According to the graph, the value of the constant in the equation below is 80 and is denoted as option D.
What is a Graph?
This is defined as a pictorial representation of data or variables in an organized manner.
From the equation: Height = constant/width
We can pick any point(4,20) on the graph.
20 = c/ 4
c = 20 × 4 = 80

Answer:
A, B, E
Step-by-step explanation:
I'm not too sure about B, but A and E are definitely true
Answer:Jason is 5 years old.
John is 4 years old.
Jackson is 12 years old.
Step-by-step explanation:
Let x represent the age of Jason.
Let y represent the age of John.
Let z represent the age of Jackson.
The ages of three siblings Jason John and Jackson totals 21 years. It means that
x + y + z = 21 - - - - - - - - - - -1
Jason is one year older than John. It means that
x = y + 1
Jackson is three times as old as John. It means that
z = 3y
Substituting x = y + 1 and z = 3y into equation 1, it becomes
y + 1 + y + 3y = 21
5y = 21 - 1 = 20
y = 20/5 = 4
x = y + 1 = 4 + 1
x = 5
z = 3y = 3 × 4
z = 12
The answer would be C. The line is best fit so the Y-intercept wouldn't show EXACTLY how much it would cost, just around how much it would cost. (Approximately)
