Answer:

[tex] - 3 \times \frac{3}{7 } [/tex]

Answer:

19

Step-by-step explanation:

Alr so.

what you have to do is first convert yourpercentage into a decimal and to do that you need to move the decimal 2 places to the left like so-

61.3% --->  .613

Next you need to multiply 31 x .613 which gives you 19.003

or 19 Passed :)

The number of points at the end of second round is :

and if he loses all the 5 five points in the third round then the number of point he is left with is :

Answer:

(13,-6)

Step-by-step explanation:

If you are at (-3,5) and you translate T to give you (6,-8), that means you translated (9,-13) because you moved right 9 units in the positive x direction and down 13 units in the negative y direction.

Apply this translation T to (4,7) and you get (13,-6).

Answer:

(13,  -6)

Step-by-step explanation:

Firstly, we need to find the translation. This can be achieved by calculating the amount the x and y coordinate shifts. Simply use the following equation:

[tex](x2 - x1, y2 - y1)[/tex]

Where x1 and y1 are the coordinates of the first set and x2 and y2 are the second. Plug the variables in:

[tex](6 - (-3), -8 - 5)\\(9, -13)[/tex]

So the x coordinate is shifted 9 positively and the y coordinate is shifted 13 negatively.

To calculate the new translation of the new point, add the translation onto the given coordinates:

[tex]( 4 + 9, 7 + (-13) )\\(13, -6)[/tex]

So the new point is (13,  -6).

Hope this helps!

Y-intercept=(0, 2)

X-intercepts=(-4,0) & (-2,0)

Step-by-step explanation:

X and y- intercepts are determined when they pass through either the x or y axis. If the line passes through the x axis it is the x-intercept and vice versa for y.

Answer: n = 2 ....... (2, -4)

Step-by-step explanation:

To find n, one must write the equation for the points given, which are (-2, 4) and (-4, 8). Remember, the standard linear equation is y = mx + b, where m is the slope of the line.

To find the slope, refer back to (y2-y1)/(x2-x1), or in this case, (8-4)/(-4+2), which gives us -2

With our slope of -2, we can write the equation as y = -2x+b. Now, we need to find b (the y-intercept) by plugging in a point as (x,y)

Let's use (-4,8) point and plug it into our linear equation: y = -2x+b

to get 8=(-2)(-4) +b

8=8+b

0=b (which means our y-intercept is 0)

Now, our official linear equation is y=-2x

The problem gives us (n, -4) where -4 y, so we plug in -4 as y in the equation to get:

-4=-2x

-4/-2=x

2 = x

And there we go :) I hope this helps!

Answer:

The value of n =  2.

Step-by-step explanation:

Given the following points passing through a line, (-2, 4), (-4, 8), and (n , -4) wherein we must find the value of n:

It helps to determine the equation of the line, using the slope-intercept form: y = mx + b, where:

In order to solve for the slope of the line, use the following slope formula:

[tex]\displaystyle\mathsf{m =\:\frac{y_2 - y_1}{x_2 - x_1}}[/tex]

Let (x₁, y₁) = (-2, 4)

     (x₂, y₂) = (-4, 8)

Substitute these values into the slope formula.

[tex]\displaystyle\mathsf{m =\:\frac{y_2 - y_1}{x_2 - x_1}}[/tex]

[tex]\displaystyle\mathsf{m =\:\frac{8 - 4}{-4 -(-2)}\:=\:\frac{4}{-4+2}\:=\Frac{4}{-2}\:=\:-2}[/tex]

Hence, the slope of the line is: m = -2.

Next, we must solve for the y-intercept.  Since it is the point where the graph crosses the y-axis, set x = 0 and solve for the value of y.  

Use the slope, m = -2, and one of the given points, (-2, 4), and substitute these values into the slope-intercept form to solve for the value of the y-intercept, b:

y = mx + b

4 = -2(-2) + b

4 = 4 + b

Subtract 4 from both sides:

4 - 4 = 4 - 4 + b

0  = b

The y-intercept is: b = 0.

Therefore, the equation of the line in slope-intercept form is:

y = -2x + 0 or y = -2x.

In order to determine the value of n, substitute its corresponding y-coordinate, -4, and substitute into the equation in the previous step:

Set y = -4:

y = -2x

-4 = -2x

Divide both sides by -2 to solve for x:

[tex]\displaystyle\mathsf{\frac{-4}{-2}\:=\:\frac{-2x}{-2}}[/tex]

x = 2

Therefore, the value of n = 2.

Answer:

The slope is zero

Step-by-step explanation:

y = -4 is a horizontal line

Horizontal lines have a slope of zero

Hello there! The line y=-4 is a horizontal line and the slope of horizontal lines is 0.

Why? Because we calculate the slope using the formula Rise/Run. The rise is 0 (how many units we go up) so no matter what the run is, if we divide 0 by any number, we will get 0 100%.

Similar polygons will have proportional side lengths. So, let's check each of these using proportions and cross-multiplying.

Proportion: left rectangle length / left rectangle width = right rectangle length / right rectangle width

Top Left Rectangles: Proportional

6.4 / 5.6 = 1.6 / 1.4

8.96 = 8.96

Top Right Rectangles: Not Proportional

10.2 / 6.2 = 5.2 / 1.2

32.24 does not equal 12.24

Bottom Left Rectangles: Proportional

39 / 27 = 13 / 9

351 = 351

Bottom Right Rectangles: Not Proportional

Answer:

[tex]\frac{T+z-2x}{3}[/tex]=y

Step-by-step explanation:

On solving for y we get -

[tex]$y=\frac{T-2x+z}{3}[/tex]

We have the following expression -

T = 2x + 3y - z

We have to solve for ' y '.

On solving, we get -

Sin([tex]2n\pi x[/tex]) = 0.785

Sin([tex]2n\pi x[/tex]) = Sin ([tex]\frac{\pi }{4}[/tex])

2n[tex]\pi[/tex]x = [tex]\frac{\pi }{4}[/tex]

x = [tex]\frac{1}{8n}[/tex]

According to the question, we have -

T = 2x + 3y - z

T - 2x + z = 3y

[tex]$y=\frac{T-2x+z}{3}[/tex]

Hence, on solving for y we get -

[tex]$y=\frac{T-2x+z}{3}[/tex]
