The number of guitar lessons that can be completed in 7 months is 2(7) = 14.
Answer:
h = Hannah's age
h - 2 = Anthony's age
Hannah is 47, Anthony is 45
Step-by-step explanation:
Using one variable and an expression with the same variable, you can find the sum of the siblings ages:
h = Hannah's age
h - 2 = Anthony's age
h + (h - 2) = 92
Combine like terms: 2h - 2 = 92
Add '2' to both sides: 2h - 2 + 2 = 92 + 2 or 2h = 94
Divide by 2: 2h/2 = 94/2
Solve for h: h = 47 years old (Hannah)
h - 2 = 45 years old (Anthony)

No this is not a function. A function is a set of inputs, x-values with a single output. Since 13 has two outputs, 4, and -4, this is not a function.
