Answer:

a1 = 4

a2= -2

a3 = -8

a4= -14

a5= -20

Step-by-step explanation:

a12= a1 + 11d

-62 = 4 + 11d

-62-4 = 11d

-66= 11d

d = \frac{-66}{11}\\

  = -6

a1 = 4

a2 = 4 - 6 = -2

a3 = 4 - (6×2) = -8

a4 = 4 - (6×3) = -14

a5 = 4 - (6×4) = -20

this graph shows the amount of rain that falls in a given amount of time. what is the slope of the line and what does it mean in
Galina-37 [17]

Answer:

-5/-2 or 2.5

Step-by-step explanation:

Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.

Write the simplified expression.
Vesna [10]

Answer:

343

Step-by-step explanation:

<u>Let's start simplifying with the numerator:</u>

(15-8)⁹

=7⁹

=40353607

<u>Now simplify the denominator :</u>

[(5+2)³]²

=[(7)³]²

=[343]²

=117649

<u>Now combine them :</u>

(15-8)⁹/ [(5+2)³]²

=40353607 / 117649

=343
