nd equation (y = 3x + 3) and we set the value of y to 0, we have:

0 = 3x + 3

-3 = 3x

x = -1

Which is exactly what we wanted to find.

So, the red line is y = 3x + 3

3. blue line

Well, there's only one answer left (y = 2x + 3), so it's easy... but let's make sure by finding the slope (method A listed for the red line above), in case your teacher would be playing tricks on you.

The slope of a line is the variation of y-value (Δy) divided by the variation of x-value (Δx).

If we take the two points where the blue line crosses the axis, we have (-1.5, 0) and (0,3).

Now, let's calculate the slope:

S = (0 - 3) / (-1.5 - 0) = -3 / -1.5 = 2

And 2 is the slope of the equation y = 2x + 3

So, we're good.

Step-by-step explanation:

Since this is a right triangle, we can use the tan function

tan B = opposite side/ adjacent side

tan B = 4/3

Take the inverse tan of each side

tan ^-1 (tan B) = tan^-1 (4/3)

B = 53.13010235

To the nearest hundredth

B = 53.13

To find the cost of the magazine, represent the cost of each book as 'x'. Use the given information to set up an equation and solve for 'x'.

To find the cost of the magazine, let's represent the cost of each book as 'x'. Since the magazine costs twice as much as each book, we can represent the cost of the magazine as '2x'.

According to the problem, Ryan bought 3 books and a magazine and paid $30. We can write this information as an equation:

3x + 2x = 30

Combining like terms, we get:

5x = 30

To isolate the variable 'x', we divide both sides of the equation by 5:

x = 6

Therefore, each book costs $6 and the magazine costs twice as much, which is $12.

The cost of the magazine is $10.

Let's denote the cost of each book as B and the cost of the magazine as M. According to the given information:

Now, we also know that the magazine costs twice as much as each book, so M = 2B. Substitute M with 2B in the equations:

Now that we know the cost of each book (B = 6), we can find the cost of the magazine (M) using M = 2B:

M = 2 times 5 = 10

So, the cost of the magazine is $10.
