Answer:
option b
Step-by-step explanation:
replace x and y with the x and y of the ordered pair
option a: 2(4)+4(5)=6(4)-5
solve
8+20=24-5
28=19 not true
option b:2(5)+4(4)=6(5)-4
solve
10+16=30-4
26=26 true

The class which generally had the highest pulse of students recorded by the science teacher after climbing the stairs is class 3.
<h3>What is box plot representation of data?</h3>
Box plot is the way of representation of data which gives the graphical image of the data set to understand better.
The minimum and the maximum values in the box plot is plotted at the end points.
- A science teacher recorded the pulse of each of the students in her classes after the students had climbed a set of stairs.
- She displayed the results, by class, using the box plots shown.
In this box plot, the class 3 has the highest value compare to all the box plot.
Thus, the class which generally had the highest pulse of students recorded by the science teacher after climbing the stairs is class 3.

The function rule that relates the number of miles traveled to the hours driven is d = 55t
<h3>What is speed?</h3>
Speed is the ratio of distance traveled by a body to the time taken.
The formula for calculating distance is expressed as:
Given that the speed is 55 miles per hour
55 = d/t
Cross multiply
d = 55t
Hence the function rule that relates the number of miles traveled to the hours driven is d = 55t
