Step-by-step explanation:
Surface area of what shape or solid ?
Answer:
y = -3x
Step-by-step explanation:
Substitute the numbers into the point-slope form equation:
y - 0 = -3(x - 0)
y = -3x

Answer:
When number of games downloaded is at least 3
Step-by-step explanation:
Let x = number of games downloaded
Members = 50 + 2x
Non members = 20x
50 + 2x = 20x
50 = 20x - 2x
50 = 18x
x = 50/18
x = 2.78
At x = 2.78, both members and non members are paying the same amount
For members to make profits, the value of x must be greater than 2.78
Approximately x = 3
Check:
Members = 50 + 2x
= 50 + 2(3)
= 50 + 6
= 56
Non members = 20x
= 20(3)
= 60
In order to write an equation you need to find the y-intercept. the way you do this is by plugging in the value 2 and the point into y=mx+b and solving for b. once you plug everything in you get 5=2(1)+b. solving from here you get b=3. putting everything together you get y=2x+3
