18k i believe because it is a varible and a number so when u multiply them u just put them together.... is this multi choice question because to see the answers would help
Answer:
y = -1/4x + 3
Step-by-step explanation:
y=mx+b is the slope-intercept form, which your equation y=4x-4 is already in.
To find the perpendicular line, you must take the <u>negative reciprocal</u> of the slope.
y = -1/4x + b
Your "b" will not be the same as the given equation, since the y-intercepts will not be the same. Therefore, you must solve for it using the point given.
Plug in (4, 2) [general: (x, y)] to the corresponding spots in y = -1/4x + b.
(2) = -1/4(4) + b
2 = -1 + b
b = 3
Now that you know m and b, you can plug all the values back into the form y = mx+b.
**Remember that y and x are never plugged back in! You need two variables to have a linear line
y = -1/4x + 3 is the answer.
Start from
![\dfrac{|10-7|}{4} - \dfrac{|-15+8|}{6}](https://tex.z-dn.net/?f=%5Cdfrac%7B%7C10-7%7C%7D%7B4%7D%20-%20%5Cdfrac%7B%7C-15%2B8%7C%7D%7B6%7D)
Perform the additions inside the absolute values:
![\dfrac{|3|}{4} - \dfrac{|-7|}{6}](https://tex.z-dn.net/?f=%5Cdfrac%7B%7C3%7C%7D%7B4%7D%20-%20%5Cdfrac%7B%7C-7%7C%7D%7B6%7D)
The absolute value does nothing to positive numbers, while it switches the sign of negative numbers, so |3|=3 and |-7|=7:
![\dfrac{3}{4} - \dfrac{7}{6}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B4%7D%20-%20%5Cdfrac%7B7%7D%7B6%7D)
Transform both fractions so that they have the same denominator:
![\dfrac{9}{12} - \dfrac{14}{12} = \dfrac{-5}{12}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B9%7D%7B12%7D%20-%20%5Cdfrac%7B14%7D%7B12%7D%20%3D%20%5Cdfrac%7B-5%7D%7B12%7D%20)
