<span>-2x+4y=12 <=> y = (-1/2)x + 3 => the slope of given line is -1/2;
the new line and the given line are perpendicular =>( the slope of new line )*(-1/2) = -1 =>
the slope of new line is 2;
the equation of the new line is y -0 =2( x -0) <=> y = 2x.</span>
First, you know that she earned a total of 73 dollars for 6 hours of work and how 46 dollars was from tips. So what you do first is to subtract 46 from 73 leaving you 27. Since she worked 6 hours, you would have to divide that with 27. 27 divided by 6 is 4.5 The waitress earns $4.50 for her hourly wage.
Answer:
I'm not to sure but I think it's 39 11/20
Step-by-step explanation:
1/5 + 1/4 you have to get a common denominator which would be 20 and then you add the numerators to get 9. Then you would subtract 40 from 9/20 and have to get the common denominator again which would be 800/20 - 9/20 which is 751/20 simplified to 39 55/100 simplified even more to 39 11/20. I haven't done fractions for a while so it might be wrong. I hope I helped!
