PLEASE HELP PLEASE WILL GIVE BRAINLIEST!!!!!!! A retain arithmetic sequence has the following explicit formula for the nth term:
SashulF [63]

In the given question,the given explicit formula is

a_{n) = 4+(n-1)(7)

Which is of the form

a_{n} = a +(n-1)(d)

So the constant difference is 7 here.

Now for the recursive formula

To find the next term, we need to add 7 to the current term, that is

a_{n} = a_{n-1} +7

So the correct option is B

Write in slope-intercept form an equation of the line that passes through the points (−5,−9) and (5,1).
o-na [289]

Answer:

y=x-4

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

m = (1--9)/(5--5)

m = (1+9)/(5+5)

    = 10/10

   = 1

The slope is 1

We have the slope and a point,so we can use point slope form

y-y1 = m(x-x1)

y-1 = 1(x-5)

y-1 = x-5

Add 1 to each side

y-1+1 = x-5+1

y=x-4

This is slope intercept form (y= mx+b)

PLEASE HELP ASAP WILL GIVE BRAINLIEST!!!!
max2010maxim [7]

Answer:

Step-by-step explanation:

y intercept is -6

the slope is already in it's fraction form but if you want it back to whole number it's y=1.33x-6

the slope is positive

Some plots you can put are (6, 2) and (12, 10)

Just start at (0, -6) and counts 4 up and 3 right

Whats 2x + y = 10 5x - y = 18 in elimination method
Naya [18.7K]
2x + y = 10
5x - y = 18

7x = 28

x = 4

2(4) + y = 10

8 + y = 10

y = 2

(4,2)
