They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
Answer:
m= -7/5
Step-by-step explanation:
(x1,y1)=(3,4)
(x2,y2)=(8, -3)
Use the slope formula:
m = y2 - y1
x2 - x1
(-3-4)/ (8-3)
= -7/5
Answer:
The height of the building is approximately 29 feet
Step-by-step explanation:
We are given
A surveyor is standing at a distance of 50 feet from the base of a building
so, b=50 feet
Let's assume height of the building is h feet
angle of elevation is 30°

we can use trig to find h

now, we can plug values



Answer:
The answer is 15
