Answer:
y=2/3x-3
Step-by-step explanation:
using y=mx+c
since the intercept is negative,it affects the positive sign
If you can assume that the 2l bottle is full, then it holds 2000ml.
2,000 divided by 180 = 11.11.
So the answer is, if you don't spill any, 11 glasses may be filled, with a bit left over.
Any number inside the modulus sign becomes positive. This means
and so we have,

Solving these gives us


However if we check the second solution in the original equation we obtain
. This is false and so
can't be a solution.
Therefore the only solution is
.
(Note: I'm not sure why the second solution didn't work but when there's a modulus sign involved it always pays to check your final answers to be sure. I'll have a think about it but in case you find out before I do, I'd be interested to know in the comments.)
Given that the total profit is <u>$2400.00</u> and he made <u>$30.00</u> in profit for each share.
Number of shares = $2400 ÷ 30 = 80
Answer: He bought 80 shares
