if x =7 then plug in 7 for x

4(7) - 2((7)+a) = 8

28 - 14 -2a = 8

14 - 2a = 8

-2a = -6

a = 3

What is the greatest common factor (gcf) of the numerator and denominator in the rational expression below? 7x+14/2x^2+x-6
Mashutka [201]
The answer is C. The numerator 7x+14 can be factored as 7(x+2). The denominator 2x^2+2x-6 can be factored as (x+2)(2x-3). The greatest common divisor of 7(x+2) and (x+2)(2x-3) is obviously x+2, which is contained in both of the two expressions.

u₁₂ represents the amount of loan remaining after 12 years

<h3>How to interpret u₁₂?</h3>

The function is given as:

u₀ = 8000

u_n = u_{n-1}(1 + 0.054) - 500

Given that the subscript n in u_n represents number of years and u_n represents the amount left to be paid after n years.

We can conclude that:
