A cheetah runs at an average speed of 50 mph between two jungles that are 150 miles apart. An antelope runs at an average speed of 30 mph, a lion runs at an average speed of 25 mph, and an elephant runs at an average speed of 15 mph. The constant variation is ?

cheetah: 3 hours

Antelope: 5 hours

Lion: 6 hours

Elephant: 15 hours

Step-by-step explanation: i choose these answers because of the amount  of time it takes for each animal to run 150 nonstop

50*3=150

30*5= 150

25*6= 150

15*10= 150

Cheetah: 3 hours

Antelope: 5 hours

Lion: 6 hours

Elephant: 10 hours

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

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
