![\frac{x}{ - 3.5} + 33 = 30](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B%20-%203.5%7D%20%20%2B%2033%20%3D%2030)
Subtract 33 from the both sides of the equal sign
![\frac{x}{ - 3.5} + (33 - 33) = 30 - 33](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B%20-%203.5%7D%20%2B%20%2833%20-%2033%29%20%20%3D%2030%20-%2033)
Multiply the both sides by -3.5
![( \frac{x}{ - 3.5} ) \times ( - 3.5) = (- 3) \times ( - 3.5)](https://tex.z-dn.net/?f=%28%20%5Cfrac%7Bx%7D%7B%20-%203.5%7D%20%29%20%5Ctimes%20%28%20-%203.5%29%20%3D%20%20%28-%203%29%20%5Ctimes%20%28%20-%203.5%29)
Now X Equals...
Answer:
All of them
Step-by-step explanation:
x² - x - 2
(x + 1)(x - 2)
x² + x - 2x - 2
x² - x - 2
(x - 0.5)² - 2.25
x² - 2(x)(0.5) + 0.5² - 2.25
x² - x + 0.25 - 2.25
x² - x - 2
Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2
l = 14
f(x) increase by a factor of 3
Explanation:
Given that f(x)= 3* and the interval is x=4 to x=57
Now we put the value for x is 4 to 57 then value of f(x) increase with the multiply of 3.
Because the x is multiplied with 3 i.e., 3*
So f(x) increase by a factor of 3.
If we put x=4, then f(x)= 12 (∵ 3×4=12)
If we put x=5, the f(x)= 15 (∵ 3×5=15)
If we put x=6,the f(x)= 18 (∵ 3×6=18)
similarly., values of x= 7,8,9,...155.
Then,
If we put x=56, the f(x)=168
This process will continue until f(x)=171 for x=57.
