Given that "Jane wrote all the natural numbers from 5 to k. Including 1 and k"

So Jane wrote k numbers.

lets take an example

if k = 10 , then natural numbers between 1 and 10 are 10 numbers that are 1 , 2 , 3 ,4 ,5 ,6 , 7 , 8 ,9 and 10.

Hence she write k numbers.

The endpoints of AB¯¯¯¯¯¯¯¯ are 8 and 16. Find the coordinate of the point P that partitions the segment in the ratio 3 : 1.

Marina CMI [18]

Answer:

The coordinates of the point P is 14.

Step-by-step explanation:

Let point A is at 8 and B is at 16.

P is the point where the line segment in the ratio 3 : 1.

This is also where P is $\frac{3}{4}$ rds the distance from A to B

The total distance is |16 - 8| = 8

The distance between point AB is 8 units.

$\frac{3}{4}$ of 8 is 6.

So, the point P is 6 units from A .

8 + 6 = 14

P is at 14

Hence, the coordinates of the point P is 14.

This also works if you go 1/3 from B.

-8 is 4 from -4 which is 1/3 of 12.

Look at this expression.

g100num [7]

Multiply x and 3

Multiply x and 1

The x just gets copied along.

The answer is x

3*x evaluates to 3x

Because of the minus sign

3x becomes - 3x

The answer is -3x

Multiply y and 2

Multiply y and 1

The y just gets copied along.

The answer is y

2*y evaluates to 2y

-3*x-2*y evaluates to -3x-2y

The answer is -3x-2y-2

-3*x-2*y-2 evaluates to -3x-2y-2

so the first one is right

5x=15 y 2x=6 Son ecuaciones equivalentes? PORFAVOR AYÚDENME ES EMERGENCIA

mihalych1998 [28]

Si, los dos son iguales

Cuando haces 5x=15, la división dice que x = 3. Para 2x=6 puedes usar el resultado de x=3 de la problema de antes, y cuando te usas esto va a ver que 2 de x cuando x=3 es igual a 6, y por eso 5x=15 y 2x=6 son equivalentes.

The following table shows the distance from school as a function time

kykrilka [37]

Answer:

27,0 the distance away from the school

Step-by-step explanation:

Apply the formula for equation of a straight line;

y=mx+c where c is the y intercept , and m is the gradient

From the graph, the slope is negative where speed decreases with increase in time

Find the gradient by applying the formula;

$m=\frac{y_2-y_1}{x_2-x_1}$

Taking y₁=24, y₂=20, x₁=9, x₂=12

Then;

$m=\frac{20-24}{12-9} =\frac{-4}{3}$

write the equation of the function as ;

y=mx+c, c=36( the y-intercept when x=0) hence the equation is;

$y=mx+c\\\\y=\frac{-4}{3}x+36$

To get x-intercept, substitute value of y with 0

$y=mx+c\\\\\\y=-\frac{4}{3} +36\\\\\\0=-\frac{4}{3} x+36\\\\\frac{4}{3}x =36\\\\\\4x=36*3\\\\\\x=108/4=27$

This means that the x-intercept is 27 ,and this means you will require 27 minutes to cover the whole distance to the school.
