k=7

Hope i helped you!

Answer 2

Answer: 2/3+3k/4=71/12
= 71/12 - 2/3

3k/4 = 21/4
k = 21/4* 4/3
k = 7

The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking. Write a statement using function notation; let t represent the independent variable. Let h represent the function, and h(t) the dependent variable

Answers

h(t)=3t + k
Where k is a constant and h the distance covered and t the time taken

Answer: $h(t)=3t$

,where h(t) represents the distance we travel while hiking in time t which is the dependent variable.

Step-by-step explanation:

Given: The distance we travel while hiking is a function of how fast we hike and how long we hike at this rate.

The maintained speed while hiking= 3 miles per hour

If t represent the time of hiking which is independent variable, and h(t) represents the distance we travel while hiking which is dependent variable.

Then, $h(t)=3t$
