Answer:
−(d+1)>3
Step 1: Simplify both sides of the inequality.
−d−1>3
Step 2: Add 1 to both sides.
−d−1+1>3+1
−d>4
Step 3: Divide both sides by -1.
> 
d < -4
Answer:
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Step-by-step explanation:
Let x = Courtney's walking speed
then
(x + 1) = Brandi's walking speed
:
Time = Distance/speed
Brandi walks 6.5 mi time = Courtney walks 5 mi time
6.5/x + 1 = 5/x
Cross multiply
6.5x= 5(x+1)
6.5x= 5x + 5
6.5x - 5x = 5
1.5x = 5
x = 5/1.5
x = 3.33 mph is Courtney's walking speed
Note that:
(x + 1) = Brandi's walking speed
3.33mph + 1 = 4.33mph
Therefore,
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph

The unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.
<h3>How to Find the Unit Rate of a Proportional Graph?</h3>
The unit rate of a proportional graph is determined using the formula below:
k = y/x, where x and y are coordinates of any point on the line.
Thus, to find the unit rate of a proportional graph, pick the coordinates of any point on the line and find k = y/x.
From the given graph, let's pick the indicated point on the line having the coordinates, (12,16). Find k:
Unit rate (k) = 16/12
Simplify
Unit rate (k) = 4/3
Therefore, the unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.
