Aline passes through the point (4,–2) and is perpendicular to the line with the equation y = 2⁄3x + 4. what's the equation of the line?

y= -3/2x + 1

Step-by-step explanation:

The slope of this line is 2/3. The slope of the line perpendicular to this line will be the negative reciprocal or -3/2.

Write the equation using the slope m=-3/2 and the point slope form.

This is the equation of the line. You can convert it to slope intercept form:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
