Ooh, fun
geometric sequences can be represented as

so the first 3 terms are



the sum is -7/10

and their product is -1/125

from the 2nd equation we can take the cube root of both sides to get

note that a=ar/r and ar²=(ar)r
so now rewrite 1st equation as

subsituting -1/5 for ar

which simplifies to

multiply both sides by 10r
-7r=-2-2r-2r²
add (2r²+2r+2) to both sides
2r²-5r+2=0
solve using quadratic formula
for


so
for 2r²-5r+2=0
a=2
b=-5
c=2




so

or

use them to solve for the value of a


try for r=2 and 1/2

or

test each
for a=-1/10 and r=2
a+ar+ar²=

it works
for a=-2/5 and r=1/2
a+ar+ar²=

it works
both have the same terms but one is simplified
the 3 numbers are

Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟

❃Incase you also forgot, what the slope formula is ☟

➊ First: We are going to be solving for the slope.

➋Second: We find the y-intercept.

➌Third: Plug in.

Answer:
im assuming its b because the quality for the pic is bad and i cant really see it
Step-by-step explanation:
6-4 because the equation for slope is m=y2-y1/x2-x1
