Answer:

Step-by-step explanation:
Assume your graph looks like the one below.
1. Calculate the equation of the straight line
The slope-intercept equation for a straight line is
y = mx + b
where m is the slope of the line and b is the y-intercept.
The line passes through the points (0,2600) and (30, 2300)
(a) Calculate the slope of the line

(b) Locate the y-intercept
The y-intercept is at 2600 ft
(c) Write the equation for the line
h = -10t + 2600
(d) Calculate the time to 2000 ft

Shelley will be at 2000 ft 60 s after opening the parachute.
Answer:
8 meters
Step-by-step explanation:
80 centimeters is like a one hundredth of 8 meters
Answer:24
Step by step explanation:
The last bc the + and - are different that means it will be subtracted.
Plug in 0.9 for x
-(x) + 2.7
- (0.9) + 2.7
simplify
2.7 - 0.9 = 1.8
1.8 is your answer
hope this helps
