Answer:
31 customers
Step-by-step explanation:
Let he had x customers when he started,
given that, 2x+11=73
=>2x=62.. Subtracting 11 from both sides
=> x=31 ...Dividing both sides by 2
Hence he had 31 customers when he started.

Answer:
geometric
Step-by-step explanation:
The signs of the terms alternate, so it cannot be an arithmetic sequence.
The ratios of terms are ...
6/-3 = -12/6 = 24/-12 = -2
The terms have a constant ratio of -2, so the sequence is geometric.
Answer:
The independent variable is x
Step-by-step explanation:
In the equation y = m x + b
- m is the rate of change ⇒ constant
- b is the initial value ⇒ constant
x is the independent variable because it does not depend on any value
y is the dependent variable because it depends on the value of x
Let us solve the question
∵ 5x + 2y = 150
→ Put it in the form above by subtracting 5x from both sides
∵ 5x - 5x + 2y = 150 - 5x
∴ 2y = 150 - 5x
→ Divide each term by 2 to make the coefficient of y equal 1
∴ y = 75 - 2.5x
∴ y = -2.5x + 75
→ Compare is by the form above
∴ m = -2.5 and b = 75
∴ x is the independent variable (domain)
∴ y is the dependent variable (range)
