You have already asked this type of question. so now you know how to do this.
6 persons means he shook his hand with 5 people.
like wise add all handshakes
5+4+3+2+1= 15 handshakes
The linear combination method is the same as the elimination method. Let's multiply the second equation by -2 so the x terms cancel each other out. When we do that we get a system of
and
. The x-terms cancel each other out giving us
and y = -3. Now sub -3 into one of the equations to solve for x. x+2(-3)=-4, and x - 6 = -4. x = 2. So the solution for our system is (2, -3)
He could be 40321 years old.
If you divide 40321 by any odd or even number between 1 and 9, the remainder is 1.
I got this number by doing (2*3*4*5*6*7*8) + 1
Answer:
y=2x+y-int
Step-by-step explanation:
If the line is parallet to the defined by the given equation the slope of the unknown line is m=2.
Use this value of slope to calculate the y intercept. 2 = ( 2 - y-int)/4 - 0)
THus, your equation is y = 2x + y-int
