9x+6x=15x
Answer:
Step-by-step explanation:
Time taken for task 1:
Distance= 750m= 0.75 km
Speed= 10 km/hr
Time taken1= S (distance)/ V (speed)= 0.75/10= 0.075 hr= 4 mins and 30 sec
Time taken for task 2:
t2=S/V= 20/85= 0.24 hr= 14 mins and 24 sec
Time taken for task 3:
t3= S/V = 5/14= 0.36 hr= 21 mins and 36 sec
Total time took:
T1 +T2+T3= 40 mins and 30 second (approximately)
I'm pretty sure the attachment down there can answer ur question! :D
Answer:
domain is (-∞,∞)
(-∞,0) U(0,∞)
Step-by-step explanation:

The domain is the set of x values for which the function is defined
In f(x) there is no restriction for x. the function is defined for all x values
so domain is (-∞,∞)

The domain is the set of x values for which the function is defined
when x=0, e^0=1 that makes the denominator 0
Denominator 0 is undefined. So x cannot be 0
domain is (-∞,0) U(0,∞)
X=2
y=-2-2x=-2-4=-6
so you choose a
