Answer:</h2>
First of all let's write the slope-intercept form of the equation of a line, which is:
![y=mx+b \\ \\ Where: \\ \\ m: \ slope \\ \\ b: \ y-intercept](https://tex.z-dn.net/?f=y%3Dmx%2Bb%20%5C%5C%20%5C%5C%20Where%3A%20%5C%5C%20%5C%5C%20m%3A%20%5C%20slope%20%5C%5C%20%5C%5C%20b%3A%20%5C%20y-intercept)
So we just need to find
to solve this problem.
Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:
![m=-12](https://tex.z-dn.net/?f=m%3D-12)
Negative slope because Amir is descending. So:
![y=-12x+b](https://tex.z-dn.net/?f=y%3D-12x%2Bb)
To find
, we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point
. Therefore, substituting this point into our equation:
Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:
![\boxed{y=-12x+360}](https://tex.z-dn.net/?f=%5Cboxed%7By%3D-12x%2B360%7D)
Whose graph is shown bellow.
Answer:
50
Step-by-step explanation:
MHJ and LHK are vertical angles, which means they are equal
2x-20 = x+15
Subtract x from each side
2x-20-x = x+15-x
x-20 = 15
Add 20 to each side
x-20+20 = 15+20
x = 35
We want to find MHJ
MHJ =2x-20
=2(35) -20
= 70 -20
= 50
