Answer:
Step-by-step explanation:
1.5070-1070=4000 loss
2.7505-5080=2425 loss
3. 1700-1570=30 profit
Answer:
A
Step-by-step explanation:
We have the two functions:
[tex]\begin{gathered}f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\\end{gathered} [/tex]
And we want to find:
(f-g)(x)(f−g)(x)
This is equivalent to:
=f(x)-g(x)=f(x)−g(x)
Hence, by substitution:
[tex]=(3x^2-2x)-(9x^2-x+7)[/tex]
Distribute:
[tex]=(3x^2-2x)+(-9x^2+x-7)[/tex]
Rearrange:
[tex]=(3x^2-9x^2)+(-2x+x)+(-7)[/tex]
Combine like terms:
[tex]=-6x^2-x-7[/tex]
Hence, our answer is A.
