Remember some simple log rules

log(a)+log(b)=log(ab)
and
log(a)-log(b)=log(\frac{a}{b})

work from left to right

log(12)-log(4)+log(5)=
log(\frac{12}{4})+log(5)=
log(3)+log(5)=
log(3*5)=
log(15)

What is the slope of a line perpendicular to the line whose equation is 2x+4y=-642x+4y=−64. Fully simplify your answer.
labwork [276]

9514 1404 393

Answer:

  2

Step-by-step explanation:

Solving the given equation for y, you have ...

  2x +4y = -64

  4y = -2x -64

  y = -1/2x -16

The coefficient of x is the slope of the given line: -1/2. The slope of the perpendicular line is the opposite reciprocal of this:

  -1/(-1/2) = 2

The slope of the perpendicular line is 2.
