Given:
The expression is 
.
To find:
The position of parentheses inserted in the expression to get the value 19
Step-by-step explanation:
We have,
Now,
There are more ways to apply the parenthesis, but we do not get 19.
And many more possibilities.
Therefore, the expression after inserting the parentheses is 
.
Answer:
From -2<x<-1, the function F(X) is increasing. (B)
Really, it increases all from around -2.5<x<0.5
C is also the second answer, as it increases til around 2.5
It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.
Which means (B) is your answer.
If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.
Answer: The answer to that would be 4/5= 32/40.
Step-by-step explanation: It is 4/5 =32/40 because if you were to divide the 40 by the 5 you would get 8. Since you got 8 when dividing 40 by 5 you would multiply 8x4. You would do this because whatever you do to the denominator you would do to the numerator. So you would multiply 4/5 x 8/8 and get 32/40. PLEASE MARK BRAINLIEST!!!!
Answer:
n = 2
Step-by-step explanation:
0.5n - 2 - 3 = 3 - 2n -3
0.5n + 2n = 2 + 3 + 3 -3
2.5n = 5
n = 2
