Answer:
Step-by-step explanation:
The given curve crosses the x-axis in two places, (-2, 0) and (0, 0), which are the zeros. This parabolic curve opens up and has its vertex (minimum) at (-1, -1).
3xy multiplied by the cube root of y^2
Well hmmm
let's say
b = amount of buzz cuts
f = amount of flat-top cuts
now, the total price for all the buzz cuts, since each one is $9, will then be 9*b or 9b
and the price for all flat-top cuts, since each is $13, will then be 13*f or 13f
one day Jerry made a total of $600, so we know, whatever "b" and "f" are, we know their price sum was 600,
thus 9b + 13f = 600
now, Jerry "<span>knows that he cut three times as many buzzes as flat-tops", so, whatever "f" is, "b" is three times that much, or 3*f, so b = 3f
now then </span>
<span>
solve for "f"</span>
