What is -x-6y=6 in slop intercept form?
maks197457 [2]

-x-6y=6

y=mx+b- slope

slope is also m

b is the y-intercept

move -x to the other side

-x+x-6y=x-6

-6y=x-6

divide both sides by -6 to get y by itself

-6y/-6=x/-6-6/6-6

answer:

y=x/-6-1 or y=-1/6x-1

SOLVE<br>S. 'x+4 - 3x = 1+x​
saw5 [17]

Answer:

x =1

Step-by-step explanation:

x + 4 - 3x = 1 + x

Combine like terms:

x - 3x

==> -2x

4 - 2x = 1 + x

Subtract x to each side:

-2x - x        x - x

-3x                 0

4 - 3x = 1

Subtract 4 from each side:

4 - 4             1 - 4

0                   -3

-3x = -3

Divide -3 from each side:

\frac{-3x}{-3}  = \frac{-3}{-3}

==> x = 1

Answer:

The no. of possible handshakes takes place are 45.

Step-by-step explanation:

Given : There are 10 people in the party .

To Find: Assuming all 10 people at the party each shake hands with every other person (but not themselves, obviously) exactly once, how many handshakes take place?

Solution:

We are given that there are 10 people in the party

No. of people involved in one handshake = 2

To find the no. of possible handshakes between 10 people we will use combination over here

Formula : ^nC_r=\frac{n!}{r!(n-r)!}

n = 10

r= 2

Substitute the values in the formula

^{10}C_{2}=\frac{10!}{2!(10-2)!}

^{10}C_{2}=\frac{10!}{2!(8)!}

^{10}C_{2}=\frac{10 \times 9 \times 8!}{2!(8)!}

^{10}C_{2}=\frac{10 \times 9 }{2 \times 1}

^{10}C_{2}=45

No. of possible handshakes are 45

Hence The no. of possible handshakes takes place are 45.
