That would be 13.25, 13+1/4
= 13+(1 divided by 4 which is 0.25)
= 13+0.25
Which is 13.25 so your answer is 13.25, good luck hope that helps :D
Adding both equations cancels y:
<span>4x + 8y = 16
</span><span>4x - 8y = 0
-----------------+
8x = 16 => x=2
filling in x=2 in the first equation gives:
4*2 + 8y = 16 => 8y = 8 => y=1
So (2,1) is the (x,y) pair that solves the two equations. Answer C.</span>
No BC it's ssa............
The domain is "x", because that is what you input
hope this helps
They are because 2.7 squared + 3.6 squared = 4.5 squared (=20.25)
Pythagoras Theorem is that a squared + b squared = c squared
So the 2 smallest numbers squared will equal the larger one squared if it is a pythagoreom triple
