Answer 1

Answer:

Answer:

1)For, m = 3/4 , (0,4) , 4y - 16 - 3x = 0 is the equation of line.

2)For, m = 4 , (-2,-5) , y - 4x - 4 = 0 is the equation of line.

3)For, m = -1/3 , (4,-1) , x + 3y -1 = 0 is the equation of line.

Step-by-step explanation:

If m is the slope and (x0,y0) is the point on any given equation, then

by POINT SLOPE FORMULA:

The line equation is given as (y - y0) = m (x -x0)

Now , here:

1) m = 3/4 , (x0, y0) = (0.4)

So,, the equation of line is $(y-4) = (3)/(4) (x-0)\nor, 4(y-4) = 3x$

on simplification, 4y - 16 - 3x = 0 is the equation of line.

2) m = 4 , (x0, y0) = (-2.-5)

So,, the equation of line is $(y-(-5)) = 4 * (x-(-2))\nor, (y+4) = 4(x+2)$

on simplification, y - 4x - 4 = 0 is the equation of line.

3) m = -1/3 , (x0, y0) = (4, -1)

So,, the equation of line is $(y-(-1)) = (-1)/(3) (x-4)\nor, 3(y+1) = -(x-4)$

on simplification, x + 3y -1 = 0 is the equation of line.

The panthers team won exactly 2 of its first 9 games. By winning all its remaining N games, the Panthers ended with victories in exactly half of the games it played. What number does N represent?

Answers

Answer:

Step-by-step explanation:

2 out of 9 games won

After the N games, the games won would be HALF. Thus, we can write a ratio and solve for the variable N:

$(2+N)/(9+N)=(1)/(2)$

Now we cross multiply and solve for N [the number of remaining games that all are won]:

$(2+N)/(9+N)=(1)/(2)\n2(2+N)=1(9+N)\n4+2N=9+N\n2N-N=9-4\nN=5$

N represents 5
