Answer:
16
Step-by-step explanation:
I am not exactly sure of what you mean by "simplify by making an expression", but I will do both for your sake.
The expression is 5 * 3 - 9 + 10. Simplified, that is 16.
Answer : option B
![f(x) = 3x^3 + 10x^2 + 4x - 8](https://tex.z-dn.net/?f=f%28x%29%20%3D%203x%5E3%20%2B%2010x%5E2%20%2B%204x%20-%208)
We have -2 in the given option
Lets use synthetic division and divide by -2
First write the coefficient of all the terms in f(x)
-2 3 10 4 -8
0 -6 -8 8
------------------------------------------------------
3 4 -4 0
We got remainder =0 , so -2 is one of the zero
Resultant expression is 3x^2 + 4x -4
Lets use synthetic division and divide by -2 again
-2 3 4 -4
0 -6 4
------------------------------------------------------
3 -2 0
We got remainder =0 , so -2 is again a zero
Resultant expression is 3x - 2
we set 3x -2 =0
Add 2 on both sides
3x = 2
Divide by 3 on both sides
![x = \frac{2}{3}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B2%7D%7B3%7D)
So zeros are ![-2, \frac{2}{3}](https://tex.z-dn.net/?f=-2%2C%20%5Cfrac%7B2%7D%7B3%7D)
You have to calculate how many ways you can select six things (r)
from a set of 9 things (n). (See attached formula).
9! / 6! * (3!) =
9*8*7 * 6! / 6! * 3! =
9*8*7 / 3! =
3 * 4 * 7 = 84 lineups
Answer:
it's a transformation of 2 units left and 3 units to the down
11÷2.21=4.97
Rounded to the nearest tenth is 5.0
