Complete the equation of the line through (-9,-9) (-6,0)

y=3x+18

Step-by-step explanation:

find the slope of the line with the formula m=(y1-y2)/(x1-x2) =-9-0/-9+6=-9/-3=3

then use the equation (y-y1)= m(x-x1) where you use slope m=3 and one of the points (y-0)=3(x+6), y=3x+18

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

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
