I need to know the bottom part pls

Step-by-step explanation:

j + d = 895

j = d + 177

Let us substitute the second equation into the first one for j.

So the first equation can be rewritten as (d + 177) + d = 895

=> 2d + 177 - 177 = 895 - 177

=> 2d = 718

=> 2d/2 = 718/2

=> d = 359

=> j = 359 + 177

=> j = 536

Checking your

j + d = 536 + 359 = 895

0.5 meters per second

step-by-step explanation:

the average speed between 2 seconds and 8 seconds is 0.5 meters per second.

hope this ! mark brainliest!

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
