Answer:
these are different
Step-by-step explanation:
7x^0 is only x to the 0th power
(7x)^0 the 0th power is distributed to both the 7 and x
My test say the answer is A
So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.
So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.
f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10
I believe the answer is 6 white marbles. how i figured that out was i made an equation. i took the variable Y (for the yellow marbles) times 2 minus 6 equals 18. you then add 6 to the other side of the equal sign to cancel out the 6. you then have y(2)=24. you divide y and 24 by 2. you get 12 yellow marbles. next step is to take 18 - 12. you are left with 6 white marbles. hope this helps!
From the 3 options listed, both

in and

in could be measures found using a ruler with eighth inches marked, because those decimals can be written in terms of eighth fractions.

The other option,

in, is not a possibility because 0.1 cannot be written as a fraction of 8 that is marked on the ruler.
