Answer:Commutative property
Step-by-step explanation:
He has 10 pets in total (7 cats + 3 dogs).
He has $92.
Divide $92 by 10 to get the answer, which is $9.2.
In fraction format, it would be 9 1/5. 0.2 would equal 2/10, which can be simplified to be 1/5. Then, you add 9.
The amount in dollars in cents would be $9.20
F(x2-5)=4x2-19 is the answer
6,636 and the estimate is 6,600 if your estimating to the hundreds
Step-by-step explanation:
If the polynomial is rational, then one of zeros is 3 + 2i.
We are also given f(x) is decreasing function, it means the leading coefficient is negative.
<u>The factors would be:</u>
- f(x) = - (x - 7)(x - (3 - 2i))(x - (3 + 2i)
or
- f(x) = - (x - 7)(x - 3+ 2i)(x - 3 - 2i)
