For this question, all we are going to do is plug all 5 of those numbers into the function f(x) = 3x.
The numbers we're given are {3, 4, 6, 7, 9} So lets plug them in!
3*3=9
3*4=12
3*6=18
3*7=21
3*9=27
So the answer is {9, 12, 18, 21, 27}! If you have any questions I'd be happy to help!
Answer:
95degrees
Step-by-step explanation:
75 is the median
And 79 is the mode
Answer:
D
Step-by-step explanation:
step 1: find the slope
slope is 2/-4 = -1/2
then plug in the value for x to y, you get +1 for the y intercept
then it becomes y=-1/2x + 1
I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!
Answer:
Step-by-step explanation: <u>Speed</u> is distance an object travelled per unit time.
It is represented by letter v and can assume various units.
1) 

v = 18 miles per hour
Her average speed is 18 mph.
2) Rearraging formula for distance:
d = v.t
d = 70 * 4
d = 280 miles
You would travel 280 miles.
3) 

v = 52.5 mph
My average speed is 52.5 mph.
4) Rearranging formula to determine time:


t = 2.34 hours
It will take 2 hours and half to arrive in Leeds. So, we will be expected to arrive at 12:04.
5) The unit change but the way of calculating time is the same.

t = 500 s
or t = 8.34 minutes
It will take, for an athlete to run 2000m, 8.34 minutes.
6) a) All units must match, so for a speed in mph:
45 minutes is 0.75 hours. Total time is 8.75 hours.

v = 560 mph
The average speed is 560 mph.
b) 

t = 6.67 hours
Sam will take 6.67 hours to covered the distance.
