Answer:
y=-1/3x-5
Step-by-step explanation:
Find the slope(m), it is rise over run. this line doesnt "rise" per se; it goes down. You have to see at what rate. you find the rise with the y values. here you go from -3 to -7. the rise is <u>-4</u> units. the run you find with the x values. here you go from -6 to 6. the run is <u>12</u> units. your rise over run is the fraction <u>-4/12</u>. This can be simplified to <u>-1/3</u>. Now you find the y-intercept(b). the graph intercepts the y axis at (0,-5). now you plug it into y=mx+b. y=-1/3x-5
Answer:X1=1+-1+i(2)^1/2
x2=-1-i(2)^1/2
Step-by-step explanation
y=y
-2x+1=-x^2+4
x^2+4+2x-1=0
x^2+2x+3=0
Use
Ax^2+Bx+C=0
X1,X2=[-B+(B^2-4*A*C)^1/2]/2*A
A=1
B=2
C=3
x=[-2+/-(2*2-12)^1/2]/2
x=[-2+/-(-8`)^1/2]/2
x=[-2+/-2i(2)^1/2]/2
x1=-1+i(2)^1/2
x2=-1-i(2)^1/2
Advantages:
- It is easier for people to choose an option rather than to write an essay. The questionnaire reflects what the person is thinking and what the person's point of view is, which as a result makes it easier to analyze and conclude results
- A wide range of questions can be asked within one questionnaire, which makes it an effective way to conduct a survey/test
Disadvantages:
- A person has to read carefully in order to answer each question and sometimes there is lack of concentration by the person filling in the questionnaire
- It is slightly difficult to write an effective questionnaire, that would able to test a vast knowledge/ conduct a survey so that an effective analysis can be done
