(f+g)(-1)
=f(-1)+g(-1), so;
f(x)=3x+8
f(-1)=3(-1)+8
f(-1)=-3+8
f(-1)=5
g(x)=6x+6
g(-1)=6(-1)+6
g(-1)=-6+6
g(-1)=0
Finally:
f(-1)+g(-1)
=5+0
=5. As a result, (f+g)(-1) is 5. Hope it help!
Answer:
The ratio of number of woman to the total number is 19 : 24.
Step-by-step explanation:
Total number of members in the club = 24
Number of men = 5

Answer: 50% increase
Step-by-step explanation:
Think of 20 as 100%
Half of 20 is 10 which is 50% in this scenario.
30-20=10
This means that the price of the item increased by 50% or 10.
To solve this problem,you need to use the formula d = rd (distance = rates x time)She runs at a speed of 7 mph and walks at a speed of 3 mph. Her distance running is d = 7trwhere tr is the time she spends running Her distance walking isd = 3twwhere tw is the time she spends walking The distances are the same so7tr = 3tw We also know that the total time is 4 hourstr + tw = 4tr = 4-tw Substitute this value of tr in the first equation7tr = 3tw7(4-tw) = 3tw28-7tw = 3tw28 = 10tw2.8 = tw Denise will spend 2.8 hours (2 hours, 48 minutes) walking back and 1.2 hours (1 hour, 12 minutes running.
