Given:
The two functions are:
To find:
The value of .
Solution:
We have,
We know that,
Putting , we get
Therefore, the value of is 2401.
Let x = your number.
6x = x^2 - 27. Subtract 6x from each side.
0 = x^2 - 6x - 27. Factor
0 = (x-9) (x+3). Set each term equal to zero
(x+3) = 0. Subtract 3 from each side.
x = -3. This is the negative solution.
(x-9) = 0. Add 9 to each side.
x = 9. This is the positive solution.
Answer:
Exact form : x = 67/3
Decimal form : x = 22.33333333333...
Mixed Number form : x = 22 1/3
Step-by-step explanation: Solve for x by simplifying both sides of the equation, then isolating the variable.
I hope this helps you out. :)
Answer:
B
Step-by-step explanation:
Divide both sides by 3
Take square root of both sides.
Add 9 to both sides.
17 out of 20 is 85 percent.
