So for eliminating, you only solve for one variable first.

I solved for y, so I multiplied by -4 to eliminate the x.

Then I got y= -1

I then substituted that to one of the equations to get x.

The rule for this sequence is 'multiply by -6'.

Verification ↓

-3*(-6) $\stackrel\checkmark{=}$ 18

18*(-6) $\stackrel\checkmark{=}$ -108

So the rule for the sequence is 'multiply by -6'

And the Common ratio is -6.

Hope that made sense !!

Let f(x)=x-2 and g(x)=x2-7x-9 fins f(g(-1))

vlabodo [156]

The answer is -3 because you’re plugging g(x) into f(x). For every x there is in f(x), plug in g(x)’s equation. After you get another equation (simplified), which is x^2 -7x -11, plug -1 for every x and condense.
