The answer would be A. 4
Here’s what I would do.
Multiply both sides by 12 so u can get m- 2 by itself.
m-2= 2
How’d I get the two? It comes from when I multiplied 12 on both sides. 12/6= 2
Now ur equation should be
m-2=2
Do the opposite and add two to both sides to get the variable by itself.
m=4
Hope this helps :)))
Answer:
The correct answer is option B.
Step-by-step explanation:
The given rational expression is:
![\frac{x^2-4}{x^2+5x+6}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2-4%7D%7Bx%5E2%2B5x%2B6%7D)
Factor the numerator and the denominator:
![\frac{x^2-2^2}{x^2+2x+3x+6}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2-2%5E2%7D%7Bx%5E2%2B2x%2B3x%2B6%7D)
Factor the numerator using difference of two squares and the denominator using factorization by grouping.
![\frac{(x-2)}{x(x+2)+3(x+2)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-2%29%7D%7Bx%28x%2B2%29%2B3%28x%2B2%29%7D)
![\frac{(x-2)(x+2)}{(x+2)(x+3)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-2%29%28x%2B2%29%7D%7B%28x%2B2%29%28x%2B3%29%7D)
This function is defined if and only if the denominator is not zero.
That is: (x+3)(x+2)≠0.
x≠-2,x≠-3
We simplify now to obtain:
![\frac{x-2}{x+3}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-2%7D%7Bx%2B3%7D)
The correct choice is the second option.
Answer:
The answer is B. n=15/16
Step-by-step explanation:
Answer:
or 120.8 miles per hour
Step-by-step explanation:
We first convert the distance into an improper fraction to facilitate calculation.
![90 \frac{3}{5} = \frac{90\times 5 + 3}{5} = \frac{453}{5}](https://tex.z-dn.net/?f=90%20%5Cfrac%7B3%7D%7B5%7D%20%3D%20%5Cfrac%7B90%5Ctimes%205%20%2B%203%7D%7B5%7D%20%3D%20%5Cfrac%7B453%7D%7B5%7D)
Average speed
= distance/time
=
miles per hour
=
miles per hour
=
miles per hour
=
miles per hour or 120.8 miles per hour
The answer is C because it’s constant but starts further down
