Answer:
For the r alone
Step-by-step explanation:
Answer:the minimum rate is 1 mile per hour.
Step-by-step explanation:
Chanita wants to swim the 21-mile English Channel in 48 hours. Total number of miles that she covered on the first day is 9 miles. Total distance left for her to cover would be
21 - 9 =12 miles.
The next day, she has 12 hours of daylight to complete the remaining distance. Let x represent the minimum rate she has to swim on the second day to complete the distance.
Speed = distance/time
Therefore,
x ≥ 12/12
x ≥ 1
Your slope intercept form of this equation is : y= 1/4x-1. Which is the second graph
10ft
20ft
I hope that’s correct ☺️
Answer
y = (1/4)x - 5 or 4y - x + 20 = 0
Explanation
To get the rule required, we interpret the sentence and write it in a mathematical form.
5 less than one fourth of x is y
one fourth of x ⇒ (1/4)x
5 less than one fourth of x is y ⇒ (1/4)x - 5 = y
y = (1/4)x - 5
4y = x - 20
4y - x + 20 = 0
