The last choice: Running up a hill, then walking up a hill, turning around and running down the hill, then walking down the hill

Situation: D because running up a hill first takes less time, which you can see in the graph. Then, walking up a hill takes more time and you are going upward, which is expressed in the graph. Next, you run down the hill, which takes less time than walking which is on the graph. Finally, you walk the remainder of the hill downwards, which takes more time and is shown in the graph. Hope this helps!

What is the equation of the line

konstantin123 [22]

Hello there!

The answer is B. $\frac{2}{7}$
-----------------------------------------------------------------------------------------------------

Explanation and Work:

We first must identify if the line goes through the origin or not.

The origin is (0, 0)

The line does go through the origin. This means that there is no y-intercept

The specific equation we would you use would be:

y = kx

K is the constant

We find this by finding the slope.

Slope is found by:

$\frac{y2 - y1}{x2 - x1}$

y2 = 2

y1 = 0

x2 = 7

x1 = 0

Now, let's plug in these numbers.

$\frac{2-0}{7-0} = \frac{2}{7}$

So, now let's plug he slope into our formula.

y = $\frac{2}{7} x$

So, our answer would be B.

I hope I helped!

Find three solutions of the equation y=9x-4?

Bas_tet [7]

<span>answer
A) (-5,-49),(-2,-22),(3,23)

</span>when x = - 5 ; y=9x-4 = 9(-5) -4 = -49
when x = - 2 ; y=9x-4 = 9(-2) -4 = -22
when x = 3 ; y=9x-4 = 9(3) -4 = 23

a pyramid has a regular hexagonal base with side length of 4 and a slant height of 6. what is the total area of the pyramid

Stels [109]

So hmm notice the picture below

the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges

now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then
$\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}\cdot n\cdot s^2\cdot cot\left( \frac{180}{n} \right)\qquad 
\begin{cases}
n=\textit{number of sides}\\
s=\textit{length of a side}\\
\frac{180}{n}=\textit{angle in degrees}\\
----------\\
n=6\\
s=4
\end{cases}\\\\\\ A=\cfrac{1}{4}\cdot 6\cdot 4^2\cdot cot\left( \frac{180}{6} \right)$

now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both

PLEASE PLEASE PLEASE HELP I WILL GIVE BRAINLIEST

Answer:

y > 6x -100

Step-by-step explanation:

the slope intercept equation of the line is

y=mx+b

m is the slope = (y2-y1) / (x2-x1) so between the y-intercept (0,-100) and the given point (25, 50) we have m= -100-50/0-25 = -150/-25 = 6

y= 6x -100

now we have to figure the inequqlity part so take point (0, 0) that belongs to the solution and substitute in the equation

0 = 6*0 -100

0 = -100 for the equation to be true we have to make it 0 > -100, we also need to make it NOT greater or equal then because the line is doted not solid so the inequality is

y > 6x -100
