To cancel \(ab\) you can add the equations together:

 \(2a=10 \Rightarrow a=\color{blue}{\boxed{5}}\) 

Now plug in \(a\) into one of the equations to get:

\(5+5b=250 \Rightarrow 5b=245 \ \text{so} \ b=\color{blue}{\boxed{49}}\).

I hope that helped! 

The only solution works out to be  \(x=2\).

Put the terms with \(x\) on one side and the numbers on the other:

\(2x+x+7x \le 12+18+5\)

which simplifies to \(10x\le35\) 

So \(x= \dfrac{7}{2}\). 

I hope that helped!

First, simplify the function to: \(x=2y^2-13y-1\)

Setting \(x'=0\), \(4y-13=0\) so \(y=\dfrac{13}{4}\). Your next step is to find \(x\). Then \((x,y)\) is the vertex.

Good answer.

Hi guest,

Good answer.

Anyways,      \(\boxed{n=3}\)

\(x=120\)                                            \(240000=2000x \)                   \(\dfrac{2000}{60}=\dfrac{6000}{x}\)

Thanks, I bumped into the same promblem and this helped alot.
