Use of property: log(ab) = log(a) + log(b)

log7(x²+5x−14)−log7(x+7) =

log7(x+7)(x-2) - log7(x+7) =

log7(x+7) + log7(x-2) - log7(x+7) =

bezimeni [28]

Change into slope-intercept form:

y= -3/4x + 5

We will be using the point slope formula to write the perpendicular equation:

y - y1 = m (x - x1)

y + 2 = 4/3(x + 3)

y + 2 = 4/3x + 4

y = 4/3x + 2

Answer:

y = 4/3x + 2
