Do the data in this table represent a constant rate of change
1 answer:
The data on the table represents a constant rate
<h3>How to determine if the table has a constant rate?</h3>The table that completes the question is added as an attachment
On the table, we have the following points
(x, y) = (2, -5), and (4, 5)
The rate of change of the points is then calculated as
k = (y₂ - y₁)/(x₂ - x₁)
Substitute the known values in the above equation
So, we have
k = (5 + 5)/(4 - 2)
Evaluate
k = 5
Also from the table, we have the following points
(x, y) = (7, 20), and (11, 40)
The rate of change of the points is then calculated as
k = (y₂ - y₁)/(x₂ - x₁)
So, we have
k = (40 - 20)/(11 - 7)
Evaluate
k = 5
In both case, the result is 5
This means that the table has a constant of rate

Answer:
Step-by-step explanation:
1) x² + 6x + 11 = 0
a = coefficient of x² = 1
b = coefficient of x = 6
c = Constant = 11
Roots = (-b ± √b² - 4ac)/2a
Roots =
2) 2x² - 16x = 50
Divide the whole equation by 2
x² - 8x = 25
Divide the coefficient of x (i. e 8 ) by 2 = 8/2 = 4, Now add 4 to both sides of the equation
x² - 8x + 4 = 25 + 4
x² - 2*4*x + 2² = 29
(x - 2)² = 29
Take square root both side
