Line 1
Points : (8,-4) and (2,-5)

To find the slope:
M = (y - y) / (x - x)
M = (-4 - -5) / (8 - 2)
M = (-4 + 5) / 6
M = 1 / 6 (answer)

Line 2

Points: (10, 9) and (15, -21)

M = (y - y) / (x - x)
M = (9 + 21) / (10 - 15)
M = 30 / -5
M = -30/5 (reduce this)
M= -6 (answer)

6x-21>3
Add 21 to both sides
6x>24
Divide 6 on both sides
X>4

14x+11>-17
Subtract 11 from both sides
14x>-28
Divide 14 on both sides
X<-2

Each vote in a certain election went to one of two candidates, X or Y. Candidate X received 624 of the votes cast by men, and Ca
alexandr1967 [171]

Answer:

The statement 2 is sufficient and total number of votes candidate X received is 946.

Step-by-step explanation:

Consider the provided information.

Candidate X received 624 of the votes cast by men, and Candidate Y received 483 of the votes cast by women.

The required table is shown below:

                            X              Y

Men                   624             ?

Women                ?              483

We need to find how many votes did Candidate X receive?

Statement 1: Candidate X received 50% cast by men .

That mean remain 50% cast by Candidate Y.

Therefore the complete table will look like this:

                            X              Y

Men                   624           624

Women                ?             483

But we need to find the number of votes received by Candidate X.

We don't have enough information to find the sum of the values under X column. Hence, the statement 1 is not sufficient.

Statement 2: Candidate Y received 60% cast by women.

Candidate Y received 60% cast that means Candidate X received 40% cast.

0.6 of x = 483

x = 805

Now 40% of 805 is:  322

Thus, the complete table is:

                            X              Y

Men                   624           624

Women             322            483

Total                  946

Hence, the statement 2 is sufficient.
