Question

I need these anwsers asap I'll give 100 points!!

Answer 1

11.
slope intercept is solve for y

12x+y=-5
y=-12x-5



12. y-y1=m(x-x1)
a point is (x1,y1) and slope is m

y+2=(-2/3)(x+3)
y+2=(-2/3)x-2
y=(-2/3)x+0

13.
slope find
(-1-2)/(-5-0)
-3/-5=3/5

given (0,2)
yint is 2
y=mx+b
b=yint

y=(3/5)x+2



14.
initially (x=0) y intercept is 9
speed is slope is -6 because getting close to home

y=-6x+9

a. standard form is solve for constant
6x+y=9

b. y intercpet is 9 that is how far you are away from home at start

c. x intercept is where y=0 or when you reach home
that is
0=-6x+9
6x=9
x=3/2
at 3/2 hours or 1.5hours

Answer 2

Answer:

It can be helpful to see completed examples before writing, in order to examine what makes for an effective piece. See how these intros give some context before posing the topic and lead naturally into the body paragraphs, where the evidence will be listed. You can imagine how the author has organized the rest of the piece.

"We buried my cousin last summer. He was 32 when he hanged himself from a closet coat rack in the throes of alcoholism, the fourth of my blood relatives to die prematurely from this deadly disease. If America issued drinking licenses, those four men—including my father, who died at 54 of liver failure—might be alive today. That is a good example piece  some steps that are helpful.
