Answer:
x=7
Step-by-step explanation:
Vertical lines are lines that go up and down
They are of the form x =
The x coordinate of the point is 7
x=7
Answer:
see explanation
Step-by-step explanation:
(a)
x² - 6x + 4 = 0 ( subtract 4 from both sides )
x² - 6x = - 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = - 4 + 9
(x - 3)² = 5 ( take the square root of both sides )
x - 3 = ± ( add 3 to both sides )
x = 3 ± ← exact solutions
(b)
4x² + 16x + 9 = 0
To complete the square
The coefficient of the x² term must be 1
Factor out 4 from 4x² + 16x
4(x² + 4x) + 9 = 0
add/subtract ( half the coefficient of the x- term )² to x² + 4x
4(x² + 2(2)x + 4 - 4 ) + 9 = 0
4(x + 2)² - 16 + 9 = 0
4(x + 2)² - 7 = 0 ( add 7 to both sides )
4(x + 2)² = 7 ( divide both sides by 4 )
(x + 2)² = ( take the square root of both sides )
x + 2 = ± = ± ( subtract 2 from both sides )
x = - 2 ± ← exact solutions
Answer:
10 miles
Step-by-step explanation:
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
6^2 + 8^2
36 + 64 = 100
square root = 10
Since P105a06.sas are the same statistics in the given report and data for this lab, we can infer and logically deduce that the first 5 rows in the data means the statistics are different.
<h3>What is SAS?</h3>
SAS is an abbreviation for Statistical Analysis System and it can be defined as a statistical software suite which was developed at North Carolina State University by SAS Institute for the following field of study:
