Answer:
I believe... x=12
Step-by-step explanation:
5x = 4x + 12
5x - 4x = x
therefore, x = 12

Answer:</h2>
The derivative of the function f(x) is:
<h2>
Step-by-step explanation:</h2>
We are given a function f(x) as:
We have:
( Since,
)
Hence, we get:
Also, by using the definition of f'(x) i.e.
Hence, on putting the value in the formula:
Hence, the derivative of the function f(x) is:
Answer:
1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

1) Point-slope form
(y-y1)=m(x-x1)
m= - 3,
point (3,-4), so x1 = 3, y1 = - 4.
(y+4)= -3(x- 3)
2)Point-slope form
(y-y1)=m(x-x1)
m= - 3/4,
point (4,5), so x1 = 4, y1 = 5.
(y-5)= - 3/4(x-4)
Answer:
-3
Step-by-step explanation:
First, you can factor out a 6:
Next, you can factor the quadratic:
Since the only value of x that could set this equation equal to 0 is -3, that is the answer. Hope this helps!
