5 + 2x ≤ 27 is the answer
Answer:
True
Step-by-step explanation:
Let B={} a set of vectors containing the zero vector.
B is linear dependent if exist scalars not all zero such that .
Observe that if and then
.
Then B is linear dependent.
5 trumpet players
let s represent saxophone players and t trumpet players
thus t = s - 10 → ( 10 less than saxophone players)
also s = 3t = 3( s - 10)
solve s = 3( s - 10)
s = 3s - 30
subtract s from both sides of the equation
0 = 3s - s - 30
0 = 2s - 30
add 30 to both sides
30 = 2s
divide both sides by 2
= s ⇒ s = 15
number of trumpet players = 15 - 10 = 5
Answer:
The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
Step-by-step explanation:
The difference between continuous and discrete graphs and functions is that a discrete function allows the variables to be only certain points in the interval, usually only integers; meanwhile, a continuous function allows the variables to be any points in the interval. Here, both variables are discrete, that is, the number of people is {0, 1, 2, 3, ...}, and days are {Monday, Tuesday, Wednesday, ...}
