what is the explicit formula for this sequence -9,-3,3,9,15,... A) an=(-9)+(n-1)6 B)an=6+(n-1)(-9) C)an=(-9)+(n-1)(-6) D)an=21+(n-1)6

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
