Answer:![\frac{x^2 - 5}{4x + 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5E2%20-%205%7D%7B4x%20%2B%201%7D%20)
, x ≠ -1/4
Explanation:We are given that:
f (x) = 4x + 1
g(x) = x² - 5
We want to find the value of (g/f)(x). This means that we will simply divide g(x) by f(x) as follows:
![( \frac{g}{f} )(x) = \frac{g(x)}{f(x)} = \frac{x^2 - 5}{4x + 1}](https://tex.z-dn.net/?f=%28%20%5Cfrac%7Bg%7D%7Bf%7D%20%29%28x%29%20%3D%20%20%5Cfrac%7Bg%28x%29%7D%7Bf%28x%29%7D%20%3D%20%20%5Cfrac%7Bx%5E2%20-%205%7D%7B4x%20%2B%201%7D%20)
Now, we should note that any function is undefined if its denominator is equal to zero.
This means that for our current function:
4x + 1 cannot be equal to zero
4x + 1 = 0
4x = -1
x = -1/4
This means that the value of x cannot be -1/4, otherwise, our function would be undefined.
Based on the above, the last option is the correct one.
Hope this helps :)
Answer:
L and W +5
Step-by-step explanation:
A1=15*12=180
A2=160+A1=340
340 factors
340,1,2,170,5,..., 20,17
20*17=340
|15-20|=5
|12-17|=5
add 5
Assuming that b>0 and c>0:
log(a)=3×log(b)-2×log(c)=
log(b³)-log(c²)=
log(b³/c²)
Hence a=b³/c²
If it's 5cm x 5 cm x 5cm
Volume is a3
so 125cm

Step-by-step explanation:
<u>Step 1: Define Equation</u>
3(4x - 5) - 4x + 1 = -6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3: 12x - 15 - 4x + 1 = -6
- Combine like terms: 8x - 14 = -6
- Isolate <em>x</em> term: 8x = 8
- Isolate <em>x</em>: x = 1
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 3(4(1) - 5) - 4(1) + 1 = -6
- Multiply: 3(4 - 5) - 4 + 1 = -6
- Subtract: 3(-1) - 4 + 1 = -6
- Multiply: -3 - 4 + 1 = -6
- Subtract: -7 + 1 = -6
- Add: -6 = -6
Here we see that -6 does indeed equal -6.
∴ x = 1 is the solution to the equation.
