compute each sum below. if applicable, write your answer as a fraction.
5+5(-2)+5+(-2)^2++5(-2)^7=
9
∑ (1/4i)=
i=1

First equation is -425

Second equation is 11.25

Step-by-step explanation:

First equation we can write as

computing

When i=0 ->

When i=1 ->

...

When i=7 ->

then replacing each term we have

For the second equation we'll have 9 terms, solving in a similar fashion

When i=1 ->

When i=2 ->

When i=3 ->

...

When i=9 ->

So we have 0.25 + 0.50 + 0.75 + 1.00 + 1.25 + 1.50+ 1.75 +2.00 +2.25

hope i with whatever it is that you need! : )

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
