(5400 bulbs)/(72 bulbs/min) = 75 min
It would take 75 minutes for the machine to make 5400 light bulbs.
The rules of this problem will be as follow:
we have a * b = x
1) If a > 1 and b > 1 ⇒⇒⇒ x > a and x > b
2) If a > 1 and b < 1 ⇒⇒⇒ x < a and x > b
3) If a < 1 and b < 1 ⇒⇒⇒ x < a and x < b
4) If a = 1 and b > 1 ⇒⇒⇒ x > a and x = b
5) If a = 1 and b < 1 ⇒⇒⇒ x < a and x = b
=================================================
2a) (13/4) * (5/8) = x ⇒⇒⇒⇒ rule (2)
∴ x < (13/4) and x > (5/8)
2b) (4/3) * 6 = x ⇒⇒⇒ rule (1)
∴ x > (4/3) and x > 6
2c) (2/5) * (1/7) = x ⇒⇒⇒⇒ rule (3)
∴ x < (2/5) and x < (1/7)
2d) (5/8) * (7/7) = x ⇒⇒⇒ rule (5)
x = (5/8) and x < (7/7)

Answer:
1.199 ≤ x ≤ 1.201
Step-by-step explanation:
You want ...
|y -7| ≤ 0.005
Substituting the expression for y, you have ...
|5x+1 -7| ≤ 0.005
|x -1.2| ≤ 0.001 . . . . . simplify, divide by 5
-0.0001 ≤ x -1.2 ≤ 0.001 . . . . . "unfold" the absolute value
1.199 ≤ x ≤ 1.201 . . . . . . . . . . . .add 1.2
1. Find Slope
m = y2-y1/x2-x1
m = -6 - 5/2-4
m = -11/-2
m = 11/2
2. Write equation with know information
y = mx + b
y = 11/2x + b
3. Choose any of the two points (doesn’t matter which in you choose) and replace the x and y value into the equation
y = 11/2x + b (4,5)
5 = 11/2(4) + b
5 = 22 + b
Use algebra and solve for b
5 - 22 = b
b = -17
State all the information you know
m = 11/2 b = -17
Write the equation
y = 11/2x - 17
