A hair stylist charges $30 for a woman's haircut and $10 for a man's haircut. It takes 1 hour to cut a woman's hair and 1/2 hour to cut a man's hair. Based on the
customer needs, the stylist must schedule at least 6 woman's hair cuts per day and
no more than 5 man's hair cuts per day. The stylist works for up to 10 hours per day.
If x represents the number of woman's hair cuts and y represents the number of
man's hair cuts, which of the following are the correct constraints?

what do u need to know

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

b if for most of the graph

d if y intercept
