I have a Casio FX-9750GIII

I can't seem to get the equation solver to work, I'm mainly afraid of something similar to Chapter T8 appearing on states.

$y^2=1025-40x$
$x^2=1025-50y$

Does anyone with the model know how to get the calculator to solve the equation above?

Thanks

Can you take square root of first equation and solve for $y$ on second, then graph to find intersection? Or is there a intersection, graphing, or radical problem that doesn't work along with the calculator?

Wait are graphing calculators allowed on mathcounts? I thought they weren't? I recently purchased a "TI-30X" so I am also making sure that specific calculator is allowed?

Any calculator is basically allowed. Even Ti-Nspires

yep!
ppl bring all sorts of fancy cubic equation solving calcs cuz maybe they could be useful, y'know?

if you have it then you already won the game if it is like a polynomial question like number 8 target chapter.. or else you would bash for the whole 6 minutes.

I got a CASIO graphing calculator, and I honestly didn't consider that there might be a rule against them. However, they didn't kick me out, so I was fine.

What calculator do you use?

The problem is that i can't find the intersection

I use Ti-84 cuz of speed. But, I search it up, and the AI said there was a way, so are u sure there’s no way to find intersection for your calculator.

I just had to rearrange everything as
$y = \sqrt{1025-40x}$
and
$y=\frac{1025-x^2}{50}$

Cuz for some reason casio just can't find an intersection if it's in the form y = something and x = something

It also wont let me type equations in as $y^2=1025-40x$

Wdym, yeah your equations are right, can you not plug in both of those into your calculator? Wdym x=smth, dw no calculator can solve both x= and y=, you gotta solve for y on both
