Answer:
"The function is decreasing from x = −3 to x = −1."
Step-by-step explanation:
When looking at the first answer choice, we can definitely see that the function value ( g(x) ) is decreasing from x = -3 to x = -1.
At x = -3, the value is 17
At x = -1, the value is -3
So from 17 to -3, the value is really decreasing.
First answer choice is right.
<u>Note:</u> looking at the other choices, they aren't correct
Here is the graph. Work is shown in the picture. I hope this helps.
Answer:
○ b.
Step-by-step explanation:
Since <em>DF</em><em> </em>is a segment bisector, set both expressions equal to each other:
3n - 4 = n + 8
-3n - 3n
__________
−4 = −2n + 8
-8 - 8
_________
−12 = −2n
__ ___
−2 −2
[Plug this back into both expressions above to get the value of 14];
I am joyous to assist you anytime.
A square has equal sides, so the length must equal width.
