Answer:
3
Step-by-step explanation:
(f O g) this basically means that the input x first goes trough the function g and then f. Like f(g(x)).
So when x went trough g, you got the output g(x) and then this went trough f and you got f(g(x)) = -8 = 'f(x)'.
With this in mind you can retrace your steps by first looking at what input can get -8 as an output, for f this is -4. this means g(x) = -4
Then you look at what input (this is the x you're looking for) gets you the ouput -4. Looking at the second image you'll picture see that it's the input 3.

Answer:
D) -0.87
Step-by-step explanation:
I took this test don't quote me on the answer but this is what my peers put.
Your numbers are .17 and .165 meters
Let me explain each digit value:
Lets start with .17
Decimals are like whole numbers where each placement has a digit value
.1 is the tenths place
.07 is the hundredths place
Lets turn to .165
.1 is the tenths place
.06 is the hundredths place
.005 is the thousandths place
When seeing which decimal is larger, go along the tenths place and move along.
So as you can see
, .17 and .165 start with .1 so you can't see which is bigger by this. Now move on to the next digit. Which is larger? .17 or .16? As you should know, 7 is bigger than 6 so that means .17 is larger
Answer: .17 meters is larger than .165 meters
