Answer:
120
Step-by-step explanation:
-3y(-5y+10)
=15y^2-30y
y=4
15(4)^2-30(4)
=240-120
=120
Answer:
h = 5 (3+p)
Step-by-step explanation:
3 hrs = $45 + $15p
h = 45+15p / 3 (This was supposed to be a fraction)
h = 15 (3+p)/ 3 (This was supposed to be a fraction)
h = 5 (3+p) (You might use different variables from me)
hrs = hours
p = per person
Brainlist pls!
<span>y=-1/3x-6 slope = -1/3
</span><span>perpendicular lines, slope is opposite and reciprocal
</span><span>
so slope = 3
</span><span>passes through (–1, 5).
</span>
Point-slope<span> is </span><span>point-slope form </span><span>y-y₁=m(x-x₁)
so equation
y - 5 = 3(x + 1)

Answer:
Step-by-step explanation:
Given that the year is having only 365 days (not a leap year)
P(anyday as birthday) = 1/365
Any body will have a chance of having on Monday the birthday
=52/365 (assuming 52 Mondays as given)
Hence we can expect 365/52 = 7.019
i.e. if 7.019 persons are present there will be a definite chance for any other person to share this birthday
Hence atleast 8 people we need in a room so that you expect that there is going to be a shared birthday on a Monday of the year
