Answer with explanation:
If we draw a Vertical number line, Where Sea level Represents=0,
Point on number line where Rory is standing = +300 feet
Equation of average change in elevation over time is given by equation:
e = 300 - 10 t
So, when t=0, e=300
and, when e=0 , gives ,
10 t= 300
→→Dividing both sides by 10
t =30
→Average change
![=\frac{e_{2}-e_{1}}{t_{2}-t_{1}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Be_%7B2%7D-e_%7B1%7D%7D%7Bt_%7B2%7D-t_%7B1%7D%7D)
→Rate of change
![=\frac{300-0}{0-10}=-30{\frac{feet}{minute}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B300-0%7D%7B0-10%7D%3D-30%7B%5Cfrac%7Bfeet%7D%7Bminute%7D%7D)
Viable points →
e (feet) 300 0
t (minutes) 0 30
Vertical angles are equal
2x + 40 = 8x - 32
40 + 32 = 8x - 2x
72 = 6x
72/6 = x
12 = x
2(12) + 40 = 24 + 40 = 64
8(12) - 32 = 96 - 32 = 64
so angle 1 is 64 and angle 2 is 64
Answer:y=1/2x + 5/2
Step-by-step explanation:
2+4 is 8 that should be your answer :)
All triangles have to equal 180 degrees. 52+34 equals 86. 180-86=94. So the angle must measure 94 degrees. =) Looks like you would've selected the right answer. =D
