Answer:
third option
Step-by-step explanation:
Given
x² + 4x - 4 = 0 ( add 4 to both sides )
x² + 4x = 4
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 4 + 4, that is
(x + 2)² = 8 ( take the square root of both sides )
x + 2 = ± 
= ± 2
( subtract 2 from both sides )
x = - 2 ± 2
Answer:
y = -1/5x +32/5
Step-by-step explanation:
The slope intercept form of the equation of a line is
y = mx+b
we know m = -1/5
y = -1/5x+b
We know a x and y on the line
7 = -1/5(-3) +b
7 = 3/5 +b
Subtract 3/5 from each side
35/5 -3/5 = b
32/5 =b
So the equation is
y = -1/5x +32/5
The answer to the question that needs to go on the top is 33

It involves the use of quantitative templates, diagrams, or summaries in such a given set of experimental data or real-liability for research. This research method is used for gathering, analyzing, assessing, or making judgments.
- The statistics are mostly a summary description and the entire nation is represented in a parameter.
- It is 78 figure is a statistical figure based on a survey of 10,000 people, that's why choice d is correct.
