Let f(x)=0, you'll get x=3 and x=-5, those are the x-intercepts of the function.
Answer:
6 6/7 km/h
Step-by-step explanation:
The relations between speed, time, and distance are ...
time = distance/speed
speed = distance/time
__
So, to find the average speed, we need to know the total distance and the total time. The distances are given, but we need to compute the times.
time jogging = (2 km)/(8 km/h) = 1/4 h
time walking = (2 km)/(6 km/h) = 1/3 h
Then the woman's average speed is ...
average speed = (total distance)/(total time) = (2 km + 2 km)/(1/4 h + 1/3 h)
= (4 km)/(7/12 h) = 48/7 km/h
= 6 6/7 km/h
Answer:
the answer is A
Step-by-step explanation:
Answer:
I'm pretty sure its -4-12x but I could be wrong
Step-by-step explanation:
First I tried to solve for x but got -12x+4 so to get 4 on the other side of the equation I subtracted and got -4-12x I hope this helps :)
The answer is going to be c because 12-35=23 and since there is variables you have to add the variable.
