that meen EVALUATE (y) at x=4
y=1
Answer:
-7+4=-3
Step-by-step explanation:
Think of it as adding head to cold (cold being negative numbers). You are adding four "heats" to seven which makes it hotter. The hotter something gets the closer to positive numbers it is. . . so when adding four things if heat to 7 it gets hotter by four therefore it's now at -3.
sorry if that didn't make sense
Set up a ratio for this problem:
.25 in/50 miles = 2.5 in/x
.25x = 125
then divide by .25
The actual distance is: 500 miles
3(6m)+m *Distribute
18m+m *Simplify/Add
19m
19m=19m :)
Answer:
Correct choice is 4, f(6) = 15
Step-by-step explanation:
f(6) means x = 6. If you look at the piecewise function, x = 6 meets the criteria for the second equation which is just 15. You need the first equation ONLY if x is less than 4.
