Answer:
Step-by-step explanation:
the constant drain of water is C:
C= (1000-940)/10 = 6 gallons per minute
after x minutes : 1000- 6x ( water left in the tank after x minutes)
for 5 minutes: 1000-6(5)=970
after 20 min.: 1000-6(20)=880
after 30 min.: 1000-6(30)=820
after 27 min.: 1000-6(27)= 838
the rate of flow of water is 6 gallon per minute
7a + 6c + 9a - 15c
-- Look for all the 'a's 7a, 9a
-- Addum up 16a
-- Look for all the 'c's 6c, -15c
-- Addum up -9c
-- Write the results 16a - 9c
Answer:
360 ≥ 8t
Step-by-step explanation:
Let t be the number of tables. Since there can't be more than 360 people, it has to be less than or equal to.
Put x = 2 in f(x) you'll get,f(2) = 2(3) x 2 = 12. so next point could be ( 2,12)
(3,6)
4x + y > 19
4(3) + 6 > 19
12 + 6 > 19
18 > 19
No
