-4(5k-7) +2k= -2(9k+5)
Blababa [14]

Answer:

no solutions

Step-by-step explanation:

-4(5k-7) +2k= -2(9k+5)

Distribute

-20k +28 +2k = -18k -10

Combine like terms

-18k +28 = -18k -10

Add 18k to each side

-18k+18k +28 = -18k+18k  -10

28 = -10

This is never true so there are no solutions

Which pair of lines are perpendicular
Gnesinka [82]

The answer is A. A perpendicular equation will have the opposite and reciprocal slope as the original equation.


Once converted to the slope-intercept form of y = mx+b, we find the two equations for A are y = 2x-1 and y = (-1/2)x + 3/2. The opposite reciprocal of the first equation's slope (m in the equation form given) is -1/2, which as you can see if the slope of the other equation.
