Answer:
D
Step-by-step explanation:
The sum of a number and twenty-three less than that number" as a mathematical expression is x + (x – 23)
I mean its the only answer with sum and "less than" because that usually means you need to subtract, I hope this helps
5 - 8 would be a negative answer
think of it as a bank account if you $5 in the account and you take away $8, how much would you have after? $-3 so your answer would be -3
and same with -5-(-3)
this would be -2
The polynomial will be found as follows;
given that the solution is x=6,x=2 and x=-7, it implies that roots are :
(x-6), (x-2) and (x+7)
Therefore the polynomial will be:
y=(x-6)(x-2)(x+7)
y=x^3-x^2-44x+84
Respuesta:
Allí está el proceso, de nada <3
Do the x first it gives u the number then plot y
