HS: Algebra 2A [M] (Prescriptive) (GP)/ 5 Quadratic Functions
ipn [44]

Answer:

Linear, the linear term is -21x and the constant term is -20. Last option is the answer

Step-by-step explanation:

We are given the following function:

y = (x - 5)(5x + 4) - 5x^2

First we have to simplify y, before solving the question:

y = (x - 5)(5x + 4) - 5x

Applying the distributive property:

y = 5x^2 + 4x - 25x - 20 - 5x^2

y = 0x^2 - 21x - 20

y = -21x - 20

No quadratic term, so it is linear.

The linear term is -21x and the constant term is -20.

3/4n - 18 = 1/4n - 4
kolezko [41]
3/4n -18= 1/4n -4
⇒ 3/4n -1/4n= -4+18
⇒ 2/4n= 14
⇒ 1/2n= 14
⇒ n= 14/(1/2)
⇒ n= 14* (2/1)
⇒ n= 28

Final answer: n= 28~
