Answer:
-f(-x) = f(x)
Step-by-step explanation:
Given function is:
f(x)= -2x^5+x^3-7x
To check if a function is even, it is checked that:
f(-x)=f(x)
If f(-x) gives the original function then the function is said to be even.
And if:
-f(-x)=f(x)
which means if –f(-x) gives the original function, then the function is odd. So a function has to satisfy this rule to be an odd function.
Now for the given function:
-f(-x)= -[-2(-x)^5+(-x)^3-7(-x)]
= -[(-2)(-x^5 )+(-x^3 )+7x]
= -( 2x^5- x^3+7x)
Multiplying the negative sign
-f(-x)= -2x^5+x^3-7x
-f(-x)=f(x)
So, the function satisfies this rule to be an odd function. ..
Answer:
1.5
Step-by-step explanation:
Let the unknown number be x.
12 - 5x = 3x
12 = 3x + 5x = 8x
. : x = 12/8 = 3/2 = 1.5
Answer- 1 5/6 of the hamburger meat did not get thrown away.
Step-by-step explanation-
1. Turn the mixed numbers into fractions. 6 1/2=13/2
4 2/3= 14/3
2. Subtract. To do this you have to make sure that both fractions have the same denominator (bottom number) I did that by multiplying the bottom numbers by each other, and whatever you do to the top you do to the bottom. So it will turn out to be 39/6 - 28/6 = 11/6 or 1 5/6
