First, pass all the rate of inflation to ballons/hour
John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
Answer: option A)
Answer:
There is approximately 0.83*100 or 8.3% chance of rolling an even number (2 or 4 or 6) followed by a four with a six sided die. A single 6-sided die is rolled. What is the probability of rolling a number greater than 3 or an even number?

Point Slope Form: y - y₁ = m(x - x₁)
slope = m
Slope Intercept Form: y = mx + b
Steps:
∴ Plug in the slope and point into point slope form.
∴ Convert the equation from point slope form to slope intercept form.
1). y + 1 = 2(x + 2) 2). y + 3 = -1/2(x + 2)
y + 1 = 2x - 4 y + 3 = -1/2x -1
- 1 - 1 - 3 - 3
------------------------------- ---------------------------------
y = 2x - 5 y = -1/2x - 4
I hope that this helps you understand more about slope intercept form and point slope form of lienar lines!
