Determine the standard form of the equation of the line that passes through (-6,6) and (3, -2)
viva [34]

Answer:

 (8/9)x +y = (2/3)

Step-by-step explanation:

General standard form of an equation of a line is y = mx+b, where m is the slope of the line and b is the y-intercept ( where the line intersects the y-axis.)

For points (-6, 6) and (3, -2)

m= (y2-y1)/(x2-x1) = (-2-6) / (3-(-6)) = -8 / 9

y = (-8/9)x +b

Substitute any of the 2 points to find b. If we choose (x=3, y= -2) then

-2 = (-8/9)*3 +b, simplify (-8*3)/9

-2 = (-8/3)+b, add (8/3) to both sides

-2+(8/3) = b, find the common  denominator and add the fractions

(-6+8)/3 =b

2/3 =b

The standard form of the equation of the line that passes through (-6,6) and (3, -2) is (8/9)x + y = (2/3)

A theatre has the capacity to seat two levels. The circle and the stalls. The ratio in the number of seats in the circle compare
Nady [450]

Answer:

<u>76.19%</u> is the percentage of occupancy on last Friday.

Step-by-step explanation:

<u><em>The question is incomplete, so the complete question is below:</em></u>

A\ theatre\ has\ the\ capacity\ to\ seat\ two\ levels. \ The\ circle\ and\ the\ stalls.\ The\ ratio\ in\ the\ number\ of\ seats\ in\ the\ circle\compared\ to\ the\ number\ of\ seats\ in\ the\ stalls\ is\ 2:5.\ Last\ Friday,\ the\ audience\ occupied\ all\ the\ 528\ seats\ in\ the\ circle\ and\ 2/3\ of\ the\ seats\ in\ the\ stalls.\ What\ is\ the\ percentage\ of\ occupancy\ of\ the\ theatre\ last\ Friday?

Now, to get the percentage of occupancy of the theatre last Friday.

Let x be all the seats in the stalls.

Total number of seats in the circle occupied by audience last friday = 528.

<em>According to question, 2 : 5 is the ratio in the number of seats in the circle compared to the number of seats in the stalls.</em>

<em>So, 2 is equivalent to 5.</em>

<em>And, 528 is equivalent to </em>x<em>.</em>

Now, to get the number of stalls by using cross multiplication method:

\frac{2}{5} =\frac{528}{x}

<em>By cross multiplying we get:</em>

<em />2x=2640<em />

<em>Dividing both sides by 2 we get:</em>

x=1320.

Total number of seats in the stalls = 1320.

Now, to get the people occupied seats in the stalls on last friday:

\frac{2}{3} \ of\ 1320\\\\=\frac{2}{3} \times 1320\\\\=880.

Thus, people occupied 880 seats in the stalls on last friday.

So, the total number of seats in the circle and stalls:

1320+528\\\\=1848.

And, the total number of seats people occupied last friday:

528+880\\\\=1408.

Now, to get the percentage of occupancy of the theatre last Friday:

\frac{1408}{1848} \times 100

=\frac{140800}{1848} \\\\=76.19\%.

Therefore, 76.19% the percentage of occupancy on last Friday.
