144.
distributive property distributed a number outside of a parenthesis inside, i.e. x(12•12).
considering there is no given parenthesis, the answer is simply 144.
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where:
m: It is the slope of the line
b: It is the cut point with the y axis
By definition, if two lines are perpendicular then the product of their slopes is -1.
If we have: ![y = 2x-7](https://tex.z-dn.net/?f=y%20%3D%202x-7)
![m_ {1} = 2\\2 * m 2 = - 1\\m_ {2} = - \frac {1} {2}](https://tex.z-dn.net/?f=m_%20%7B1%7D%20%3D%202%5C%5C2%20%2A%20m%202%20%3D%20-%201%5C%5Cm_%20%7B2%7D%20%3D%20-%20%5Cfrac%20%7B1%7D%20%7B2%7D)
Thus, the equation is of the form:
![y = - \frac {1} {2} x + b](https://tex.z-dn.net/?f=y%20%3D%20-%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x%20%2B%20b)
We substitute the point:
![-1 = - \frac {1} {2} (6) + b\\-1 = - \frac {1} {2} (6) + b\\-1 = -3 + b\\-1 + 3 = b\\b = 2](https://tex.z-dn.net/?f=-1%20%3D%20-%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%286%29%20%2B%20b%5C%5C-1%20%3D%20-%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%286%29%20%2B%20b%5C%5C-1%20%3D%20-3%20%2B%20b%5C%5C-1%20%2B%203%20%3D%20b%5C%5Cb%20%3D%202)
Finally, the equation is:
![y = - \frac {1} {2} x + 2](https://tex.z-dn.net/?f=y%20%3D%20-%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x%20%2B%202)
Answer:
![y = - \frac {1} {2} x + 2](https://tex.z-dn.net/?f=y%20%3D%20-%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x%20%2B%202)
Answer:
8.70%
Step-by-step explanation:
Percentage error = (difference between estimated value and actual value / actual amount spent) x 100
difference between estimated value and actual value = estimated value - actual amount
$250 - $230 = $20
($20 / $230) x 100 = 8.6957%
Number two is a type of question of what’s your opinion, but if you really want an answer from someone on the internet, take this:
I would expect the results to not be the same because not everyone has the same type of movie preference.
