-2x + 4y = 22
-2x - 3y = 8

Subtract 2nd from 1st equation,
7y = 14
y = 14/7 = 2

Substitute it in 1st equation,
-2x + 4(2) = 22
-2x = 22 - 8
x = -14/2
x = -7

In short, Your Answer would be (-7, 2)

Hope this helps!

Insert 2 geometric means between -32 and 4

denis23 [38]

Answer:

16, -8

Step-by-step explanation:

Let the terms of the geometric sequence be $a, ar, ar^2, ar^3$ .

We know that $a=-32$ and thus, $-32r^3=4 \implies r=-1/2$ .

This means $ar=(-32)(-1/2)=16$ and $ar^2=-32(1/2)^2=-8$ .
