Write an euqation of a line that is perpendicular to y=1/2x+3 and passes through the point (10,-5)

Step-by-step explanation:

Slope of the perpendicular line = (-1)/(1/2) = -2.

y = -2x + c. When x = 10, y = -5.

=> (-5) = -2(10) + c, c = 15.

Hence the equation of the line is y = -2x + 15.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
