A line perpendicular to 3x + 2y = 18 has a slope of .

2/3

Step-by-step explanation:

A line perpendicular to another line has a opposite reciprocal slope.

For example, if a line has a slope of 5, then the perpendicular line will have a slope of -1/5.

First, put the formula into slope intercept form:

3x + 2y = 18

2y = -3x + 18

y = -3/2x + 9

Because this line has a slope of -3/2, the perpendicular line will have a slope of 2/3.

sorry if this isnt what you're looking for i dont really understand the question

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
