4 HIKING: At 7:00 A. M., two groups of hikers begin 21 miles apart and head toward each other.
The first group, hiking at an average rate of 1.5 miles per hour, carries tents, sleeping bags,
and cooking equipment. The second group, hiking at an average rate of 2 miles per hour,
carries food and water. Let t represent the hiking time. (Non-anonymous question) * r.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
