The Half Dome at National Park is 8,840 feet high. Due to strong winds, James was able to scale only 70% of the total distance. How many more feet does he need to scale to complete hike?

y=mx+b is the final answer!   : )

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
