Point i is on line segment h j ‾ hj . given h i = 2 x , hi=2x, h j = 4 x , hj=4x, and i j = 4 x − 10 , ij=4x−10, determine the numerical length of i j ‾ . ij .

42.4

step-by-step explanation:

convert to decimal

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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

i believe that the answer is

b. y-1=-2(x-4)

hope this !
