8-2 = 6 per plate profit
6x
they spent 150 so it would be -150
6x - 150 = 2400
Lines of symmetry in regular polygons can be formed from a vertex to an opposite vertex or a vertex to an opposite midpoint.
A definitely has to be one because it's a fact and you need to know what it looks like. B isn't true because the greatest integer function rounds down values. C is also not correct because a one-to-one graph has one x-value for every y-value. This one doesn't. D has to be true because f[0] = 0 because the Greatest Integer Function requires it to be. And E is also correct because that's in the definition of a Greatest Integer Function. So, your answers are A, D and E.
Answer:
y=2x+3
Step-by-step explanation:
y-2x=3
y=2x+3
a^2+b^2=c^2
where c=25 m. and a=2b-10 m.
substitute
(2b-10)^2+b^2=25^2
4b^2-40b+100+b^2=625
5b^2-40b+100=625
divide both sides by 5
b^2-8b+20=125
subtract 20 from both sides
b^2-8b=105
complete the square
take half of 8 and square it=16
i hope this helps =3
