The common point between y = 2x + 5 and y = (1/2)x + 6 will have the same values for x and y.
Therefore, set the two y expressions equal to obtain
2x + 5 = (1/2)x + 6
Subtract (1/2)x from each side.
(3/2)x + 5 = 6
Subtract 5 from each side.
(3/2)x = 1
Multiply each side by 2/3.
x = 2/3.
From the first equation, obtain
y = 2*(2/3) + 5 = 19/3.
The common point is (2/3, 19/3). It is not equal to (3, 1/2).
Answer: False
Answer:
angle of elevation will be 
Step-by-step explanation:
Given,
height of tower = 150 ft
height of tower = 1200 ft
So, total height of peak of tower = 1200 + 150
= 1350 ft
distance of user from cell tower = 5 miles
= 5 x 5280 feet
= 26,400 feet
Since the height of user from sea level = 400 ft
so, height of peak of tower with respect to user = 1350 - 400 ft
= 950 ft
If the angle of depression is assumed as
, then we can write




So, the angle of elevation will be 
0.8 this is the answer 3-(22 tenths)=0.8
