Answer: y = 1/2x + 3
Step-by-step explanation:
Use the equation y=mx +b
Find the slope (m) of the line by finding the difference in y over the difference in x. Or "rise over run".
The y-intercept (b) is 3 (when x is zero, it is y).
To find LCM
factor and eliminate ones already represented
1=1
2=2
3=3

Answer:
10.5 I think
Step-by-step explanation:
the platform is 42ft so if you divide 42 by 4 you get 10.5
- Here, t represents time, which is the input of the function, so we know that 10 is the time in minutes.
- h(t) represents the altitude, which is the output of the function after time, t.
- So, we need to substitute 10 into 210 -15t in place of t.
- On simplifying 210 -15(10), we get that 60 is the altitude in feet. So, after 10 minutes, the hot air balloon is at 60 feet.
