4x = -60 - 19y
-7x = -48 - 19y
Subtract the bottom equation from the top:
4x + 7x = -60 + 48 - 19y + 19y
Simplify:
11x = -12 -0y
11x = -12
Divide both sides by 11:
11x/11 = -12/11
Simplify:
x = -12/11
Then plug in x to solve for y:
4(-12/11) = -60 - 19y
Simplify:
-48/11 = -60 - 19y
Add 60 to both sides (keep in mind 60 = 660/11):
-48/11 + 660/11 = -60 + 60 - 19y
Simplify:
612/11 = 0 - 19y
612/11 = -19y
Divide both sides by -19 (keep in mind that dividing by -19 is the same as multiplying by -1/19):
612/11 • -1/19 = -19y/-19
Simplify:
-612/209 = y
y = -612/209
So, the answer is: (-12/11, -612/209)
A y=sin x maybe I am sorry
Step-by-step explanation:
your correct answer is the last one (x-1)/x²+3x+2.
the second equation lcm will be x²+3x+2 if you expand it .
hope this helps you.
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
