The algebraic expression for: the sum of a number and 5 decreased by twice the number is (n + 5) - 2n
<h3>Algebra</h3>
let
sum of a number and 5
= n + 5
decreased by twice the number
= -2(n)
= - 2n
sum of a number and 5 decreased by twice the number
= (n + 5) - 2n
= n + 5 - 2n
= 5 - n
Therefore, the algebraic expression which can be used to represent; the sum of a number and 5 decreased by twice the number is (n + 5) - 2n

Answer:
the answer is 2. AB, BC, and CA are the same
The trick here is to substitute points given

substituting point A x-value =b

turns out false since (b,a*b^b) !=(b,0)
substituting point B x-value=0

turns out true since (0,a)=(0,a)
we already got f(x) at x =0 which is not the point (0,0)
so c is false
substituting D x-value=a

hence B is the correct answers
