he needs at least 5800
5800/725
8
so he must sell at least 8 cars
There are only 45 cars on the lot, so that is the max he can sell
Choice C
8<=x<=45
Answer: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" the y-intercept.
Since the given line has a y-intercept at (0,-15), then:

The formula for calculate the slope is:

Knowing that the given line contains the points (0,-15) and (-4,-3), we can calculate the slope. This is:

Substituting values into
, we get that the equation of the line in Slope-Intercept form is:

Answer:
12 red balls
4 yellow balls
2 blue balls
2 green balls
Step-by-step explanation:
set no. of yellow, blue, red and green ball as y, b, r, g respectively
y=2b
r=3y
g=b
y+b+r+g = 20 (translate all of them into b (smallest in qty)
2b + b + 3(2b) + b = 20
10b = 20
b =2
y = 4, r = 12, b =2, g =2
