The equation y=0.02x+250 gives the weekly income y in terms of sales x.
Step-by-step explanation:
Given,
Weekly salary of real estate agent = $250
Commission rate = 2%
Let,
x be the sales per week.
y be the total weekly income.
Amount of commission = 2% of sales per week
Amount of commission = 
Amount of commission = 0.02x
Total weekly income = Amount of commission + Weekly salary

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Answer:
D. n>-7
Step-by-step explanation:
The equation for a parabola with vertex (h, k) and vertical scale factor "a" is
y = a(x -h)² + k
One parabola with vertex (6, 9) is
y = (x-6)² +9
The answers are:
13. |3y|=9, y<0
14. |x|=2, x>0
The Maximum amount of minutes she could use would be 210
Formula:
0.05x + 25 <= 35.50
