Answer:
x=5
Step-by-step explanation:
F(x)=-3x+21,
f(x)=6 = -3x+21
6 = -3x+21
Subtract 21 from each side
6-21 = -3x+21-21
-15 = -3x
Divide each side by -3
-15/-3 = -3x/-3
5 = x
Answer: 225

Answer:
do you mean "what is A descriminate?"
Step-by-step explanation:
Answer: "
-2y³ + 3y²<span>
+ 27y " .
_______________________________________________________Refer to the completed chart below (image attached).</span>
_______________________________________________________Using the completed chart below (image attached), we can write out the terms:
__________________________________________________ y³ − 3y³ + 9y² + 3y² − 9y² + 27y ;
Then, we can combine the "like terms" ;
__________________________________________y³ − 3y³ = -2y³ ;
+9y² + 3y² − 9y² = + 3y² ;
___________________________________________________________to get: -2y³ + 3y² ; and bring down the "+27y" ;
___________________________________________________________ Answer: "
-2y³ + 3y²<span>
+ 27y " . </span>Refer to chart below (image attached).

Answer:
4 (RootIndex 3 StartRoot 6 x squared EndRoot) = 4![\sqrt[3]{6x^2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6x%5E2%7D)
Step-by-step explanation:
- <em>Added radical forms to the question for better visibility.</em>
Which of the following is a like radical to RootIndex 3 StartRoot 6 x squared EndRoot =
?
- x (RootIndex 3 StartRoot 6 x EndRoot) = x
![\sqrt[3]{6x}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6x%7D)
- 6 (RootIndex 3 StartRoot x squared EndRoot) = 6
![\sqrt[3]{x^2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E2%7D)
- 4 (RootIndex 3 StartRoot 6 x squared EndRoot) = 4
![\sqrt[3]{6x^2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6x%5E2%7D)
- x (RootIndex 3 StartRoot 6 EndRoot) = x
![\sqrt[3]{6}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6%7D)
<h3>Solution</h3>
- <em>Like radicals are radicals that have the same root number and expression under the root.</em>
1) x
= ![\sqrt[3]{6x^4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6x%5E4%7D)
2) 6
= ![\sqrt[3]{6^3x}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6%5E3x%7D)
3) 4
4) x
= ![\sqrt[3]{6x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6x%5E3%7D)
Compared with the given radical, we can see from the given choices only 3rd choice is like radical with
