What is the greatest common factor (GCF) of the numerator and denominator
pav-90 [236]

Answer:

C. x + 6

Step-by-step explanation:

Start by factoring completely the numerator and the denominator.

2x + 12 = 2(x + 6)

x^2 + 7x + 6 = (x + 1)(x + 6)

The only common factor is x + 6, so the GCF is x + 6

I want to be earning an annual salary of $100,000 when i retire in 10 years. i have been offered a job that guarantees an annual
AURORKA [14]

For this case we have a function of the form:

y = A * (b) ^ x

Where,

A: starting salary

b: salary growth rate

x: number of years

y: salary after x years.

Substituting values we have:

100000 = A * (1.04) ^ {10}\\

From here, we clear the value of A.

We have then:

A=\frac{100000}{1.04^{10}}

A=67556.42

Answer:

the lowest salary that i should request in order to meet my goal is:

A=67556.42
