What is 1/2(x+14) because i am having trouble solving it and no calculator has been able to help me also.

Hi there!

»»————-　★　————-««

I believe your answer is:

$\frac{1}{2}x+7$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Simplifying the equation...}}\\\\\frac{1}{2}(x+14)\\------------\\\rightarrow \frac{1}{2}*x = \frac{1}{2}x\\\\\rightarrow\frac{1}{2}*14=7\\\\\rightarrow \frac{1}{2}(x+14)= \boxed{\frac{1}{2}x+7}$

E graph shows the altitude of a helicopter over time.

DaniilM [7]

Let

x-------> the time

y-------> the altitude of a helicopter

Step 1

<u>Find the slope of the line</u>

we know that

the slope m of the line between two points is equal to

$m=\frac{(y2-y1)}{(x2-x1)}$

we have

$(x1,y1)=(0,10,000)\\(x2,y2)=(15,4,000)$

substitute in the formula

$m=\frac{(4,000-10,000)}{(15-0)}$

$m=\frac{(-6,000)}{(15)}$

$m=-400\frac{feet}{minute}$

therefore

<u>the answer is the option </u>

The slope is $-400$ . This means that the helicopter descends $400$ ft each minute.
