He paid $643.5 for it originally
585 x .1 = 58.5
585+58.5= 643.5
hope this helps
Answer:
d)-8
Step-by-step explanation:
- -6s-¹t²
- -6(3)-¹(-2)²
- -6(⅓)(4)
- -8
To check whether a function is odd or even, we simply substitute the argument by its negative version, namely "x" by "-x".
if the expression simplifies to resemble the original expression, that simply means the expression is
even. If it resembles the original negative expression, is
odd.
![\bf g(x)=-2x^3-9\\\\ -------------------------------\\\\ \stackrel{x=-x}{g(-x)}=-2(-x)^3-9\implies g(-x)=-2(-x)(-x)(-x)-9 \\\\\\ g(-x)=+2(x)(x)(x)-9\implies g(-x)=2x^3-9](https://tex.z-dn.net/?f=%5Cbf%20g%28x%29%3D-2x%5E3-9%5C%5C%5C%5C%0A-------------------------------%5C%5C%5C%5C%0A%5Cstackrel%7Bx%3D-x%7D%7Bg%28-x%29%7D%3D-2%28-x%29%5E3-9%5Cimplies%20g%28-x%29%3D-2%28-x%29%28-x%29%28-x%29-9%0A%5C%5C%5C%5C%5C%5C%0Ag%28-x%29%3D%2B2%28x%29%28x%29%28x%29-9%5Cimplies%20g%28-x%29%3D2x%5E3-9)
well, that doesn't look like the original
- 2x³ - 9, so is not
even.
and -f(x) would be
2x³ + 9, and that doesn't look like either, so is not
odd.
thus is neither.
