Answer:

y = -x -1

Step-by-step explanation:

x1= 0, y1= -1

$slope = \frac{x - x1}{y - y1} = \frac{x - 0}{y - ( - 1)} = \frac{x}{y + 1}$

-1 = x/(y+1)

-1 (y+1) = x

y+1 = -x

y= -x -1

A total of 600 advertisements were sold for a certain magazine. If 30 percent of the first 200 sold were in color, 20 percent of

solong [7]

Answer:

%35 of them were in color

Step-by-step explanation:

Since 30 percent of the first 200 sold were in color, 200x30/100 = 60 of them were in color.

Since 20 percent of the next 300 sold were in color, 300x20/100 = 60 of them were in color.

Since 90 percent of the last 100 sold were in color, 100x90/100 = 90 of them were in color.

In total, 60 + 60 + 90 = 210 out of 600 were in color.

The percentage is: $\frac{600}{100}$ = $\frac{210}{x}$ → x = $\frac{21000}{600}$ = 35
